First of all, patients' eating habits will change greatly after the operation. If they eat too much or too fast, they may cause nausea and vomiting. Some patients need a long time to change their eating habits. Within two weeks after operation, the diet is mainly liquid, and two to four weeks are mainly soft meals, and then solid food can be added slowly.

Mild vomiting and flatulence are common. Eating half a sandwich and drinking half a glass of wine will make you feel full. You know, progress varies from person to person. Eat less and take your time. Please try to separate food and drink when eating. In addition, about 1/5 people may have gastric acid reflux after operation or need medical treatment. Six months after operation, you should receive long-term dietary guidance from a nutritionist to avoid malnutrition.
