Diet before hysterectomy should pay attention to eating easy-to-digest food, fasting for 8 hours before the operation and forbidding drinking for 2 hours before the operation. In order to prevent discomfort such as vomiting and bloating during or after surgery, which may lead to aspiration pneumonia or even asphyxiation, gastrointestinal preparation is routinely carried out 1 day before surgery, and it is also recommended to eat some easy-to-digest foods such as porridge and noodles on the day before surgery. 8 hours before the operation to fast, 2 hours to drink, but often the time of surgery is uncertain, for the first operation, it is generally recommended that the night before the operation after 12 o’clock no longer eat any food. However, the time of surgery is often uncertain, in order to avoid delays in surgery, for patients whose surgery is scheduled later, rehydration fluids are often given for symptomatic support, but if dizziness, cold sweats, and other discomforts occur during the fasting period, the medical staff should be notified immediately.
