Menorrhagia is the medical term for menstrual periods with abnormally heavy or prolonged bleeding. Although heavy menstrual bleeding is a common concern, most women don't experience blood loss severe enough to be defined as menorrhagia.

With menorrhagia, you can't maintain your usual activities when you have your period because you have so much blood loss and cramping. If you dread your period because you have such heavy menstrual bleeding, talk with your doctor. There are many effective treatments for menorrhagia.

Symptoms

Signs and symptoms of menorrhagia may include:

• Soaking through one or more sanitary pads or tampons every hour for several consecutive hours
• Needing to use double sanitary protection to control your menstrual flow
• Needing to wake up to change sanitary protection during the night
• Bleeding for longer than a week
• Passing blood clots larger than a quarter
• Restricting daily activities due to heavy menstrual flow
• Symptoms of anemia, such as tiredness, fatigue or shortness of breath

When to see a doctor

Seek medical help before your next scheduled exam if you experience:

• Vaginal bleeding so heavy it soaks at least one pad or tampon an hour for more than two hours
• Bleeding between periods or irregular vaginal bleeding
• Any vaginal bleeding after menopause

Causes

• Hormone imbalance. In a normal menstrual cycle, a balance between the hormones estrogen and progesterone regulates the buildup of the lining of the uterus (endometrium), which is shed during menstruation. If a hormone imbalance occurs, the endometrium develops in excess and eventually sheds by way of heavy menstrual bleeding.
  A number of conditions can cause hormone imbalances, including polycystic ovary syndrome (PCOS), obesity, insulin resistance and thyroid problems.
• Dysfunction of the ovaries. If your ovaries don't release an egg (ovulate) during a menstrual cycle (anovulation), your body doesn't produce the hormone progesterone, as it would during a normal menstrual cycle. This leads to hormone imbalance and may result in menorrhagia.
• Uterine fibroids. These noncancerous (benign) tumors of the uterus appear during your childbearing years. Uterine fibroids may cause heavier than normal or prolonged menstrual bleeding.
• Polyps. Small, benign growths on the lining of the uterus (uterine polyps) may cause heavy or prolonged menstrual bleeding.
• Adenomyosis. This condition occurs when glands from the endometrium become embedded in the uterine muscle, often causing heavy bleeding and painful periods.
• Intrauterine device (IUD). Menorrhagia is a well-known side effect of using a nonhormonal intrauterine device for birth control. Your doctor will help you plan for alternative management options.
• Pregnancy complications. A single, heavy, late period may be due to a miscarriage. Another cause of heavy bleeding during pregnancy includes an unusual location of the placenta, such as a low-lying placenta or placenta previa.
• Cancer. Uterine cancer and cervical cancer can cause excessive menstrual bleeding, especially if you are postmenopausal or have had an abnormal Pap test in the past.
• Inherited bleeding disorders. Some bleeding disorders — such as von Willebrand's disease, a condition in which an important blood-clotting factor is deficient or impaired — can cause abnormal menstrual bleeding.
• Medications. Certain medications, including anti-inflammatory medications, hormonal medications such as estrogen and progestins, and anticoagulants such as warfarin (Coumadin, Jantoven) or enoxaparin (Lovenox), can contribute to heavy or prolonged menstrual bleeding.
• Other medical conditions. A number of other medical conditions, including liver or kidney disease, may be associated with menorrhagia.

Risk factors

Risk factors vary with age and whether you have other medical conditions that may explain your menorrhagia. In a normal cycle, the release of an egg from the ovaries stimulates the body's production of progesterone, the female hormone most responsible for keeping periods regular. When no egg is released, insufficient progesterone can cause heavy menstrual bleeding.

Menorrhagia in adolescent girls is typically due to anovulation. Adolescent girls are especially prone to anovulatory cycles in the first year after their first menstrual period (menarche).

Menorrhagia in older reproductive-age women is typically due to uterine pathology, including fibroids, polyps and adenomyosis. However, other problems, such as uterine cancer, bleeding disorders, medication side effects and liver or kidney disease must be ruled out.

