This tutorial walks you through everything you need to know about endometriosis. We explain it in plain language, step by step, so whether you are a student, a patient, or simply curious, you will come away with a solid understanding.

We cover what it is, why it matters, how it is diagnosed, and what you can do about it. Key facts are called out along the way.

What is endometriosis? The uterus, or womb, is the place where a fetus grows during pregnancy. The uterus is lined with tissue (endometrium). Endometriosis is a disease in which tissue like the lining of the uterus grows in other places in your body. These patches of tissue are called “implants,” “nodules,” or “lesions.” They are most often found:

On or under the ovaries

On the fallopian tubes, which carry eggs from the ovaries to the uterus

Behind the uterus

On the tissues that hold the uterus in place

On the bowels or bladder

In rare cases, the tissue may grow on your lungs or in other parts of your body.

What causes endometriosis? Researchers don’t know what causes endometriosis.

Who is at risk for endometriosis? Endometriosis can affect anyone who menstruates. Certain factors can raise or lower your risk of getting it.

You are at higher risk if:

You have a mother, sister, or daughter with endometriosis

Your period started before age 11

Your monthly cycles are short (less than 27 days)

Your menstrual cycles are heavy and last more than 7 days

You have a lower risk if:

You have been pregnant before

Your periods started late in adolescence

You breastfeed your babies

What are the symptoms of endometriosis? The main symptoms of endometriosis are:

Pelvic pain, which often happens during your period

Infertility

Other possible symptoms include:

Painful menstrual cramps, which may get worse over time

Pain during or after sex

Pain in the intestine or lower abdomen

Pain with bowel movements (pooping) or urination (peeing), usually during your period

Heavy periods

Spotting or bleeding between periods

Digestive or gastrointestinal symptoms

Fatigue or lack of energy

How is endometriosis diagnosed? Surgery is the only way to know for sure that you have endometriosis. First, however, your health care provider will ask about your symptoms and medical history. You will have a pelvic exam and may have some imaging tests.

The most common surgery to diagnose endometriosis is a laparoscopy. This is a type of surgery that uses a laparoscope, a thin tube with a camera and light. The surgeon inserts the laparoscope through a small cut in the skin near your belly button. Your provider can make a diagnosis based on how the patches of endometriosis look. They may also do a biopsy to get a tissue sample.

What are the treatments for endometriosis? There is no cure for endometriosis, but there are treatments for the symptoms. Your provider will work with you to decide which treatments would be best for you.

Treatments for endometriosis pain include:

Pain relievers, including nonsteroidal anti-inflammatory drugs (NSAIDS) such as ibuprofen and a prescription medicine specifically for endometriosis. Providers may sometimes prescribe opioids for severe pain.

Hormone therapy, which stops the ovaries from making hormones. This may slow the growth of the endometrial tissue and may stop new areas from growing. Types of hormone therapy include:

	Birth control pills.

	Progestin therapy.

	Gonadotropin-releasing hormone (GnRH) medicines (GnRH agonists and antagonists).  These medicines cause a temporary menopause.  After your stop taking the medicines, your menstrual periods will start again, and pregnancy is possible.

Surgical treatments for severe pain, including procedures to remove the endometriosis patches or cut some nerves in the pelvis. The surgery may be a laparoscopy or major surgery.

Treatments for infertility caused by endometriosis include:

Laparoscopy to remove the endometriosis patches

In vitro fertilization
