Endometriosis: When Period Pain Isn't “Just Pain”

There is a sentence I hear in my consulting room more often than any other: “I thought this was normal.” It is usually spoken by a woman in her late twenties or thirties, describing period pain that has shaped her life for a decade — pain that made her miss school, cancel plans, doubt herself, and apologise to employers. Somewhere along the way, she was taught that suffering was simply part of being a woman. It is not.

Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside it — on the ovaries, the pelvic lining, the bowel, and occasionally beyond. With every cycle, this tissue responds to hormones the way the uterine lining does: it thickens, breaks down and bleeds. But unlike a period, that blood has nowhere to go. The result is inflammation, scarring, and pain that can be severe and progressive.

How common is it — and why does diagnosis take so long?

Endometriosis affects roughly 10% of women and girls of reproductive age worldwide — about 190 million people. Yet the average delay between first symptoms and diagnosis is seven to ten years. Part of that delay is medical: symptoms overlap with other conditions, and definitive diagnosis has historically required laparoscopy. But a larger part is cultural. When girls are taught that periods are supposed to hurt, they do not report pain. When they do report it, it is too often minimised.

Pain that stops you living your life is never “just a period”. It is information, and it deserves investigation.

Symptoms worth taking seriously

• Period pain that does not respond to simple pain relief, or that keeps you home from work or school
• Pain during or after sex
• Pain with bowel movements or urination, especially during your period
• Heavy or prolonged menstrual bleeding
• Fatigue, bloating or nausea that tracks with your cycle
• Difficulty falling pregnant

No single symptom confirms endometriosis, and some women with extensive disease have little pain at all. But a pattern of cyclical, life-limiting symptoms is a signal to seek assessment — and to keep seeking it until you feel heard. A symptom diary tracking pain, bleeding and how symptoms affect your daily life is one of the most powerful tools you can bring into a consultation.

What treatment looks like today

There is no cure yet, but endometriosis is treatable, and treatment has become far more individualised. Options range from hormonal therapies that suppress the cycle, to excision surgery, to multidisciplinary pain management involving physiotherapy, nutrition and psychology. The right plan depends on your symptoms, your stage of life and your goals — including whether pregnancy is on your horizon. What matters most is that the plan is made with you, not for you.
