Endometriosis affects an estimated 176 million women worldwide – that’s one in 10 women on average.
Early diagnosis
The best way to start is by consulting with a specialist team. At HCA Healthcare UK, we have created this endometriosis awareness content hub to provide tips and helpful advice for women who might be struggling to reach a formal diagnosis or are not sure where to turn for treatment. For those women, we want to let you know that we have teams of specialists, across five different locations, who are here to listen to you and support you.

Top 3 questions about endometriosis
-
1. What are the symptoms of endometriosis? icon plus
The symptoms for endometriosis depend on where in the body the abnormal endometrial tissue is found, and therefore varies from person to person. The most common symptoms include:
- Painful or heavy periods
- Pain in the pelvic area
- Pain during sexual intercourse
- Irregular periods
- Infertility
Other symptoms may include tiredness, bleeding when opening bowels or pain when passing urine.

2. What conditions can endometriosis commonly be mistaken for? icon plus
Endometriosis is sometimes mistaken for other conditions that can cause pelvic pain, such as pelvic inflammatory disease (infection in the pelvis), adenomyosis (endometrial tissue that grows into the muscle layer of the uterus) ovarian cysts, irritable bowel syndrome (IBS), or interstitial cystitis (bladder pain). It’s crucial that you talk openly and honestly about your symptoms to your GP, and that you see a doctor who you feel truly listens to your concerns. -
3. How can you test for endometriosis? icon plus
Symptoms of endometriosis are similar to many other conditions, which means getting a diagnosis can take time as these other conditions will need to be excluded. If endometriosis is suspected, an ultrasound scan is often the first investigation, followed by a pelvic MRI if clinically indicated.
However, the only definitive way to make the diagnosis of endometriosis is by carrying out a laparoscopy – a procedure where a camera is inserted into the pelvis to help the surgeon identify and visualise any signs of endometriosis.

I cannot thank the team enough for what they have done for me - I will be forever grateful to them all. I woke up from surgery and felt like a completely different person. I felt lighter both physically and mentally, and now feel no pain at all. My skin is better, my weight is more manageable, and I am able to go to work and socialise without many of the worries I had before.”