Complications

Excessive or prolonged menstrual bleeding can lead to other medical conditions, including:

• Anemia. Menorrhagia can cause blood loss anemia by reducing the number of circulating red blood cells. The number of circulating red blood cells is measured by hemoglobin, a protein that enables red blood cells to carry oxygen to tissues.
  Iron deficiency anemia occurs as your body attempts to make up for the lost red blood cells by using your iron stores to make more hemoglobin, which can then carry oxygen on red blood cells. Menorrhagia may decrease iron levels enough to increase the risk of iron deficiency anemia.
  Signs and symptoms include pale skin, weakness and fatigue. Although diet plays a role in iron deficiency anemia, the problem is complicated by heavy menstrual periods.
• Severe pain. Along with heavy menstrual bleeding, you might have painful menstrual cramps (dysmenorrhea). Sometimes the cramps associated with menorrhagia are severe enough to require medical evaluation.

Endometriosis (en-doe-me-tree-O-sis) is an often painful disorder in which tissue that normally lines the inside of your uterus — the endometrium — grows outside your uterus. Endometriosis most commonly involves your ovaries, fallopian tubes and the tissue lining your pelvis. Rarely, endometrial tissue may spread beyond pelvic organs.

With endometriosis, displaced endometrial tissue continues to act as it normally would — it thickens, breaks down and bleeds with each menstrual cycle. Because this displaced tissue has no way to exit your body, it becomes trapped. When endometriosis involves the ovaries, cysts called endometriomas may form. Surrounding tissue can become irritated, eventually developing scar tissue and adhesions — abnormal bands of fibrous tissue that can cause pelvic tissues and organs to stick to each other.

Endometriosis can cause pain — sometimes severe — especially during your period. Fertility problems also may develop. Fortunately, effective treatments are available.

Symptoms

The primary symptom of endometriosis is pelvic pain, often associated with your menstrual period. Although many women experience cramping during their menstrual period, women with endometriosis typically describe menstrual pain that's far worse than usual. They also tend to report that the pain increases over time.

Common signs and symptoms of endometriosis may include:

• Painful periods (dysmenorrhea). Pelvic pain and cramping may begin before your period and extend several days into your period. You may also have lower back and abdominal pain.
• Pain with intercourse. Pain during or after sex is common with endometriosis.
• Pain with bowel movements or urination. You're most likely to experience these symptoms during your period.
• Excessive bleeding. You may experience occasional heavy periods (menorrhagia) or bleeding between periods (menometrorrhagia).
• Infertility. Endometriosis is first diagnosed in some women who are seeking treatment for infertility.
• Other symptoms. You may also experience fatigue, diarrhea, constipation, bloating or nausea, especially during menstrual periods.

The severity of your pain isn't necessarily a reliable indicator of the extent of the condition. Some women with mild endometriosis have intense pain, while others with advanced endometriosis may have little pain or even no pain at all.

Endometriosis is sometimes mistaken for other conditions that can cause pelvic pain, such as pelvic inflammatory disease (PID) or ovarian cysts. It may be confused with irritable bowel syndrome (IBS), a condition that causes bouts of diarrhea, constipation and abdominal cramping. IBS can accompany endometriosis, which can complicate the diagnosis.

When to see a doctor

See your doctor if you have signs and symptoms that may indicate endometriosis.

Endometriosis can be a challenging condition to manage. An early diagnosis, a multidisciplinary medical team and an understanding of your diagnosis may result in better management of your symptoms.

Causes

Although the exact cause of endometriosis is not certain, possible explanations include:

• Retrograde menstruation. In retrograde menstruation, menstrual blood containing endometrial cells flows back through the fallopian tubes and into the pelvic cavity instead of out of the body. These displaced endometrial cells stick to the pelvic walls and surfaces of pelvic organs, where they grow and continue to thicken and bleed over the course of each menstrual cycle.
• Transformation of peritoneal cells. In what's known as the "induction theory," experts propose that hormones or immune factors promote transformation of peritoneal cells — cells that line the inner side of your abdomen — into endometrial cells.
• Embryonic cell transformation. Hormones such as estrogen may transform embryonic cells — cells in the earliest stages of development — into endometrial cell implants during puberty.
• Surgical scar implantation. After a surgery, such as a hysterectomy or C-section, endometrial cells may attach to a surgical incision.
• Endometrial cells transport. The blood vessels or tissue fluid (lymphatic) system may transport endometrial cells to other parts of the body.
• Immune system disorder. It's possible that a problem with the immune system may make the body unable to recognize and destroy endometrial tissue that's growing outside the uterus.

