If the human body is to maintain normal functioning, it is essential for the body to provide an uninterrupted supply of energy from food. If there is a problem with the body’s digestive system, this energy supply will be interrupted, which can affect the normal functioning of the body and even affect the health of the body. Reflux of food into the esophagus is an abnormal physiological phenomenon, and when it occurs it is usually associated with reflux esophagitis. The prerequisite for reflux esophagitis is the reflux of gastric contents across the lower esophageal sphincter (LES) into the esophagus, and the inability of the esophagus itself to remove the reflux as quickly as possible, resulting in prolonged retention of gastric contents in the esophagus, and damage to the esophageal mucosa from the gastric contents, such as acid, bile acids, and pepsin, resulting in reflux esophagitis. If it is diagnosed as reflux esophagitis caused by food reflux, then while actively treating it, you also need to pay attention to do the following to avoid aggravation of symptoms for a normal diet. 1, quit smoking and alcohol, this is because tobacco contains nicotine, can reduce the lower esophageal sphincter pressure, so that it is in a relaxed state, aggravating reflux; wine is the main component of ethanol, not only can stimulate gastric acid secretion, but also can make the lower esophageal sphincter relaxation, is one of the causes of gastroesophageal reflux. 2, eat less and more meals, eat a low-fat diet, can reduce the frequency of reflux symptoms after eating. 3, dinner should not be too full, avoid lying down immediately after the meal. 4, pay attention to weight loss, because excessive obesity increased abdominal pressure, can promote reflux of gastric juice. 5, keep a relaxed mood and increase appropriate physical exercise. 6, try to reduce the activities that increase intra-abdominal pressure, such as excessive bending, wearing tight-fitting clothes and pants, tightening the belt. 7, in the process of sleeping, the head of the bed as a whole should be raised 10 to 15cm, to reduce the night reflux is a proven way.
