Endometriosis in teenagers

Endometriosis is tissue similar to the womb lining growing outside the womb. In teenagers, symptoms may include severe or worsening period pain, heavy or prolonged bleeding, pelvic pain between periods, bowel or bladder discomfort, tiredness, nausea, or pain during sex. Missing lessons, avoiding activities, or needing repeated pain relief are useful clues to share with a clinician. Painful periods are common, but pain that disrupts ordinary life should not be dismissed as something a teenager must simply endure.

A teenager can keep a private symptom diary and bring a trusted adult to an appointment if that feels comfortable. Note cycle dates, bleeding, pain, digestive or urinary changes, and the effect on school and sleep. A clinician may discuss an examination, symptom treatment, and whether referral is appropriate. Treatment choices should reflect age, general health, preferences, and future pregnancy plans. More background is available on [Endometriosis](/conditions/endometriosis/).

Book an appointment when pain repeatedly interrupts school, sport, sleep, or friendships, or when bleeding is difficult to manage. Seek urgent help for severe sudden pain, fainting, fever, repeated vomiting, or possible pregnancy with pain or bleeding. A parent, school nurse, or another trusted adult can help a teenager reach care.

Could these symptoms be endometriosis or another cause of painful periods? What can I safely use for pain? Do I need specialist assessment? How can treatment protect school attendance and daily activities?