Risk factors

Several factors place you at greater risk of developing endometriosis, such as:

• Never giving birth
• Starting your period at an early age
• Going through menopause at an older age
• Short menstrual cycles — for instance, less than 27 days
• Having higher levels of estrogen in your body or a greater lifetime exposure to estrogen your body produces
• Low body mass index
• Alcohol consumption
• One or more relatives (mother, aunt or sister) with endometriosis
• Any medical condition that prevents the normal passage of menstrual flow out of the body
• Uterine abnormalities

Endometriosis usually develops several years after the onset of menstruation (menarche). Signs and symptoms of endometriosis end temporarily with pregnancy and end permanently with menopause, unless you're taking estrogen.

Complications

Infertility

The main complication of endometriosis is impaired fertility. Approximately one-third to one-half of women with endometriosis have difficulty getting pregnant.

For pregnancy to occur, an egg must be released from an ovary, travel through the neighboring fallopian tube, become fertilized by a sperm cell and attach itself to the uterine wall to begin development. Endometriosis may obstruct the tube and keep the egg and sperm from uniting. But the condition also seems to affect fertility in less-direct ways, such as damage to the sperm or egg.

Even so, many women with mild to moderate endometriosis can still conceive and carry a pregnancy to term. Doctors sometimes advise women with endometriosis not to delay having children because the condition may worsen with time.

Ovarian cancer

Ovarian cancer does occur at higher than expected rates in women with endometriosis. But the overall lifetime risk of ovarian cancer is low to begin with. Some studies suggest that endometriosis increases that risk, but it's still relatively low. Although rare, another type of cancer — endometriosis-associated adenocarcinoma — can develop later in life in women who have had endometriosis.

Menopause is the time that marks the end of your menstrual cycles. It's diagnosed after you've gone 12 months without a menstrual period. Menopause can happen in your 40s or 50s, but the average age is 51 in the United States.

Menopause is a natural biological process. But the physical symptoms, such as hot flashes, and emotional symptoms of menopause may disrupt your sleep, lower your energy or affect emotional health. There are many effective treatments available, from lifestyle adjustments to hormone therapy.

Symptoms

In the months or years leading up to menopause (perimenopause), you might experience these signs and symptoms:

• Irregular periods
• Vaginal dryness
• Hot flashes
• Chills
• Night sweats
• Sleep problems
• Mood changes
• Weight gain and slowed metabolism
• Thinning hair and dry skin
• Loss of breast fullness

Symptoms, including changes in menstruation, are different for every woman. Most likely, you'll experience some irregularity in your periods before they end.

Skipping periods during perimenopause is common and expected. Often, menstrual periods will skip a month and return, or skip several months and then start monthly cycles again for a few months. Periods also tend to happen on shorter cycles, so they are closer together. Despite irregular periods, pregnancy is possible. If you've skipped a period but aren't sure you've started the menopausal transition, consider a pregnancy test.

When to see a doctor

Keep up with regular visits with your doctor for preventive health care and any medical concerns. Continue getting these appointments during and after menopause.

Preventive health care as you age may include recommended health screening tests, such as colonoscopy, mammography and triglyceride screening. Your doctor might recommend other tests and exams, too, including thyroid testing if suggested by your history, and breast and pelvic exams.

Always seek medical advice if you have bleeding from your vagina after menopause.

