Stomachless people are usually those after total gastrectomy. Diet after total gastrectomy should generally include small meals, light diet, and nutritional supplements. 1. Eat less and more meals: The main function of stomach is to store and partially digest food. Therefore, after total gastrectomy, the storage function will disappear. It is recommended to eat less and more frequent meals, otherwise, it will exceed the intestinal tolerance and cause indigestion. 2. Light diet: postoperative patients have weakened digestive ability, so light diet, eat more light vegetables, fruits and so on. 3. Supplementary nutrition: Post-operative patients need to supplement enough nutrition to restore their health, so the food mix should be balanced. Patients are suitable for slimy food, such as thick porridge with fish fillet. After total gastrectomy, try not to eat spicy and stimulating food, as well as high-fat fried and deep-fried food, and consult a doctor when discomfort occurs.
