Endometriosis is defined as, the presence of endometrial – like tissue outside the uterus/womb, which induces chronic and inflammatory reactions.

The lining of your womb/uterus is called the endometrium, every month a women’s body goes through hormonal changes. Hormones are released causing the lining of the womb to thicken in preparation for a fertilized egg, if pregnancy does not occur the lining (endometrium) is shed resulting in a period (menstruation) Endometriosis cells react in the same way except they are located outside the womb. Each month the cells grow, then break down and bleed, unlike a period there is no way for the blood to leave the body. This leads to inflammation, pain, and the formation of scar tissue (adhesions).

Endometriosis is most commonly found inside the pelvis, around the ovaries, the fallopian tubes, on the outside of the womb and ligaments (which holds the womb in place) or the area behind the rectum and womb called the pouch of Douglas. It can also be found on the bowel, bladder, the intestines, the vagina and the rectum. You can also have endometrial tissue growing in the muscle layer of the womb (this is another condition called adenomyosis). Endometriosis can grow in existing scars from previous operations such as caesarean section.

While some women experience painful symptoms and infertility, others have no symptoms at all.  Women of any age can be affected by endometriosis but it is rare for the condition to manifest before a girl has her first period.

It is estimated that one in 10 women have endometriosis and it takes an average of seven years for most women to be diagnosed. Endometriosis can often be confused with IBS (irritable bowel syndrome).

What do I do if I think I might have endometriosis?

Make an appointment with your GP if you have symptoms of endometriosis, especially if they're having a big impact on your life.

It may help to write down your symptoms before seeing a doctor.

Endometriosis UK has a pain and symptoms diary you can use.

What will happen at my consultation appointment?

We will request that you complete a pelvic pain questionnaire before your appointment.

During the consultation:

  • We will measure your body mass index (BMI) and take your weight and height measurements
  • the consultant will take a detailed medical history
  • you may be asked to have a vaginal examination.

The consultation will help you to make an informed decision about the personalised care you receive. You’ll be offered treatment based on your preferences, priorities and symptoms.


Please note that although some of these investigations may have been performed via your GP/consultant. These may need to be repeated.

How do I get referred for treatment?

There are two routes

  1. Your GP refers you into the hospital for assessment.
  2. Another consultant may refer you to our eam for an expert opinion and treatment.

When is a referral into hospital necessary?

Suspected Endometriosis can be treated in primary care by your GP. Referral to a Gynaecologist or a specialist centre should be considered if:

  • there is any suspicion or uncertainty over the cause of pain
  • if pain is severe and treatment fails in primary care
  • if severe/complex endometriosis is suspected e.g. endometrioma
  • if there are fertility issues link to Calderdale fertility services
  • if surgical and medical management is required.

Patients with Endometriosis will be referred to any of our general gynaecology consultants for treatment and management unless:

  • severe Endometriosis has already been diagnosed.
  • there is a higher likelihood of your Endometriosis being severe because you have 1 or 2 endometrioses.
  • you have recurrent Endometriosis.
  • you have significant pain or infertility problems.

  • oral hormonal treatments such as the combined oral contraceptive pill