Causes

Menopause can result from:

• Natural decline of reproductive hormones. As you approach your late 30s, your ovaries start making less estrogen and progesterone — the hormones that regulate menstruation — and your fertility declines. In your 40s, your menstrual periods may become longer or shorter, heavier or lighter, and more or less frequent, until eventually — on average, by age 51 — your ovaries stop producing eggs, and you have no more periods.
• Hysterectomy. A hysterectomy that removes your uterus but not your ovaries usually doesn't cause immediate menopause. Although you no longer have periods, your ovaries still release eggs and produce estrogen and progesterone. But surgery that removes both your uterus and your ovaries (total hysterectomy and bilateral oophorectomy) does cause immediate menopause. Your periods stop immediately, and you're likely to have hot flashes and other menopausal signs and symptoms, which can be severe, as these hormonal changes occur abruptly rather than over several years.
• Chemotherapy and radiation therapy. These cancer therapies can induce menopause, causing symptoms such as hot flashes during or shortly after the course of treatment. The halt to menstruation (and fertility) is not always permanent following chemotherapy, so birth control measures may still be desired.
• Primary ovarian insufficiency. About 1 percent of women experience menopause before age 40 (premature menopause). Menopause may result from primary ovarian insufficiency — when your ovaries fail to produce normal levels of reproductive hormones — stemming from genetic factors or autoimmune disease. But often no cause can be found. For these women, hormone therapy is typically recommended at least until the natural age of menopause in order to protect the brain, heart and bones.

Complications

After menopause, your risk of certain medical conditions increases. Examples include:

• Heart and blood vessel (cardiovascular) disease. When your estrogen levels decline, your risk of cardiovascular disease increases. Heart disease is the leading cause of death in women as well as in men. So it's important to get regular exercise, eat a healthy diet and maintain a normal weight. Ask your doctor for advice on how to protect your heart, such as how to reduce your cholesterol or blood pressure if it's too high.
• Osteoporosis. This condition causes bones to become brittle and weak, leading to an increased risk of fractures. During the first few years after menopause, you may lose bone density at a rapid rate, increasing your risk of osteoporosis. Postmenopausal women with osteoporosis are especially susceptible to fractures of their spine, hips and wrists.
• Urinary incontinence. As the tissues of your vagina and urethra lose elasticity, you may experience frequent, sudden, strong urges to urinate, followed by an involuntary loss of urine (urge incontinence), or the loss of urine with coughing, laughing or lifting (stress incontinence). You may have urinary tract infections more often.
  Strengthening pelvic floor muscles with Kegel exercises and using a topical vaginal estrogen may help relieve symptoms of incontinence. Hormone therapy may also be an effective treatment option for menopausal urinary tract and vaginal changes which can result in urinary incontinence.
• Sexual function. Vaginal dryness from decreased moisture production and loss of elasticity can cause discomfort and slight bleeding during sexual intercourse. Also, decreased sensation may reduce your desire for sexual activity (libido).
  Water-based vaginal moisturizers and lubricants may help. If a vaginal lubricant isn't enough, many women benefit from the use of local vaginal estrogen treatment, available as a vaginal cream, tablet or ring.
• Weight gain. Many women gain weight during the menopausal transition and after menopause because metabolism slows. You may need to eat less and exercise more, just to maintain your current weight.

A Pap smear, also called a Pap test, is a procedure to test for cervical cancer in women.

A Pap smear involves collecting cells from your cervix — the lower, narrow end of your uterus that's at the top of your vagina.

Detecting cervical cancer early with a Pap smear gives you a greater chance at a cure. A Pap smear can also detect changes in your cervical cells that suggest cancer may develop in the future. Detecting these abnormal cells early with a Pap smear is your first step in halting the possible development of cervical cancer.

Why it's done

A Pap smear is used to screen for cervical cancer. The Pap smear is usually done in conjunction with a pelvic exam. In women older than age 30, the Pap test may be combined with a test for human papillomavirus (HPV) — a common sexually transmitted infection that can cause cervical cancer in some women.

Who should have a Pap smear?

You and your doctor can decide when it's time for you to begin Pap testing and how often you should have the test.

In general, doctors recommend beginning Pap testing at age 21.

How often should Pap smear be repeated?

Doctors generally recommend repeating Pap testing every 3 years for women ages 21-65.

Women age 30 and older can consider Pap testing every 5 years if the procedure is combined with testing for HPV.

