Heartburn and acid reflux are typical manifestations of diseases of the digestive system. They are caused by damage to the mucosa of the digestive tract for various reasons, and when digestive juices irritate the damaged mucosa, they cause local inflammation and symptoms of heartburn and acid reflux. Diseases that commonly cause heartburn and acid reflux include gastroesophageal reflux disease, peptic ulcer, and functional dyspepsia. Treatment is mainly given to symptomatic treatment and allopathic treatment: I. Symptomatic treatment: 1. Inhibition of gastric acid: For acid reflux, mainly acid-suppressing or acid-neutralizing drugs are used to control symptoms. Commonly used acid-suppressing drugs include omeprazole, rabeprazole, cimetidine, lansoprazole, etc. Neutralizing gastric acid drugs clinically used such as aluminum thioglycollate tablets, magnesium aluminum carbonate, aluminum hydroxide, magnesium oxide, etc.; 2, promote gastric power: heartburn feeling is usually induced by abnormal digestive function, can take to promote gastric power drugs, such as mosapride, domperidone, etc., can relieve the symptoms. Second, the cause of treatment: 1, gastroesophageal reflux disease: the main manifestations are heartburn, acid reflux, regurgitation and retrosternal pain. Clinical gastroscopy is the most accurate method to diagnose GERD. If symptomatic medication is ineffective or if esophageal strictures are present, dilatation or anti-reflux surgery may be performed. In addition, patients need to pay attention to their daily life, not to lie down immediately after eating, avoid eating two hours before bedtime, and elevate the head of the bed 15-20cm when sleeping to help relieve symptoms; 2. Peptic ulcer: mainly refers to chronic ulcers that occur in the stomach and duodenum. Patients will have symptoms of indigestion such as heartburn, acid reflux, belching, as well as abdominal distension and abdominal pain. For abdominal pain, anticholinergic drugs such as belladonna are available; for patients with H. pylori infection, H. pylori eradication medication is needed; 3, functional dyspepsia: also known as non-ulcer dyspepsia, is a chronic persistent, or recurrent epigastric syndrome, the main symptoms are heartburn, acid reflux, loss of appetite, nausea and vomiting. In addition to symptomatic treatment, digestive drugs such as dry yeast tablets, multi-enzyme tablets, etc. need to be given to help digestive function recovery.
