The treatment of GERD is a long and arduous process, and the disease is prone to recurrence, so how to prevent the recurrence of the disease? (1) Raise the head of the bed 10~15cm at night when sleeping to prevent acid reflux. (2) Do not eat too much, and eat less and more often. (3) Avoid strenuous exercise and forward leaning movements of the torso. (4) Eliminate factors that cause increased abdominal pressure, such as excessive obesity, severe cough, nausea, vomiting, severe erratic reflux (hiccups), asthma, constipation when holding the breath and straining to defecate, etc. (5) Avoid taking drugs that can reduce the tone of the gastroesophageal sphincter and promote reflux of gastric contents, such as theophylline, isoprenaline, dopamine, valium, and calcium channel blockers such as nifedipine and isoptin, etc. (6) Application for the power of drugs such as morpholine, Prebios (cisapride), etc., can make gastric peristalsis strengthen, gastric emptying accelerated, the prevention and treatment of the disease. (7) Antacid drugs can neutralize gastric acid and reduce the degree of damage to the esophageal mucosa by gastric acid, commonly used drugs include proton pump inhibitors such as Loxac, Oxy; H2 receptor inhibitors such as cimetidine, ranitidine, famotidine, etc.; gastric mucosal protective agents such as Gastrodex, Gefalte, magnesium oxide, aluminum hydroxide, aluminum thioglycollate, as well as Gastropin, Lodegastrin, Gastrin, etc. (8) Dilatation of esophageal strictures is performed to treat esophageal strictures and dysphagia caused by ulcer scarring. The method is to dilate the esophageal stricture and relieve the dysphagia by using techniques such as inflated balloon cannula. This method is especially suitable for elderly patients. (9) About 5-10% of patients with reflux esophagitis are ineffective in medical treatment and require surgical procedures to reconstruct the anti-reflux barrier of the esophagus and relieve esophageal obstruction.
