Endometriosis: symptoms, diagnosis and a pain diary
Period pain that interrupts school, work or everyday activities deserves assessment. Endometriosis is one possible explanation, not the only one. A diary can help communicate symptoms, but it cannot establish a diagnosis.
What endometriosis means
Endometriosis involves tissue similar to the uterine lining outside the uterus. Symptoms can include pelvic pain, painful sex, bowel or bladder symptoms and difficulty conceiving. Experiences vary, and symptoms are not always limited to menstruation.
How it is investigated
A clinician asks about pain and its effect on daily life. Examination, ultrasound, MRI or laparoscopy may be considered. WHO notes that surgical confirmation is not always required before treatment begins; symptoms and imaging can inform a clinical diagnosis.
Discussing treatment options
The plan depends on symptoms, treatment tolerance and pregnancy intentions. Pain relief, hormonal treatment and surgery may be options, but none promises a universal cure. Persistent symptoms warrant a review and discussion of specialist or multidisciplinary pain support.
What to put in a diary
Record cycle day, pain location and duration, effects on sleep and activities, bleeding and medicines used. Note pain with urination, bowel movements or sex. Describing what you cannot do is more useful than trying to assign a disease stage yourself.
Your practical checklist
- Bring earlier reports and your medication list.
- Identify your priority: pain control, fertility or diagnostic clarification.
- Ask when to return if the initial plan does not help.
Questions and answers
Should severe period pain be accepted as normal?
No. Pain that disrupts everyday life warrants care. Assessment also helps identify other conditions that produce similar symptoms.
Does everyone need surgery?
No. Investigation and treatment are individual. Surgery is one option, not an automatic first step for every patient.
