The high incidence of reflux esophagitis is closely related to obesity, excessive psychological stress, smoking, and improper alcohol consumption. Treatment and prevention need to do: (a) the diet should eat easy to digest, soft food, need to reduce the amount of food, chew and swallow slowly, preferably a small number of meals, less stimulating food. (B) dinner is not full, avoid lying down immediately after the meal, do not add meals four hours before bedtime to prevent aggravation of symptoms. (C) less acidic, sweet, stimulating drinks and food; less or no food that can cause lower esophageal sphincter tension, such as strong tea, coffee, cocoa, chocolate, fresh lemon juice, fresh orange juice, tomato juice and other acidic drinks and stimulating spices, such as curry, pepper, mint, chili, etc. (D) avoid alcohol and quit smoking: as tobacco nicotine can reduce the lower esophageal sphincter pressure, leaving it in a relaxed state, plus reflux; wine, the main component of ethanol, not only to stimulate gastric acid secretion, but also to relax the lower esophageal sphincter, is one of the causes of gastroesophageal reflux. (E) reduce fat intake, fat can stimulate the secretion of cholecystokinin to cause lower esophageal sphincter tension, prompting gastroesophageal reflux, while reversing the pressure difference between the stomach and duodenum, causing the duodenal contents to flow back into the stomach, as into too much fat can delay the emptying of the stomach, increasing epigastric discomfort, making the stomach swell. Therefore, attention should be paid to the diet with less fat, cream and cooking oil, should be boiled, stewed, blanching, braised, steamed, eat less and do not eat fried food. (F) increase protein intake to stimulate gastrin secretion, so that the esophageal sphincter pressure increases, so the food can be appropriate to increase some protein, such as lean meat, milk, soy products, eggs, etc.. (vii) Obese people should reduce their body weight. Because excessive obesity increased abdominal pressure, can promote gastric reflux, especially lying position more serious, should actively reduce weight to improve reflux symptoms. (H) to maintain a relaxed mood, increase the appropriate physical exercise. (ix) The overall head of the bed should be raised 10 cm-15 cm at bedtime, which is a proven way to reduce nighttime reflux. (J) Minimize activities that increase intra-abdominal pressure, such as excessive bending, wearing tight-fitting clothes and pants, and tightening the belt. (xi) Medication should be administered under the guidance of a physician to avoid the side effects of indiscriminate drug use. The common drugs that cause drug esophagitis are antibiotics (such as tetracycline, doxycycline), anticholinergics, iron preparations, potassium chloride extended-release tablets, quinidine, aspirin, and non-steroidal anti-inflammatory drugs. The esophagus and stomach can be healthy for you if you pay attention to the diet and correct bad habits in your life. They need your attention and careful care.
