Regurgitation four days after abortion is also a common phenomenon. After pregnancy, the hormone level changes in the body and stimulates the gastrointestinal tract, caused by the physiological reaction, but after the abortion of the female body hormone level will not immediately return to normal. Therefore, four days after the abortion regurgitation phenomenon is also normal. If there is no residue in the uterine cavity after the abortion, with the recovery of the body, the human chorionic gonadotropin in the body will gradually decline to normal, and most women will return to normal in about two weeks, and the discomfort caused by the change in hormone levels will also disappear. Therefore, within two weeks of the abortion, if the symptoms of regurgitation is normal, but two weeks later still regurgitation, it is abnormal, it is recommended to consult a doctor in time.
