Endometriosis
A chronic disease where uterine-like tissue grows outside the uterus.
Endometriosis is a disease in which tissue similar to the endometrium—the lining of the uterus—grows elsewhere in the body, most often near the uterus but also on the bowel, bladder, lungs, or skin.

Lore & Background
Endometriosis occurs when endometrium-like tissue forms lesions or implants outside the uterus. These lesions can be classified into subtypes: superficial peritoneal endometriosis (small lesions on the lining of the abdominal cavity), deep infiltrating endometriosis (lesions growing more than 5 mm beneath the peritoneal surface, often into organ muscle layers), endometriomas (cysts in the ovaries, sometimes called 'chocolate cysts'), and extrapelvic endometriosis (rare sites such as the lungs or diaphragm). Symptoms vary widely; some individuals have none, while others experience debilitating pain, heavy bleeding, and infertility. The pain is only weakly related to the extent of the disease—those with limited endometriosis may have severe pain, while those with extensive disease may have few symptoms.
Reader's Guide
Its impact extends beyond physical symptoms to mental health and social life, with depression and anxiety occurring at rates similar to other chronic pain conditions. Diagnosis is often delayed by 5–12 years, and many women report being told their symptoms are trivial or normal. While there is no cure, treatments include hormonal therapies (such as hormonal IUDs or birth control pills), NSAIDs, and surgical removal of lesions. However, endometriosis returns after surgery in a substantial minority of cases. The disease is associated with increased risks of pregnancy complications, cardiovascular disease, and certain cancers. Genetic factors account for about half the risk, with 80 genetic loci linked to the condition. Endometriosis remains an area of active research, with its exact cause unknown.
Did You Know?
- On average, it takes 5–12 years from the start of symptoms to receive a diagnosis.
- Endometriomas are cysts in the ovaries filled with old menstrual blood, giving them the name 'chocolate cysts'.
- Women with endometriosis have a three-fold increased risk of placenta previa and nearly 50% higher risk of preterm delivery.
Frequently Asked Questions
Who is Endometriosis?
Endometriosis is a chronic condition in which tissue resembling the uterine lining takes up residence outside the uterus, colonizing areas such as the bowel, bladder, lungs, or skin. It is not a malignancy; rather, it is misplaced endometrial-like tissue that keeps cycling in locations where it does not belong.
What are Endometriosis's powers or role?
Its signature 'abilities' include generating severe pelvic pain, disrupting menstrual cycles, causing pain during intercourse, and impairing fertility. It can also produce ovarian cysts called endometriomas, burrow deeply into surrounding organs, and leave sufferers with persistent fatigue.
How does Endometriosis's story end?
There is no definitive finale—Endometriosis is a lifelong, chronic condition with no known permanent cure. Management generally relies on hormonal therapy, surgical excision of lesions, or ongoing pain control, and symptoms frequently persist or recur across a person's lifetime.
Who does Endometriosis typically target, and when does it debut?
It almost exclusively affects people who have a uterus, with onset commonly appearing during adolescence or the early twenties. It is also frequently linked to comorbid conditions such as irritable bowel syndrome, autoimmune disorders, and elevated risks of ovarian, thyroid, and cardiovascular disease.
