Endometriosis: Why It Hurts, How It Is Diagnosed and What Helps
Endometriosis is a common cause of severe menstrual and pelvic pain that is mistaken for normal for years. Its symptoms, diagnosis, treatment and when to see a doctor.
Contents
Endometriosis is when tissue similar to the lining of the uterus grows outside its cavity and responds to the cycle's hormones, causing inflammation and pain. It affects about one in ten women of reproductive age and often hides for years behind the words "just painful periods". The key point to take away: severe pain that disrupts your life is not a normal thing to endure but a reason to be investigated.
What happens in the body
Normally the tissue lining the inside of the uterus (the endometrium) builds up and sheds with menstruation. In endometriosis, similar tissue ends up where it should not be: on the peritoneum, ovaries, uterine ligaments and sometimes further afield. It too responds to the cycle's hormones — swelling and "bleeding" — but has no way out. The result is chronic inflammation, pain and, over time, adhesions that "glue" the pelvic organs together.
It is this inflammation and these adhesions, not just "bleeding", that explain why the pain is often not confined to the menstrual days but becomes a constant background.
Symptoms not to write off as "just periods"
| Symptom | What it looks like |
|---|---|
| Severe menstrual pain | Disrupts daily life, not relieved by usual remedies |
| Chronic pelvic pain | Aches outside menstruation too |
| Pain during sex | Especially deep pain |
| Pain on bowel movement or urination | Worse during menstruation |
| Difficulty conceiving | Sometimes the first reason to seek help |
| Marked fatigue | Accompanies chronic pain |

How it is diagnosed
Diagnosis starts with a careful history of the pain and its relationship to the cycle — this alone gives a lot. Ultrasound and MRI show ovarian cysts (endometriomas) and deep lesions well, but small peritoneal lesions may not be visible.
Laparoscopy — surgery with inspection and biopsy — was once the only reliable way to confirm it. Current ESHRE guidance has shifted the emphasis: a diagnosis can be made clinically and treatment begun on symptoms, without delaying care until surgery. This is an important change — it cuts the years of waiting.
What helps
The goal of treatment is not to "remove endometriosis forever" (that does not happen) but to control pain and preserve quality of life and fertility. The main approaches:
- Pain relief — anti-inflammatory medicines as first line.
- Hormonal therapy — suppresses cyclic fluctuations and "calms" the lesions: combined methods taken continuously, progestins and, if needed, stronger drugs.
- Surgery — removing lesions and adhesions when medication is not enough or there are large endometriomas.
- Fertility — a separate task: from surgery to assisted reproductive technologies.
It is often team work: a gynaecologist, sometimes a pain specialist and a fertility doctor.

Endometriosis is a chronic but manageable condition. The most important decision is made early: not to endure pain that disrupts your life, but to have it investigated in good time. The specific approach is chosen by a doctor to fit your symptoms and goals.
FAQ
What is endometriosis?+
It is a condition in which tissue similar to the lining of the uterus grows outside the uterine cavity — on the peritoneum, ovaries and ligaments. It responds to the cycle's hormones, causing inflammation, pain and adhesions. Endometriosis is chronic and affects about 1 in 10 women of reproductive age.
How do I know severe period pain is not normal?+
Pain that interferes with study, work or everyday life, that ordinary painkillers do not relieve, or that makes you miss days, is not normal but a reason to be investigated. 'Put up with it, everyone has it' is harmful advice — it is exactly why endometriosis is diagnosed years late on average.
How is endometriosis diagnosed?+
It starts with a careful history of symptoms and an exam; ultrasound and MRI detect ovarian cysts and deep lesions. Laparoscopy with biopsy was once the 'gold standard', but current guidelines allow a clinical diagnosis and starting treatment based on symptoms, without waiting for surgery.
Can endometriosis be cured?+
It cannot be fully cured, but it can be managed. The goal is to control pain and preserve quality of life and fertility. Painkillers, hormonal therapy that suppresses cyclic fluctuations, and surgical removal of lesions when needed all help.
Does endometriosis affect pregnancy?+
It can reduce fertility, but many women with endometriosis do conceive. If conception does not happen, there are options — from surgery to assisted reproductive technologies. The approach is chosen individually with a doctor.
