In addition to medication, lifestyle changes such as correcting diet and lifestyle habits and controlling weight are also very important in the treatment of GERD. a. Because obesity increases abdominal pressure and can trigger or aggravate food reflux, weight loss should be actively pursued to improve reflux symptoms. Avoid wearing tight-fitting clothes and pants and minimize activities that increase intra-abdominal pressure to reduce reflux, such as excessive bending and squeezing of the abdomen. Third, reduce the amount of food, full stomach easy to appear lower esophageal sphincter transient relaxation. Eating should be chewed and swallowed slowly, pay attention to the small number of meals, especially dinner should not be too full. Avoid eating 2 hours before bedtime. Fourth, quit smoking and alcohol. Smoking can reduce the blood flow in the esophageal mucosa, inhibit the synthesis of prostaglandins, reduce the body’s resistance, making it difficult to recover from inflammation. The main component of alcohol is ethanol, which not only stimulates gastric acid secretion, but also relaxes the lower esophageal sphincter, which is one of the causes of gastroesophageal reflux and should be avoided as much as possible. V. Avoid the following foods and drinks: coffee, strong tea, acidic drinks, chocolate, cooking spices (such as chili, curry, pepper, garlic, mint), etc. Low-fat diet can reduce the frequency of reflux symptoms after eating. On the contrary, a high-fat diet can promote the release of cholecystokinin from the small intestinal mucosa, which can easily lead to reflux of gastrointestinal contents. Seven, the head of the bed is padded 15 to 500px (not pillows) when lying down, which is a good and effective way to reduce nighttime gastric reflux. Change the bad sleeping posture: some people like to sleep with both upper arms up or under the head, which can cause the diaphragm to be raised and the pressure in the stomach to increase, making gastric juice reflux up. Eight, increase protein intake, can stimulate gastrin secretion, so that the esophageal sphincter pressure increases. Therefore, protein can be appropriately increased in food, such as lean meat, milk, soy products, egg whites, etc. IX. Treat cough and constipation to reduce reflux induced by increased abdominal pressure.
