Pancreatic cancer surgery is very traumatic, and patients take a long time to recover after surgery. When you see a patient successfully discharged from the hospital, it gives the health care workers a sense of accomplishment. What do I need to pay attention to in terms of diet? The pancreas is an important digestive and endocrine organ that regulates not only the breakdown of nutrients, but also the changes in blood sugar in the body. Therefore, these two aspects are affected to different degrees after pancreatic cancer surgery. Postoperative pancreatic cancer patients mainly eat to provide nutrition, but not only to ensure adequate and balanced nutrition, but also to take into account the damaged digestive function and to focus on an easily digestible diet. Generally speaking, the postoperative period is definitely fasting, and the postoperative requirements are supplied through intravenous rehydration. After 3 days or so, intestinal peristalsis is restored, and there is no abnormality in drinking water, then you can give oil-free liquid diet, such as rice soup, juice, etc. to stimulate the gastrointestinal tract, and then gradually give low-fat semi-liquid and low-fat general food. Pay attention to the things given are easy to digest, properly crushed, not easy to eat in large pieces. If necessary, you can give the elemental diet, increase the nutrition powder or nutrition liquid. Nowadays, enteral nutrition through nutrition tube is mostly used clinically instead of independent feeding after surgery. Pay attention to the direct injection of nutrition solution into the small intestine by drops, which is not easy to be too fast, otherwise it will easily cause abdominal distension, vomiting and other discomforts. When the patient is completely discharged from the hospital, he or she should mainly rely on the independent diet for nutritional regulation, which should still be based on easily digestible food and small and frequent meals. On the basis of ensuring adequate nutrition, the intake of lipids and proteins should be appropriately controlled, because excessive fat and protein intake will increase the burden on the pancreas and lead to indigestion and diarrhea. If the blood sugar is normal or stable in control, the intake of starchy food can be controlled without deliberately. If blood glucose is poorly controlled or fluctuates significantly, it should be regulated with medication under the coordination of an endocrinologist.
