What causes lower abdominal pain after miscarriage? Is it physiological or pathological?

Lower abdominal pain after miscarriage may be caused by physiological reasons. After miscarriage, the uterus will contract to promote the recovery of the uterus as soon as possible. When the uterus contracts, there will be lower abdominal pain. No special treatment is required. Lower abdominal pain after miscarriage may also be caused by pathological reasons, such as intrauterine infection, pelvic inflammatory disease, incomplete miscarriage, uterine perforation, etc.

When you do not want the child after an unexpected pregnancy and take measures to terminate the pregnancy, it is considered an artificial abortion; if the fetus is malformed or congenitally deficient after pregnancy, it may result in a natural abortion. Whether it is an artificial abortion or a natural abortion, it will cause certain harm to the female body. Some women often experience lower abdominal pain after abortion. So, what is the reason for lower abdominal pain after abortion?
1. Physiological reasons <br/>After pregnancy, the uterus will grow as the fetus grows. After termination of pregnancy, the uterus will return to its original size, and uterine contraction is usually used to promote the uterus to recover as soon as possible. Lower abdominal pain often occurs when the uterus contracts. This pain is usually rhythmic and regular, and does not last too long, so no special treatment is required.
2. Pathological causes
1. Uterine cavity infection <br/>If the operation is improper and the disinfection is not thorough during abortion, uterine cavity infection may occur; or if personal hygiene is not paid attention to after abortion, resulting in bacterial invasion and intrauterine infection, etc., it may cause lower abdominal pain. This pain lasts for a long time and is accompanied by increased lochia, fever, general weakness and other discomfort symptoms.
2. Pelvic inflammatory disease <br/>During the abortion process, if blood stasis flows into the pelvic cavity, it may block the pelvic cavity and induce pelvic inflammatory disease. Failure to pay attention to personal hygiene can cause bacteria to flow back, which can also induce pelvic inflammatory disease. At this time, there will also be symptoms of abdominal pain, accompanied by fever, chills, increased vaginal discharge, etc.
3. Incomplete abortion <br/>Whether it is a spontaneous abortion or an artificial abortion, there may be residual decidual tissue in the uterine cavity. In order to expel these remaining embryonic tissues from the body, the uterus will also have paroxysmal contractions, which will cause abdominal pain and vaginal bleeding. It can be confirmed by B-ultrasound examination, and another curettage is needed.
4. Uterine perforation <br/>If the doctor is inexperienced and the operation is improper during artificial abortion, uterine perforation may occur. This is a common postoperative complication of artificial abortion. At this time, there will often be severe pain in the lower abdomen, and heavy bleeding may cause shock.
