Endometriosis is a long-term (chronic) condition where tissue similar to the lining of the womb is found elsewhere in the body. It’s very common, affecting around 1 in 10 women.

Symptoms of endometriosis:

• pain in the lower stomach, pelvis, lower back or legs
• painful periods which affect your day to day life – for example, you can’t go to school or work or take part in activities that you enjoy
• pain during ovulation
• heavy or long lasting periods
• pain during and after sex
• pain or bleeding when going to the toilet (pain before or after peeing or pooing)
• bleeding from your back passage (rectum)
• blood in your poo (usually at the same time as your period)
• bloating
• persistent exhaustion and tiredness
• difficulty getting pregnant

What causes endometriosis?

The exact cause of endometriosis is unknown. It’s sometimes believed to be genetic. That means if someone in your family has the condition, it’s more likely you may have it too.
