What is Retrograde menstruation?

Retrograde menstruation is a condition in which menstrual blood flows backward into the fallopian tubes instead of exiting the body through the vagina. This can occur when the cervix is blocked or narrowed, preventing the menstrual blood from flowing out.

Retrograde menstruation can lead to pain, inflammation, and scarring of the fallopian tubes. It can also increase the risk of developing endometriosis, a condition in which endometrial tissue grows outside of the uterus.

Symptoms of retrograde menstruation can include:

* Pelvic pain, especially during menstruation

* Heavy menstrual bleeding

* Blood clots in the menstrual flow

* Nausea and vomiting

* Diarrhea

* Back pain

* Painful intercourse

Treatment for retrograde menstruation typically involves medication to reduce pain and inflammation and surgery to remove any scar tissue or blockages in the fallopian tubes.
