The symptoms of abdominal pain after abortion are mainly considered to be related to uterine contraction, improper surgical operation and postoperative infection. 1. Uterine contraction: after abortion, the uterus will have normal contraction. Since abortion is an invasive operation, symptoms such as abdominal pain may occur during the contraction of the uterus. This is a normal physiological phenomenon and there is no need to worry. 2. Improper surgical operation: If the uterus is severely damaged or there is residual embryonic tissue in the uterus, it may also trigger paroxysmal contractions and symptoms of abdominal pain. 3. Post-operative infection: If you don’t do a good job of hygiene after an abortion, leading to reproductive infections, such as cervicitis and other diseases, may also trigger abdominal pain. If the symptoms of abdominal pain are more serious, it is recommended to seek medical treatment as soon as possible.
