The methods to inhibit gastric reflux after cardia resection include dietary modification and medication. 1. Diet regulation: after cardia resection, due to the loss of cardia’s function, gastroesophageal reflux is easy to occur after eating and drinking, so it is necessary to regulate the diet appropriately. Avoid consuming high sugar, stimulating, spicy, acidic, raw and cold food, and avoid eating before going to bed. In addition, you should move properly after eating to promote gastric emptying, which can relieve the symptoms of GERD. 2. Medications: After the surgery, the stomach is easily stimulated by the outside world, especially the excessive secretion of gastric acid or damage to the gastric mucous membrane. Medications that inhibit gastric acid and protect the gastric mucous membrane can be taken to improve the symptoms of reflux. Acid-suppressing drugs include cimetidine, ranitidine and so on. Gastric mucosa protection agents include aluminum thioglycollate, magnesium aluminum carbonate preparation and so on. The above drugs are prohibited for those who are allergic to them and should be taken in accordance with medical advice. If the patient’s symptoms of gastric reflux are serious, or continue to fail to improve, it is recommended to go to a regular hospital in a timely manner, after clarifying the cause of the disease, under the guidance of the doctor to carry out targeted treatment.
