After the second day of abortion stomach distension is caused by the following reasons: first, the uterus is poorly restored, the uterine cavity has a silt blood stimulation caused by uterine contraction caused by stomach distension, the vaginal bleeding is often darker in color, you can take oral motherwort capsules for treatment to promote uterine contraction to discharge the silt blood. Secondly, the patient may have chronic pelvic inflammatory disease in the past, and the chronic abdominopelvic inflammatory disease caused by stimulation after the surgery will be aggravated, so it will lead to stomach distension. It is recommended that if the patient has a history of chronic pelvic inflammatory disease, the oral antibiotics should be appropriately prolonged after abortion, and the time to stop taking antibiotics should be decided according to the specific situation. If the bloating is still not improved after taking antibiotics for 3 consecutive days, it is recommended to go to the hospital for examination in time.
