Acid reflux may be caused by improper diet, gastroesophageal reflux disease (GERD) or the presence of dry syndrome. It can be relieved by dietary adjustments and the use of medications such as omeprazole and mosapride. 1. Improper diet: If you eat spicy and stimulating food for a long time, it will stimulate the esophageal mucosa to reduce the barrier function of resistance to reflux, thus acid reflux occurs. At this time, patients should pay attention to adjust the diet, maintain a light diet, is conducive to reducing the symptoms of reflux, but also can use omeprazole, rabeprazole and other drugs to reduce the secretion of gastric acid. 2. Gastroesophageal Reflux Disease (GERD): Increased intra-abdominal pressure and abnormalities in the structure and function of the anti-reflux barrier can lead to GERD. At this time, patients should pay attention to diet control, moderate exercise, can also use mosapride, domperidone and other drugs to promote gastrointestinal dynamics, relieve symptoms. 3. Dry syndrome: it leads to abnormal peristalsis of the esophagus and reduced salivary secretion, which reduces the clearance of the esophagus to the reflux material and leads to the emergence of gastric acid reflux. At this time, prednisone and other drugs should be used to treat dry syndrome, after the primary disease is cured or improved, the symptoms of acid reflux can be improved. If acid reflux occurs, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, and then give targeted treatment or standardized treatment.
