Gastric cancer has certain effects on the digestive tract, plus the stimulation of the digestive tract by radiotherapy, so the digestive tract function of gastric cancer patients is weaker. For such patients, dietary considerations are as follows: 1. In terms of nutrition, we should consider using finer and softer, low-fat and low-oil foods as supplements and avoid stimulation of stomach mucosa by too hot and too hard foods; 2. Ensuring sufficient energy supply is applicable to all cancer patients, especially the supplementation of high-quality protein, which is especially important in the late nutritional support of stomach cancer patients. For patients with gastric cancer, they should be given small doses of exercise, eat and move in balance, and eat in but also release out. Usually there are small walks or small sitting or meditation after meals, such exercises can accelerate metabolism and promote appetite improvement.
