Today see's the launch of Endometriosis Awareness Week, but how many of you are aware of what it actually is.
More than two million women in the UK suffer from this painful condition, yet so many aren't aware of what it actually causes and the symptoms of it.
About 30 percent to 40 percent of women with endometriosis are infertile, making it one of the top three causes for female infertility.
It occurs when tissue like that which lines the inside of the uterus grows outside of the uterus, usually on the surfaces of organs in the pelvic and abdominal areas - places in which it is not supposed to grown.
It's a disease which affects women during their reproductive years and is the second most-common gynaecological disorder. Some women have no symptoms whist others may suffer from debilitating pain even with mild disease.
- Very painful cramps or periods
- Heavy perios
- Chronic pelvic pain (which includes lower back pain and pelvic pain)
- Intestinal pain
- Paind during or after sex
Whilst the disease can cause infertility in women, it can often be treated successfully using hormones and surgery.
