It is not normal to have bloody discharge after cesarean section. It is mainly due to slow recovery of uterus and late discharge of malignant dew. If the bleeding is serious, you should go to the hospital to clarify the specific cause of treatment. 1, slow recovery of the uterus: the slow recovery of the uterus leads to the lack of drainage of malodorous fluid, you need to pay attention to rest and reasonable nutrition. You can eat more meat, such as lean pork, chicken, fish, etc. You can also drink soups, such as chicken soup, pig trotters soup, cinnamon soup, jujube soup, etc., to replenish the blood and promote the early discharge of the dew. 2. Poor uterine regeneration: poor uterine regeneration is mainly considered to be caused by decreased contraction of the uterus, postpartum placenta or fetal membrane residue, uterine or pelvic infections. Generally, there will be a large amount of bloody malodorous fluid, and if it is accompanied by infection, it will also cause fishy smell, sometimes accompanied by abdominal cramping and fever and other symptoms. The main treatment is to promote contraction of the uterus. You can use uterine contraction agents, such as uterine contractin, ergometrine, misoprostol, etc. You can also take Chinese medicine such as motherwort granules to promote contraction of the uterus. If there is infection, antibiotics should be applied to fight infection, but they should be used under the guidance of a doctor. And for the presence of placenta-fetal membrane residue of the mother, if necessary, can be cleaned up surgery; 3, uterine incision diverticulum: after surgery due to poor healing of the incision resulting in diverticulum at the incision, causing a significant prolongation of the menstrual period, you can perform hysteroscopic repair surgery for treatment. If the diverticulum is large, the incision can only be re-stitched and repaired by opening the abdomen again. The damage of caesarean section to the mother is relatively large, after the operation should pay attention to diet, eat more fresh vegetables and fruits, avoid excessive strain, keep personal cleanliness and hygiene, avoid sexual life until the dew is clean.