If you have certain risk factors, your doctor may recommend more-frequent Pap smears, regardless of your age. These risk factors include:

• A diagnosis of cervical cancer or a Pap smear that showed precancerous cells
• Exposure to diethylstilbestrol (DES) before birth
• HIV infection
• Weakened immune system due to organ transplant, chemotherapy or chronic corticosteroid use

You and your doctor can discuss the benefits and risks of Pap smears and decide what's best for you based on your risk factors.

Who can consider stopping Pap smears?

In certain situations a woman and her doctor may decide to end Pap testing, such as:

• After a total hysterectomy. After a total hysterectomy — surgical removal of the uterus including the cervix — ask your doctor if you need to continue having Pap smears.
  If your hysterectomy was performed for a noncancerous condition, such as uterine fibroids, you may be able to discontinue routine Pap smears.
  But if your hysterectomy was for a precancerous or cancerous condition of the cervix, your doctor may recommend continuing routine Pap testing.
• Older age. Doctors generally agree that women can consider stopping routine Pap testing at age 65 if their previous tests for cervical cancer have been negative.
  Discuss your options with your doctor and together you can decide what's best for you based on your risk factors. If you're sexually active with multiple partners, your doctor may recommend continuing Pap testing.

Pelvic pain is pain in the lowest part of your abdomen and pelvis. In women, pelvic pain might refer to symptoms arising from the reproductive, urinary or digestive systems, or from musculoskeletal sources.

Depending on its source, pelvic pain can be dull or sharp; it might be constant or off and on (intermittent); and it might be mild, moderate or severe. Pelvic pain can sometimes radiate to your lower back, buttocks or thighs. Sometimes, you might notice pelvic pain only at certain times, such as when you urinate or during sexual activity.

Pelvic pain can occur suddenly, sharply and briefly (acute) or over the long term (chronic). Chronic pelvic pain refers to any constant or intermittent pelvic pain that has been present for six months or more.

Causes

Several types of diseases and conditions can cause pelvic pain. Chronic pelvic pain can result from more than one condition.

Pelvic pain can arise from your digestive, reproductive or urinary system. Recently, doctors have recognized that some pelvic pain, particularly chronic pelvic pain, can also arise from muscles and connective tissue (ligaments) in the structures of the pelvic floor. Occasionally, pelvic pain might be caused by irritation of nerves in the pelvis.

Female reproductive system

Pelvic pain arising from the female reproductive system might be caused by conditions such as:

• Pregnancy-related conditions
• Endometriosis
• Dysmenorrhea
• Miscarriage (before the 20th week) or intrauterine fetal death
• Ovulation pain
• Ovarian cysts
• Pelvic inflammatory disease (PID)
• Salpingitis (inflammation of the fallopian tubes)
• Uterine fibroids
• Vulvodynia

Other causes in women or men

Examples of other possible causes of pelvic pain — in women or men — include:

• Crohn's disease
• Chronic constipation
• Colon cancer
• Intestinal obstruction
• Enlarged spleen (splenomegaly)
• Fibromyalgia
• Inguinal hernia
• Interstitial cystitis (also called painful bladder syndrome)
• Kidney stones
• Past physical or sexual abuse
• Pelvic floor muscle spasms
• Prostatitis
• Psychological factors
• Ulcerative colitis

When to see a doctor

If you suddenly develop severe pelvic pain, it might be a medical emergency and you should seek medical attention promptly. Be sure to get pelvic pain checked by your doctor if it's new, if it disrupts your daily life, or if it has gotten worse over time.

Read about diagnosis, treatment and more. 

When the muscles and ligaments supporting a woman's pelvic organs weaken, the pelvic organs can drop lower in the pelvis, creating a bulge in the vagina (prolapse). Women most commonly develop pelvic organ prolapse years after childbirth, after a hysterectomy or after menopause. If you have symptoms, such as a feeling of pressure in your pelvic area, see your health care provider.

Premenstrual syndrome (PMS) has a wide variety of symptoms, including mood swings, tender breasts, food cravings, fatigue, irritability and depression. It's estimated that as many as 3 of every 4 menstruating women have experienced some form of premenstrual syndrome.

