It can be divided into organic and non-organic lesions according to the cause. It is recommended to consult a doctor to clarify the cause of belching and give reasonable dietary regimen with medication to generally improve the symptoms. I. Organic lesions: 1. Reflux esophagitis: During an attack of reflux esophagitis, gas in the duodenum, stomach, and esophagus will reflux with the contents, causing the patient to show hiccups. Clinically, the symptoms can be controlled by drugs such as ranitidine, domperidone and magnesium aluminum carbonate. For gastroesophageal reflux caused by esophageal hiatal hernia or other organic lesions, surgical treatment is also required; 2. Chronic gastritis: Patients with chronic gastritis will not be able to digest food in the stomach in time due to weakened digestive function, which will lead to the accumulation of fermentation in the stomach and the production of large amounts of gas, and when the gas pressure in the stomach is too high, it will lead to gas flowing backwards and upwards, the phenomenon of belching occurs. It is recommended that you should not drink strong liquor, strong tea, strong coffee in your daily diet, do not eat too acidic, too spicy, too hot, or pickled foods, and reduce the intake of salt. You should eat more easily digestible food, such as milk, fresh fruits and vegetables. Follow medical advice and take regular medications such as omeprazole, metoclopramide, domperidone and probiotics to reduce belching symptoms; 3. Peptic ulcers: Peptic ulcers can occur in locations such as the esophagus, stomach or duodenum, and ulcers in these areas can stimulate the movement of peripheral nerves, leading to muscle spasms around the esophagus and stomach, causing gas to come up and burp. Treatment is also divided into two areas: diet and medications, with the diet being consistent with the needs of patients with chronic gastritis. Medications are mainly H2 receptor antagonists and proton pump inhibitors. Second, non-organic lesions: 1. Functional dyspepsia: Patients are unable to digest food in a timely manner due to poor digestive function, and food hoarding in the stomach can cause the phenomenon of belching. There are no specific medications for this disease, and it is necessary to establish good habits, avoid smoking, alcohol and taking non-steroidal anti-inflammatory drugs. When mental stress is high, patients may also develop functional dyspepsia, which requires psychotherapy according to different characteristics of patients to eliminate their tension and anxiety. 2. Gas-swallowing disorder: Patients will unconsciously inhale large amounts of air, and when the gas pressure in the stomach is too high, the gas will flow backwards, resulting in frequent belching, often with hysterical overtones, and more pronounced in public episodes. In this case, the patient needs to seek a psychotherapist to relieve the adverse emotions of anxiety and tension through psychotherapy and to control the symptoms by means of acupuncture and oral sedative drugs. 3. Non-specific excessive belching: The patient has no symptoms of excessive swallowing and no other pathology, but only shows frequent belching for a long time, in which case it is called non-specific excessive belching, and often requires a visit to the local hospital to be treated by means of Chinese herbal medicine This condition is called non-specific excessive belching and often requires a visit to the local hospital for management by means of Chinese herbal medicine.
