Roughly one in ten women of reproductive age has endometriosis, and on average it takes seven to nine years from first symptoms to diagnosis. That delay happens because severe period pain is culturally normalised, and because the condition is invisible on the tests most women are given first.
Pain that stops you functioning is not normal, whatever you have been told.
What Endometriosis Is
Tissue similar to the lining of the uterus grows outside it, most often on the ovaries, the ligaments supporting the uterus, the pelvic lining, the bowel or the bladder.
This tissue responds to the same monthly hormonal signals as the uterine lining. It thickens and bleeds. But unlike menstrual blood, it has nowhere to escape to. The trapped blood causes inflammation, and over time inflammation causes scarring and adhesions that stick pelvic organs together.
That inflammatory and scarring process explains why the pain often extends beyond the period itself.
The Symptoms
Presentation varies widely, and severity of pain does not correlate well with how much disease is present.
- Period pain severe enough to require time off work or school
- Pelvic pain outside the period, sometimes constant
- Deep pain during or after intercourse
- Pain when opening the bowels or passing urine, particularly around the period
- Bowel symptoms that fluctuate with the cycle, often misdiagnosed as irritable bowel
- Heavy or irregular bleeding
- Profound fatigue
- Difficulty conceiving
The cyclical pattern is the clue. Bowel or bladder symptoms that reliably worsen around your period point toward endometriosis rather than a primary gut condition.
How Much Pain Is Too Much
A useful practical test: period pain that responds to simple painkillers and lets you carry on with your day is within the normal range. Pain that does not respond, or that stops you attending work, college or family commitments, is not.
Other markers that warrant assessment include pain that has worsened over the years, pain requiring stronger medication each cycle, or pain accompanied by vomiting or fainting.
If you have been told repeatedly that this is simply how periods are, seek another opinion. It is the most common reason for the diagnostic delay.
Why Diagnosis Takes So Long
A normal ultrasound does not exclude endometriosis, and this is the single biggest source of missed diagnoses.
Ultrasound reliably detects endometriomas, cysts of old blood on the ovaries, and can suggest deep infiltrating disease in experienced hands. It frequently misses superficial peritoneal disease entirely, which can still cause severe pain.
MRI adds detail for deep disease affecting bowel or bladder. The definitive diagnosis remains diagnostic laparoscopy, where a camera examines the pelvis directly and the lesions can be treated in the same procedure.
No blood test diagnoses endometriosis. CA 125 is neither sensitive nor specific enough and should not be used for this purpose.
Medical Treatment
Treatment aims to suppress the hormonal cycling that drives the tissue, and to control pain.
- Anti inflammatory painkillers: most effective when started a day before the period rather than once pain is established
- Combined hormonal contraception: often taken continuously to skip periods entirely
- Progestogens: tablets, injections, or a hormonal intrauterine system
- GnRH analogues: induce a temporary menopausal state, used for limited periods with add back therapy
Medical treatment controls symptoms but does not remove existing deposits, and symptoms typically return when it stops. It is not suitable while trying to conceive, which shapes the plan considerably.
Surgery and What It Achieves
Laparoscopic surgery removes or destroys endometriotic deposits, divides adhesions, and removes endometriomas. Done well, it improves pain substantially in most women and can improve fertility.
Excision of deposits generally gives more durable results than surface ablation, particularly for deep disease. Severe cases involving bowel or bladder need a surgeon experienced specifically in this, sometimes with colorectal input.
Ovarian surgery carries a consideration that matters for younger women: removing endometriomas can reduce ovarian reserve. If future fertility is important, that trade off should be discussed explicitly before surgery. Our endometriosis management service coordinates this decision with the fertility team.
Endometriosis and Fertility
Between a third and a half of women with endometriosis experience difficulty conceiving, through distorted anatomy, adhesions blocking tubes, inflammation affecting egg quality, and reduced ovarian reserve.
Many women with endometriosis conceive naturally. For those who do not, surgery may improve chances in milder disease, while IVF bypasses anatomical distortion and is often the more effective route in advanced disease.
If you have known endometriosis and want children, seek advice earlier rather than waiting the conventional twelve months, particularly if you are over thirty two.
Living With It Day to Day
Endometriosis is a long term condition and pain management extends beyond medication.
- Heat application, which genuinely helps and is underrated
- Pelvic floor physiotherapy, since chronic pain often creates secondary muscle spasm
- Regular gentle exercise, which reduces inflammatory pain over time
- Tracking symptoms against your cycle to identify patterns
- Addressing the mental health impact of years of chronic pain, which is substantial
Our physiotherapy department offers pelvic floor assessment, which many women with long standing endometriosis find makes a meaningful difference.
Endometriosis cannot yet be cured, but it can be controlled well, and the earlier it is recognised the less scarring accumulates. The most important step is refusing to accept disabling period pain as normal.
