The amount of time it takes for the discharge to clear up after a cesarean section varies from person to person, and is usually completed in about 3-4 weeks after the operation. In some cases, the uterus recovers slowly and it takes 1-2 months for the discharge to be complete. With the gradual peeling off of the meconium in the uterine cavity, the blood and necrotic meconium in the uterine cavity will be discharged through the cervix and vagina, which is known as bad dew. Depending on the color and nature of the discharge, it is classified as bloody, plasma, or white. Bloody discharge appears within 3 days after delivery and is bright red in color; plasma discharge is light red in color and lasts for about 10 days; and white discharge lasts for about 3 weeks. If the bloody discharge lasts for a long time after cesarean section, it is recommended to go to the obstetrics department of the hospital in time to check how the incision is healing. At the same time, you can use a few days of uterine contraction under the guidance of the doctor to promote uterine contraction, and be careful to avoid uterine infections.
