What Is Endometriosis?


Endometriosis is a painful condition where tissue similar to the lining of the uterus grows outside it—most often on the ovaries, fallopian tubes, or pelvic lining. In some cases, it can spread beyond the pelvic area to the bowel, diaphragm or lung. This tissue causes inflammation, scar tissue, sometimes causing organs in the pelvis to stick together. Endometriosis often leads to significant pain, particularly during menstrual periods, and may affect fertility. However, with proper treatment, symptoms and complications can be effectively managed.

Pathophysiology

Endometriosis occurs when endometrial-like tissue (tissue that behaves like the lining of the uterus) implants and grows outside the uterine cavity — most commonly on the ovaries, fallopian tubes, peritoneum, bladder, and bowel. These implants respond to hormonal changes throughout the menstrual cycle, leading to cyclical inflammation, bleeding, and scarring.

Symptoms

Common symptoms include:

  • Pelvic pain (especially before and during menstruation)

  • Pain during or after sex (dyspareunia)

  • Pain during bowel movements or urination

  • Heavy or irregular menstrual bleeding

  • Fatigue, bloating, or nausea

  • Infertility (endometriosis is found in up to 50% of women with fertility issues)

Pain severity doesn’t always correlate with the extent of disease — small lesions can cause severe pain, and vice versa.

Diagnosis

  • The average time from symptom onset to proper diagnosis is 7-10 years. Early detection can lead to better disease management and improved quality of life.

  • Laparoscopy (minimally invasive surgery) remains the gold standard for diagnosis.

  • Imaging tools like ultrasound or MRI can suggest endometriomas or deep infiltrating endometriosis but are not definitive and often miss small lesions.

Treatment Options

Treatment depends on symptom severity, age, and fertility goals:

  • Medications: Hormonal medications, anti-inflammatory medications.

  • Surgery: Laparoscopic removal of endometrial implants.

  • Pain management: NSAIDs, nerve blocks, or complementary therapies (acupuncture, physical therapy).

  • Fertility management: Assisted reproductive technologies like IVF if conception is difficult.

Outlook

Endometriosis is chronic and can recur even after treatment, but symptoms can be effectively managed through a multimodal plan involving hormonal control, surgical intervention, and supportive therapies. Early diagnosis and personalized care can significantly improve quality of life.