Symptoms tend to recur in a predictable pattern. But the physical and emotional changes you experience with premenstrual syndrome may vary from just slightly noticeable all the way to intense.

Still, you don't have to let these problems control your life. Treatments and lifestyle adjustments can help you reduce or manage the signs and symptoms of premenstrual syndrome.

Symptoms

The list of potential signs and symptoms for premenstrual syndrome is long, but most women only experience a few of these problems.

Emotional and behavioral symptoms

• Tension or anxiety
• Depressed mood
• Crying spells
• Mood swings and irritability or anger
• Appetite changes and food cravings
• Trouble falling asleep (insomnia)
• Social withdrawal
• Poor concentration

Physical signs and symptoms

• Joint or muscle pain
• Headache
• Fatigue
• Weight gain related to fluid retention
• Abdominal bloating
• Breast tenderness
• Acne flare-ups
• Constipation or diarrhea

For some, the physical pain and emotional stress are severe enough to affect their daily lives. Regardless of symptom severity, the signs and symptoms generally disappear within four days of the start of the menstrual period for most women.

But a small number of women with premenstrual syndrome have disabling symptoms every month. This form of PMS is called premenstrual dysphoric disorder (PMDD).

PMDD signs and symptoms include depression, mood swings, anger, anxiety, feeling overwhelmed, difficulty concentrating, irritability and tension.

When to see a doctor

If you haven't been able to manage your premenstrual syndrome with lifestyle changes and the symptoms of PMS are affecting your health and daily activities, see your doctor.

Causes

Exactly what causes premenstrual syndrome is unknown, but several factors may contribute to the condition:

• Cyclic changes in hormones. Signs and symptoms of premenstrual syndrome change with hormonal fluctuations and disappear with pregnancy and menopause.
• Chemical changes in the brain. Fluctuations of serotonin, a brain chemical (neurotransmitter) that is thought to play a crucial role in mood states, could trigger PMS symptoms. Insufficient amounts of serotonin may contribute to premenstrual depression, as well as to fatigue, food cravings and sleep problems.
• Depression. Some women with severe premenstrual syndrome have undiagnosed depression, though depression alone does not cause all of the symptoms.

Urinary incontinence — the loss of bladder control — is a common and often embarrassing problem. The severity ranges from occasionally leaking urine when you cough or sneeze to having an urge to urinate that's so sudden and strong you don't get to a toilet in time.

Though it occurs more often as people get older, urinary incontinence isn't an inevitable consequence of aging. If urinary incontinence affects your daily activities, don't hesitate to see your doctor. For most people, simple lifestyle changes or medical treatment can ease discomfort or stop urinary incontinence.

Symptoms

Many people experience occasional, minor leaks of urine. Others may lose small to moderate amounts of urine more frequently.

Types of urinary incontinence include:

• Stress incontinence. Urine leaks when you exert pressure on your bladder by coughing, sneezing, laughing, exercising or lifting something heavy.
• Urge incontinence. You have a sudden, intense urge to urinate followed by an involuntary loss of urine. You may need to urinate often, including throughout the night. Urge incontinence may be caused by a minor condition, such as infection, or a more-severe condition such as a neurologic disorder or diabetes.
• Overflow incontinence. You experience frequent or constant dribbling of urine due to a bladder that doesn't empty completely.
• Functional incontinence. A physical or mental impairment keeps you from making it to the toilet in time. For example, if you have severe arthritis, you may not be able to unbutton your pants quickly enough.
• Mixed incontinence. You experience more than one type of urinary incontinence.

When to see a doctor

You may feel uncomfortable discussing incontinence with your doctor. But if incontinence is frequent or is affecting your quality of life, it's important to seek medical advice because urinary incontinence may:

• Indicate a more-serious underlying condition
• Cause you to restrict your activities and limit your social interactions
• Increase the risk of falls in older adults as they rush to the toilet

Causes

Urinary incontinence isn't a disease, it's a symptom. It can be caused by everyday habits, underlying medical conditions or physical problems. A thorough evaluation by your doctor can help determine what's behind your incontinence.

