Facts about Fibroids

Uterine fibroids are tumors or lumps made of muscle cells and other tissue that grow within the wall of the uterus. Fibroids may grow as a single tumor or in clusters.

A single fibroid can be less than one inch in size or can grow to eight inches across or more. A bunch or cluster of fibroids can also vary in size.

Where do uterine fibroids grow?

Most fibroids grow within the wall of the uterus. Health care providers put fibroids into three groups based on where they grow:

•Submucosal (pronounced sub-myou-co-sul) fibroids grow just underneath the uterine lining.
•Intramural (pronounced in-tra-myur-ul) fibroids grow in between the muscles of the uterus.
•Subserosal (pronounced sub-sir-oh-sul) fibroids grow on the outside of the uterus.
Some fibroids grow on stalks (also called peduncles, pronounced ped-uncles) that grow out from the surface of the uterus, or into the cavity of the uterus.

What are the symptoms of uterine fibroids?

Many women don’t feel any symptoms with uterine fibroids. But fibroids can cause the following symptoms:

•Heavy bleeding or painful periods
•Bleeding between periods
•Feeling “full” in the lower abdomen—sometimes called “pelvic pressure”
•Urinating often (results from a fibroid pressing on the bladder)
•Pain during sex
•Lower back pain
•Reproductive problems, such as infertility, multiple miscarriages, and early onset of labor during pregnancy

What causes uterine fibroids?

Currently, we know little about what causes uterine fibroids. Scientists have a number of theories, but none of these ideas explains fibroids completely. Most likely, fibroids are the end result of many factors interacting with each other. These factors could be genetic, hormonal, environmental, or a combination of all three. Once we know the cause or causes of fibroids, our efforts to find a cure or even prevent fibroids will move ahead more quickly.

Does having uterine fibroids mean that a woman will be infertile or unable to have children?

In some cases, fibroids can prevent a woman from getting pregnant through natural methods. However, advances in treatments for fibroids and infertility have greatly improved the chances for a woman to get pregnant, even if she has uterine fibroids.

Researchers are still looking into what role, if any, uterine fibroids play in infertility. Currently, though, there are few answers. One study’s results suggest that only submucosal fibroids have a negative impact on fertility (Pritts 2001), but these results are not yet confirmed. The relationship between fibroids and infertility remains a very active research area.

Does having uterine fibroids mean a woman will need a hysterectomy (removing the uterus)?

Hysterectomy is not the best option for every woman with uterine fibroids. If a woman wants to have children, then she would want to avoid this treatment. Likewise, if a woman isn’t showing symptoms of uterine fibroids, or her fibroids are small, she may have better results from pain medications or hormone treatments. Doctors are also exploring less-invasive surgical treatments for fibroids that save the uterus. See the What are the treatments for uterine fibroids? section of this fact sheet for more information about less-invasive treatments.

In some cases, though, a hysterectomy is the best method of treatment. If you have uterine fibroids and are thinking about having a hysterectomy, make sure you talk over all features of the surgery with your doctor and your family. Having a hysterectomy means that you will no longer be able to have children. This process cannot be reversed, so be certain about your choice before having the surgery.

Keep in mind that the physical scars of the procedure may heal quickly, but some of the effects of hysterectomy are long-lasting. You may want to talk to women who have had the procedure before you decide to have your surgery. Many health care centers, women’s clinics, and hospitals offer support groups for women who have had, or are in the process of having a hysterectomy.

Who gets uterine fibroids?

Most of the time, fibroids grow in women of childbearing age. Research studies estimate that doctors diagnose up to 30 percent of women of childbearing age with uterine fibroids; but, because some women show no symptoms of fibroids, as many as 77 percent of women of childbearing age could have the condition, without knowing it. We don’t know exactly how many new cases of fibroids occur in a year, nor do we know how many women have fibroids at any one time.

There have also been reports of rare cases in which young girls who have not yet started their periods (pre-pubertal) had small fibroids.

Researchers now recognize several risk factors for uterine fibroids.

•Current statistics place African-American women at three-to-five times greater risk than white women for fibroids.
•Women who are overweight or obese for their height (based on body mass index or BMI*) are also at slightly higher risk for fibroids than women who are average weight for their height.
•Women who have given birth appear to be at lower risk for uterine fibroids.
But, because we don’t know what causes fibroids, we also don’t know what increases or reduces their growth.

How do I know that I have uterine fibroids?

Unless you start to have symptoms, you probably won’t know that you have uterine fibroids. Sometimes, health care providers find fibroids during a routine gynecological exam.

Headache

Problems with Headaches

Headaches

There are four types of headache:  vascular, muscle contraction (tension), traction, and inflammatory.  The most common type of vascular headache is migraine. Migraine headaches are usually characterized by severe pain on one or both sides of the head, an upset stomach, and, at times, disturbed vision.   Women are more likely than men to have migraine headaches.    After migraine, the most common type of vascular headache is the toxic headache produced by fever.  Other kinds of vascular headaches include “cluster” headaches, which cause repeated episodes of intense pain, and headaches resulting from high blood pressure.  Muscle contraction headaches appear to involve the tightening or tensing of facial and neck muscles.  Traction and inflammatory headaches are symptoms of other disorders, ranging from stroke to sinus infection.  Like other types of pain, headaches can serve as warning signals of more serious disorders. This is particularly true for headaches caused by inflammation, including those related to meningitis as well as those resulting from diseases of the sinuses, spine, neck, ears, and teeth.

Is there any treatment?

When headaches occur three or more times a month, preventive treatment is usually recommended.  Drug therapy, biofeedback training, stress reduction, and elimination of certain foods from the diet are the most common methods of preventing and controlling migraine and other vascular headaches. Regular exercise, such as swimming or vigorous walking, can also reduce the frequency and severity of migraine headaches.  Drug therapy for migraine is often combined with biofeedback and relaxation training.  One of the most commonly used drugs for the relief of migraine symptoms is sumatriptan.  Drugs used to prevent migraine also include methysergide maleate, which counteracts blood vessel constriction; propranolol hydrochloride, which also reduces the frequency and severity of migraine headaches; ergotamine tartrate, a vasoconstrictor that helps counteract the painful dilation stage of the headache; amitriptyline, an antidepressant; valproic acid, an anticonvulsant; and verapamil, a calcium channel blocker.

What is the prognosis?

Not all headaches require medical attention. But some types of headache are signals of more serious disorders and call for prompt medical care. These include: sudden, severe headache or sudden headache associated with a stiff neck; headaches associated with fever, convulsions, or accompanied by confusion or loss of consciousness; headaches following a blow to the head, or associated with pain in the eye or ear; persistent headache in a person who was previously headache free; and recurring headache in children.  Migraine headaches may last a day or more and can strike as often as several times a week or as rarely as once every few years.

What research is being done?

The National Institute of Neurological Disorders and Stroke (NINDS) conducts research relating to headaches at its laboratories at the National Institutes of Health (NIH), and supports additional research through grants to major medical institutions across the country.  NINDS also supports and conducts studies to improve the diagnosis of headaches and to find ways to prevent them.
