What causes a heavy and bloated feeling in the abdomen during menstruation?

Patient's question:

No

Doctor's answer:

Young women experiencing lower abdominal pain during menstruation are mostly suffering from primary dysmenorrhea, which generally does not involve organic lesions. The condition often improves after a woman gets married or gives birth. If the lower abdominal pain during menstruation does not alleviate and even worsens after marriage, it suggests that it is not primary dysmenorrhea but rather caused by other factors. Some congenital uterine factors can also lead to lower abdominal pain during menstruation.