Temporary urinary incontinence

Certain drinks, foods and medications may act as diuretics — stimulating your bladder and increasing your volume of urine. They include:

• Alcohol
• Caffeine
• Carbonated drinks and sparkling water
• Artificial sweeteners
• Chocolate
• Chili peppers
• Foods that are high in spice, sugar or acid, especially citrus fruits
• Heart and blood pressure medications, sedatives, and muscle relaxants
• Large doses of vitamin C

Urinary incontinence may also be caused by an easily treatable medical condition, such as:

• Urinary tract infection. Infections can irritate your bladder, causing you to have strong urges to urinate, and sometimes incontinence.
• Constipation. The rectum is located near the bladder and shares many of the same nerves. Hard, compacted stool in your rectum causes these nerves to be overactive and increase urinary frequency.

Persistent urinary incontinence

Urinary incontinence can also be a persistent condition caused by underlying physical problems or changes, including:

• Pregnancy. Hormonal changes and the increased weight of the fetus can lead to stress incontinence.
• Childbirth. Vaginal delivery can weaken muscles needed for bladder control and also damage bladder nerves and supportive tissue, leading to a dropped (prolapsed) pelvic floor. With prolapse, the bladder, uterus, rectum or small intestine can get pushed down from the usual position and protrude into the vagina. Such protrusions can be associated with incontinence.
• Changes with age. Aging of the bladder muscle can decrease the bladder's capacity to store urine. Also, involuntary bladder contractions become more frequent as you get older.
• Menopause. After menopause women produce less estrogen, a hormone that helps keep the lining of the bladder and urethra healthy. Deterioration of these tissues can aggravate incontinence.
• Hysterectomy. In women, the bladder and uterus are supported by many of the same muscles and ligaments. Any surgery that involves a woman's reproductive system, including removal of the uterus, may damage the supporting pelvic floor muscles, which can lead to incontinence.
• Enlarged prostate. Especially in older men, incontinence often stems from enlargement of the prostate gland, a condition known as benign prostatic hyperplasia.
• Prostate cancer. In men, stress incontinence or urge incontinence can be associated with untreated prostate cancer. But more often, incontinence is a side effect of treatments for prostate cancer.
• Obstruction. A tumor anywhere along your urinary tract can block the normal flow of urine, leading to overflow incontinence. Urinary stones — hard, stone-like masses that form in the bladder — sometimes cause urine leakage.
• Neurological disorders. Multiple sclerosis, Parkinson's disease, a stroke, a brain tumor or a spinal injury can interfere with nerve signals involved in bladder control, causing urinary incontinence.

Risk factors

Factors that increase your risk of developing urinary incontinence include:

• Gender. Women are more likely to have stress incontinence. Pregnancy, childbirth, menopause and normal female anatomy account for this difference. However, men with prostate gland problems are at increased risk of urge and overflow incontinence.
• Age. As you get older, the muscles in your bladder and urethra lose some of their strength. Changes with age reduce how much your bladder can hold and increase the chances of involuntary urine release.
• Being overweight. Extra weight increases pressure on your bladder and surrounding muscles, which weakens them and allows urine to leak out when you cough or sneeze.
• Smoking. Tobacco use may increase your risk of urinary incontinence.
• Family history. If a close family member has urinary incontinence, especially urge incontinence, your risk of developing the condition is higher.
• Other diseases. Neurological disease or diabetes may increase your risk of incontinence.

Complications

Complications of chronic urinary incontinence include:

• Skin problems. Rashes, skin infections and sores can develop from constantly wet skin.
• Urinary tract infections. Incontinence increases your risk of repeated urinary tract infections.
• Impacts on your personal life. Urinary incontinence can affect your social, work and personal relationships.

Prevention

Urinary incontinence isn't always preventable. However, to help decrease your risk:

• Maintain a healthy weight
• Practice pelvic floor exercises
• Avoid bladder irritants, such as caffeine, alcohol and acidic foods
• Eat more fiber, which can prevent constipation, a cause of urinary incontinence
• Don't smoke, or seek help to quit smoking

Uterine fibroids are noncancerous growths of the uterus that often appear during childbearing years. Also called leiomyomas (lie-o-my-O-muhs) or myomas, uterine fibroids aren't associated with an increased risk of uterine cancer and almost never develop into cancer.

