Cells that are like the cells that line the inside of your uterus sometimes grow on the outside of the uterus. This is called endometriosis. These clumps of cells can cause pain and problems with your periods. They can become inflamed and may bleed. Scar tissue that forms over time can make it difficult to get pregnant.
Medicines and sometimes surgery can relieve pain and may help you get pregnant.
Endometriosis (say "en-doh-mee-tree-OH-sus") occurs when cells that are like the cells that line the inside of your uterus grow outside of your uterus. These cells form growths that often attach to the ovaries or other organs, and they may bleed during your period and cause pain. They may also make it hard for you to get pregnant.
Endometriosis can be treated with medicines or with surgery.
Your uterus is lined with tissue called endometrium. When you have endometriosis, clumps of similar tissue (called implants) form outside your uterus. The implants can be painful. Sometimes they form scar tissue or fluid-filled sacs (cysts). Scar tissue may make it hard to get pregnant.
The most common symptoms are pain, bleeding, and trouble getting pregnant. You may have pain in your lower belly, rectum or vagina, or lower back. And you may have heavy periods, bleeding between periods, bleeding after sex, or blood in your urine or stool. Symptoms often are most severe before and during your menstrual period.
Treatment depends on how much pain you have and whether you want to get pregnant. Treatments include:
A hysterectomy and oophorectomy (removal of the uterus and ovaries) are sometimes used as a last resort for severe pain.
If you're close to menopause, you may consider treatment with medicines rather than surgery. Endometriosis usually stops causing problems when you stop having periods.
Hormone therapy (HT) can often relieve the symptoms of endometriosis. It can be used to reduce pain and bleeding. It may also shrink endometriosis growths (implants) and keep them from spreading.
HT prevents pregnancy, so it's not a good option if you want to get pregnant soon.
Estrogen-progestin therapy plus a nonsteroidal anti-inflammatory drug (NSAID) are often used if symptoms are mild to moderate. If you have severe symptoms, or if estrogen-progestin therapy and NSAIDs don't relieve your symptoms, you may have other HT options. Talk to your doctor about the benefits and risks of the different types of HT.
You might consider taking HT if:
You might decide not to take HT if:
Your doctor can help you weigh the pros and cons of HT so you can decide what's right for you.
Endometriosis cannot be prevented. This is in part because the cause is poorly understood. But long-term use of birth control hormones (patch, pills, or ring) may prevent endometriosis from becoming worse.
Your doctor will ask questions about your symptoms, periods, past health, and family medical history. You may also have a pelvic exam. And you may have imaging tests, such as a pelvic ultrasound or MRI. But to find out for sure if you have endometriosis, a surgery called laparoscopy is often used.
Any of the following health professionals can evaluate endometriosis and help you manage the pain:
If your case is complicated or your main problem is infertility, you may be referred to a:
For diagnosis with laparoscopy or for surgical treatment, you may be referred to a gynecologist.
There are things you can try at home to ease the pain of endometriosis. Applying heat to your lower belly may relieve pelvic pain. To relieve back pressure, try placing a pillow under your knees while you lie on your back. Getting regular exercise may also help relieve pain.
Surgery may be recommended when:
Surgery choices include:
Your risk of endometriosis is higher if:
Endometriosis may cause infertility or ovarian problems.
Experts don't fully understand how endometriosis causes infertility. It could be that:
A common complication of endometriosis is the development of a cyst on an ovary. This blood-filled growth is called an ovarian endometrioma or an endometrial cyst. The symptoms of an ovarian cyst may be the same as those of endometriosis.
Also, ovarian cancer risk is slightly higher if you have endometriosis.
Experts aren't sure what causes endometriosis. Problems with reproductive organs may cause endometrial cells to go up through the fallopian tubes and into the belly. And your immune system may not kill these cells outside the uterus like it should. These cells might be carried through the body by blood or lymph fluid.
Endometriosis (say "en-doh-mee-tree-OH-sus") occurs when cells that are like the cells that line the inside of your uterus grow outside of your uterus. These cells form clumps of tissue called implants. They usually grow on the ovaries, the fallopian tubes, the outer wall of the uterus, the intestines, or other organs in the belly. In rare cases, they spread to areas beyond the belly.
Endometriosis usually isn't dangerous. But it can cause pain and other problems.
