Acid reflux refers to the reflux of stomach contents through the esophagus to the oropharynx and the perceived appearance of acidic substances in the mouth. It is collectively referred to as reflux with the reflux of duodenal contents through the stomach and esophagus to the oropharynx and the perceived appearance of bitter substances in the mouth. The difference between acid reflux and vomiting is that the former does not have the accompanying symptoms of nausea and dry heaving. Physiological gastroesophageal reflux is seen in normal individuals and has no clinical significance. If reflux occurs more frequently than in normal people, failure to remove acidic digestive gastric juices as well as pepsin, bile, and pancreatic juices in a timely manner can cause inflammation, erosion, ulceration, and fibrosis of the esophageal mucosa, which is considered gastroesophageal reflux disease. What are the manifestations of GERD? Common symptoms are acid reflux, heartburn, regurgitation, belching and angina-like episodes of retrosternal pain. Atypical symptoms such as hoarseness, foreign body sensation in the throat, blocked feeling in the throat, chronic cough and asthma often lead to misdiagnosis. What factors are associated with the development of GERD? GERD is mainly caused by lowered lower esophageal sphincter (LES) pressure, transient LES relaxation, weakened ability of the esophagus to clear food, and irritation and damage to the esophageal mucosa by refluxed material (including stomach acid and bile). In addition to the above, many other factors are related to the patient’s age, smoking, alcohol consumption, obesity, psychological factors, dietary habits, exertion and certain medications. What medications are needed to treat GERD? It mainly includes acid suppressants, motivational drugs and mucosal protectors. What do I need to pay attention to when I have GERD? Learn to relax, avoid mental tension, and have regular living arrangements. 1, avoid alcohol and quit smoking. Because tobacco contains nicotine, can reduce the lower esophageal sphincter pressure, so that it is in a relaxed state, plus 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, pay attention to a small number of meals, eat a 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. 3, dinner should not be eaten too much, and avoid lying flat immediately after the meal. 4, obese people should reduce weight. Because excessive obesity increased abdominal pressure, can promote gastric reflux, especially lying position more serious, should actively reduce weight to improve reflux symptoms. 5, the head of the bed should be raised 10 cm to 15 cm overall when sleeping, to reduce the night reflux is a proven method. 6. Minimize activities that increase intra-abdominal pressure, such as excessive bending, wearing tight clothing and pants, and tightening the belt. If there is regular epigastric pain (when hungry or after a meal) or severe burning sensation, acute and severe abdominal pain should go to the hospital for medical attention. Another part of gastroesophageal reflux patients with hyperacidity There are five contraindications to the diet of people with hyperacidity: a. Frozen and overheated diet. Diet temperature moderate, drinking tea, soup should not be too hot. Second, eating excessive amounts of MSG, spicy and sour and overly salty food. The diet is mainly light, taste heavy will stimulate gastric acid secretion, a small amount of ginger and pepper, can warm the stomach and enhance the protective effect of the gastric mucosa. Third, eat too meat, too oily and fried food. The diet is based on easily digestible food, meat stir-fried and cooked, and vegetables should not be half raw. Fourth, there is no diet in moderation. It is advisable to eat less and more meals to avoid hunger pain, if the pain, you can eat a soda cookie or two. Five, drinking alcohol and coffee. Especially wine, too much stimulation of the stomach, will make the ulcer worse.
