If there is still residual pregnancy material in the uterine cavity after one month of medication abortion, it can be treated by purging. One month after medication abortion, if the residue in the uterine cavity can not be removed in time, it is not conducive to the repair of the uterus, and it is also easy to induce infection in the uterus, leading to the emergence of endometritis or uterine myositis. Patients will experience symptoms such as abdominal pain, abnormal vaginal discharge, and in severe cases, infertility may also occur, so the uterus should be cleared in a timely manner to promote the discharge of residual tissue. After the procedure, the patient should pay attention to rest, avoid overwork, eat more food rich in protein, vitamins, in order to facilitate the recovery of the body. If a woman has a drug abortion with residual tissue in the uterine cavity, it is recommended that she consult a doctor in a timely manner, under the guidance of the doctor, to complete the relevant examinations to determine whether or not it is necessary to take the removal of the uterus.
