The patient can choose according to the doctor’s advice and his own situation. 1. pain level: medical abortion is to contract the uterus through drugs to induce the discharge of embryonic tissue. The painless abortion procedure is to inject the patient with anesthesia and then clear the uterus, so the pain of drug abortion is greater than painless abortion; 2, damage to the uterine lining: if the patient is sensitive to drug abortion and can flow cleanly at one time, the damage to the uterine lining is smaller; as painless abortion is the use of instruments to scrape out the embryonic tissue, so the damage to the uterine lining is greater; 3, the possibility of infection: drug abortion and painless abortion have a lower chance of infection. The chance of infection is low for both medical abortion and painless abortion, but if the patient does not have a clean abortion, continues to bleed vaginally for a long time, or needs to have a clearing operation, the chance of infection may increase; 4. If patients decide to have a medical abortion, they need to go to the hospital for ultrasound examination after 1 week to determine whether there are residues in the uterine cavity. In addition, the patient should pay attention to personal hygiene, change underwear regularly and prohibit intercourse to prevent infection. Nutritious foods such as egg custard and shrimp congee can be consumed to promote recovery.
