In a regular menstrual period, your uterine lining sheds and flows downward and out of your vagina.
But in Retrograde menstruation, the menstrual blood flows backward into the fallopian tubes and pelvis.
Although it’s a normal part of menstruation and doesn’t typically cause problems, knowing about its symptoms and causes can help in effective management.
Below, we have discussed some signs, causes, and treatments of Retrograde periods.
Retrograde Menstruation
Any person who menstruates can experience Retrograde periods, where the menstrual blood flows backward into the pelvic cavity
This blood has endometrial cells from the inner lining of the uterus. These cells may stick to the pelvic walls and surfaces of pelvic organs leading to Endometriosis.
Sampson’s theory of Retrograde menstruation suggested that there might be a possible relationship between this phenomenon and Endometriosis.
Healthcare providers also believe that people with Retrograde menses may risk developing Endometriosis.
In Endometriosis, the uterine tissue starts growing outside of the uterus.
When you have Retrograde menses, cells from your endometrium (the lining of your uterus) may grow on your abdominal or pelvic organs.
This growth of cells on the pelvic or abdominal organs leads to pain during menstruation.
