After an abortion procedure, there is bleeding. The bleeding is usually within a week, and most patients have cleared up 3-5 days after the procedure. If the bleeding does not clear up after the abortion, it is usually necessary to consider the possibility of infection, poor uterine contraction or intrauterine residue. It is recommended to rest, to have an ultrasound to understand the recovery of the uterus, and to treat with medications to promote uterine contraction and prevent infection. If it is determined that there are residues in the uterine cavity, promptly undergo an operation to remove the uterus. In addition, it is important to eat a light diet after surgery, not to stay up late, and to pay attention to the hygiene of the perineum to prevent the occurrence of reinfection. In a very small number of patients with persistent bleeding, it is necessary to exclude chorioamniotic disease.
