There is no strict best time to drink brown sugar water for women who have had a cesarean section. It is generally recommended to start drinking brown sugar water about 3 days after delivery, but it should not be excessive. Cesarean section is the most common surgery in obstetrics, and lumbar and hard combined anesthesia, or lumbar anesthesia alone, is usually chosen. Since anesthesia drugs may cause nausea and vomiting in patients, water fasting is required 8 hours before the operation and 6 hours after the operation, with the purpose of avoiding asphyxiation caused by vomitus blocking the airway. During the process of water fasting, the maternal gastrointestinal motility is weaker due to the absence of food stimulation. In addition, anesthesia drugs will inhibit the function of the smooth muscle of the digestive system. Therefore, generally speaking, mothers need to eat a small amount of liquid diet after the postoperative anal exhaust, and most of the mothers can exhaust within 24 hours after delivery. Although anal exhaust suggests that the digestive function is recovering, but at this time you still can’t eat brown sugar water and other sugary foods, high-sugar foods will produce a large amount of glycogen in the digestive tract, which will combine with the intestinal flora, and easy to produce a large amount of gas, which will make the mothers suffer from abdominal distension symptoms. Generally 3 days after cesarean section, the mother has been able to get out of bed, exercise increased, gastrointestinal function is basically restored, urination is back to normal, at this time, you can drink a moderate amount of brown sugar water to replenish energy. Drinking brown sugar water after cesarean section should also be appropriate, should be a small amount, many times to drink, in addition to the concentration of brown sugar water is not easy to be too large, so as not to cause maternal blood sugar abnormalities, and even cause obesity and other problems.
