Introduction
Abortion can cause significant physical harm to women. Compared with medical abortion, surgical abortion results in less uterine bleeding and a shorter duration of postoperative bleeding; typically, bleeding ceases completely within 10 days after the procedure. In most cases, vaginal bleeding stops within a few days following surgical abortion, and rarely persists beyond two weeks. With minimally invasive painless abortion procedures, bleeding may even cease on the same evening as the procedure. Post-abortion bleeding should not exceed the volume of a typical menstrual period.

Miscarriage can cause significant physical harm to women. In addition to adequate rest and sufficient nutritional intake, women must closely monitor post-procedural bleeding. If bleeding persists for an unusually long duration or is excessively heavy following miscarriage, prompt medical evaluation and appropriate intervention are essential.

Typically, vaginal bleeding after surgical abortion lasts 7–14 days, with blood loss not exceeding the volume of a normal menstrual period. However, if bleeding exceeds typical menstrual flow, persists abnormally long, or is accompanied by abdominal pain, incomplete abortion must be considered. In such cases, immediate medical consultation is required to confirm diagnosis and initiate appropriate management. Compared with medical abortion, surgical abortion generally results in less blood loss and shorter duration of uterine bleeding; most patients experience cessation of bleeding within 10 days postoperatively.

Nevertheless, surgical abortion carries potential complications, including incomplete suction curettage, missed abortion, uterine perforation, cervical laceration, postoperative infection, intra- or postoperative hemorrhage, abortion syndrome, intrauterine or cervical adhesions, and menstrual irregularities. Typically, bleeding ceases within several days after surgical abortion, rarely extending beyond two weeks; with minimally invasive painless abortion, bleeding may even stop on the same day. Post-abortion bleeding should never exceed normal menstrual flow. Prolonged bleeding lasting more than one week after painless abortion may indicate inadequate rest.
