Endometriosis
A chronic disease where uterine-like tissue grows outside the uterus.
Endometriosis is a disease where tissue resembling the uterine lining grows in other parts of the body, most commonly near the uterus on the ovaries, fallopian tubes, or pelvic lining, but also potentially on the bowel, bladder, lungs, or skin. It affects about ten percent of reproductive-age women worldwide, totaling nearly 200 million individuals. Symptoms usually begin in adolescence or the early twenties and tend to ease after menopause as estrogen levels drop. The condition varies widely: some people have no symptoms, while others experience debilitating pain. Common complaints include pelvic pain, heavy and painful periods, pain during bowel movements or urination, painful sex, fatigue, and infertility. The pain often follows a cyclical pattern, intensifying during menstruation, and can feel like cramping or stabbing in the lower abdomen, sometimes radiating to the lower back. Beyond physical effects, endometriosis can impact mental health and social life. The exact cause is unknown, but possible factors include retrograde menstrual flow, genetics, hormones, and immune system issues. Diagnosis is often presumed from symptoms and imaging, with laparoscopy and biopsy providing confirmation. Other conditions with similar symptoms include adenomyosis, uterine fibroids, irritable bowel syndrome, and bladder pain syndrome. On average, diagnosis takes five to twelve years from symptom onset, and many women report being told their symptoms are trivial or normal. While there is no cure, treatments include hormonal therapies, pain medication, and surgery. First-line options often combine a hormonal IUD or continuous birth control pills with an NSAID like naproxen. Surgical removal of lesions may help when other treatments fail or infertility is involved, though endometriosis can return after surgery in a substantial minority of cases.

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
What is Endometriosis known for?
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.
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.
