Dr Larisa Corda said: ‘Endometriosis is a very common condition amongst women that is essentially to do with finding tissue that belongs to the inside of the womb (the endometrium), elsewhere in the body, most typically the pelvis.’

Tissue similar to the lining of the womb can begin to grow in the pelvis, ovaries and fallopian tubes.

Dr Larisa continued: ‘It can lead to scarring and pain that is commonly experienced when a woman menstruates, although the pain can sometimes last throughout the entire cycle.’

These cells behave like normal womb cells, growing and breaking down during your monthly cycle, but unlike the cells in the womb, which are expelled during your period, the blood from endometrial cells is trapped inside the body with no where to escape.

This can lead to very painful and heavy periods, infertility, fatigue, bowel problems and infertility.
