Heartburn after gastric cancer surgery is mainly due to the fact that whether proximal gastrectomy or distal gastrectomy is performed, the normal anatomical structure of cardia and pylorus is destroyed, and gastroesophageal reflux is manifested after surgery, and when gastroesophageal reflux is severe, the obvious symptom is heartburn. At this time there are some treatment, treatment methods: 1, if the heartburn is not particularly serious, through the control of diet, a small amount of food, after eating the patient do not immediately lie down, correct the position; 2, can eat proton pump inhibitor omeprazole, a variety of drugs to inhibit gastric acid, control the secretion of gastric acid; 3, can promote gastrointestinal motility, the application of drugs to promote gastric motility; 4, eat steamed buns, bread and other food, but also drink aluminum gel and other drugs that neutralize stomach acid. If the stomach acid is particularly serious, through the above conservative treatment, the control is not good, the final solution can be further to do a total gastrectomy, or do a reroute and then do surgery.
