Dysfunctional digestive tract dynamics after major gastrectomy requires dietary adjustments as well as medication as prescribed by the doctor. 1. Adjustment of diet: It is recommended to eat small meals and more semi-liquid food in order to reduce the burden on the stomach. At the same time, the diet needs to be kept light, avoiding cold, hot and hard foods, such as spicy hot, chilled watermelon and nuts, and spicy, stimulating and greasy foods, such as fried chicken, French fries and doughnuts. 2. Take medication: such as gastric tablets, domperidone and bifidobacteria capsules, etc. These medications can help promote gastric motility, aid digestion and relieve stomach discomfort. The above medications are recommended to be taken under the guidance of a specialist.
