The short explanation
Endometriosis is diagnosed from your symptoms, an examination and scans, and sometimes confirmed by laparoscopy (keyhole surgery to look inside). Scans can show some forms, such as cysts on the ovary, but a normal scan does not rule it out. It often takes years because severe period pain is dismissed as normal, symptoms vary widely, and early endometriosis cannot always be seen on imaging. Guidelines now say a clinician can suspect it and start treatment on symptoms alone, without waiting for surgery.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Symptoms that raise the question include period pain that stops you working or studying, pain during or after sex, pelvic pain between periods, painful bowel movements or passing urine during periods, and difficulty getting pregnant. It can affect women of any age from their teens.
- A symptom diary over two or three cycles makes a strong case at an appointment. If you have been told your pain is "normal" and it is stopping you living your life, it is reasonable to ask for a referral to a gynaecologist.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether you have endometriosis. It cannot replace an examination, a scan, or a specialist's judgement about whether surgery is needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Could my symptoms be endometriosis?
- What scan would you suggest, and what can and cannot it show?
- Can we try treatment now, without waiting for a laparoscopy?
- When would you refer me to a specialist?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
- Get emergency care now (call 112 or 108) for sudden severe pelvic pain with fainting, fever or vomiting, or severe pain if you could be pregnant.
- Book a routine appointment for period pain that painkillers do not control, or that makes you miss work, college or daily life.