Fibroids range in size from seedlings, undetectable by the human eye, to bulky masses that can distort and enlarge the uterus. You can have a single fibroid or multiple ones. In extreme cases, multiple fibroids can expand the uterus so much that it reaches the rib cage.

Many women have uterine fibroids sometime during their lives. But most women don't know they have uterine fibroids because they often cause no symptoms. Your doctor may discover fibroids incidentally during a pelvic exam or prenatal ultrasound.

Symptoms

Many women who have fibroids don't have any symptoms. In those that do, symptoms can be influenced by the location, size and number of fibroids. In women who have symptoms, the most common symptoms of uterine fibroids include:

• Heavy menstrual bleeding
• Menstrual periods lasting more than a week
• Pelvic pressure or pain
• Frequent urination
• Difficulty emptying the bladder
• Constipation
• Backache or leg pains
• Rarely, a fibroid can cause acute pain when it outgrows its blood supply, and begins to die.

Fibroids are generally classified by their location. Intramural fibroids grow within the muscular uterine wall. Submucosal fibroids bulge into the uterine cavity. Subserosal fibroids project to the outside of the uterus.

When to see a doctor

See your doctor if you have:

• Pelvic pain that doesn't go away
• Overly heavy, prolonged or painful periods
• Spotting or bleeding between periods
• Difficulty emptying your bladder
• Seek prompt medical care if you have severe vaginal bleeding or sharp pelvic pain that comes on suddenly.

Causes

Doctors don't know the cause of uterine fibroids, but research and clinical experience point to these factors:

• Genetic changes. Many fibroids contain changes in genes that differ from those in normal uterine muscle cells.
• Hormones. Estrogen and progesterone, two hormones that stimulate development of the uterine lining during each menstrual cycle in preparation for pregnancy, appear to promote the growth of fibroids. Fibroids contain more estrogen and progesterone receptors than normal uterine muscle cells do. Fibroids tend to shrink after menopause due to a decrease in hormone production.
• Other growth factors. Substances that help the body maintain tissues, such as insulin-like growth factor, may affect fibroid growth.

Doctors believe that uterine fibroids develop from a stem cell in the smooth muscular tissue of the uterus (myometrium). A single cell divides repeatedly, eventually creating a firm, rubbery mass distinct from nearby tissue.

The growth patterns of uterine fibroids vary — they may grow slowly or rapidly, or they may remain the same size. Some fibroids go through growth spurts, and some may shrink on their own. Many fibroids that have been present during pregnancy shrink or disappear after pregnancy, as the uterus goes back to a normal size.

Risk factors

There are few known risk factors for uterine fibroids, other than being a woman of reproductive age. Other factors that can have an impact on fibroid development include:

• Heredity. If your mother or sister had fibroids, you're at increased risk of developing them.
• Race. Black women are more likely to have fibroids than women of other racial groups. In addition, black women have fibroids at younger ages, and they're also likely to have more or larger fibroids.
• Environmental factors. Onset of menstruation at an early age; use of birth control; obesity; a vitamin D deficiency; having a diet higher in red meat and lower in green vegetables, fruit and dairy; and drinking alcohol, including beer, appear to increase your risk of developing fibroids.

Complications

Although uterine fibroids usually aren't dangerous, they can cause discomfort and may lead to complications such as anemia from heavy blood loss.

Pregnancy and fibroids

Fibroids usually don't interfere with getting pregnant. However, it's possible that fibroids — especially submucosal fibroids — could cause infertility or pregnancy loss. Fibroids may also raise the risk of certain pregnancy complications, such as placental abruption, fetal growth restriction and preterm delivery.

Prevention

Although researchers continue to study the causes of fibroid tumors, little scientific evidence is available on how to prevent them. Preventing uterine fibroids may not be possible, but only a small percentage of these tumors require treatment.

But, by making healthy lifestyle choices, such as maintaining a normal weight and eating fruits and vegetables, you may be able to decrease your fibroid risk.
