Generally speaking, except for some special diseases that have dietary taboos before surgery, most surgeries have no impact on the patient's diet. Just pay attention to appropriate nutrition.
Principles of nutrition and diet that should be paid attention to before surgery:
General surgical operations will cause blood loss, and postoperative fever, infection, metabolic disorders, loss of appetite, decreased digestion and absorption function, Symptoms such as dry stool and even serious complications may occur. Due to blood loss and protein loss during surgery and increased catabolism after surgery, the body is prone to nutritional deficiencies. Therefore, improving the body's nutritional status and storing nutrients before surgery is an important link in the patient's recovery.
The ideal nutrition method before surgery is to provide a comprehensive and balanced nutritional supplement. The following nutritional and dietary principles must be paid attention to.
High-protein diet
Surgical patients must consume sufficient protein. If there is a lack of protein in the diet, it will cause dystrophic edema, which is detrimental to postoperative wound healing and disease recovery. A high-protein diet can correct excessive protein consumption caused by certain diseases, reduce postoperative complications, and help patients recover as quickly as possible.
A high-carbohydrate diet
A high-carbohydrate diet can provide sufficient heat energy, reduce protein consumption, prevent hypoglycemia, and protect liver cells from damage by anesthetics. In addition, it can also enhance the body's resistance and increase calories to make up for the energy consumption caused by insufficient eating after surgery.
Supplement adequate vitamins
Vitamin C can reduce capillary permeability, reduce bleeding, and promote tissue regeneration and wound healing. Vitamin K is mainly involved in the coagulation process and can reduce intraoperative and postoperative bleeding. Lack of B vitamins can cause metabolic disorders and affect wound healing and tolerance. Vitamin A can promote tissue regeneration and accelerate wound healing. Therefore, you must eat more fruits and vegetables rich in vitamins before surgery.
