Old hiccups after drinking alcohol may be related to the drinking itself, or reflux esophagitis, chronic gastritis and other diseases. 1. Drinking alcohol: hiccups after drinking alcohol are mostly considered to be caused by a certain amount of carbon dioxide in the alcohol, and may also be caused by swallowing a large amount of gas when drinking too fast, which is a normal phenomenon. 2. Reflux esophagitis: the occurrence of this disease is related to factors such as delayed gastric emptying, abnormal esophageal sensation, weakened clearance ability and mucosal defense, decreased anti-reflux function, and obesity. Typical symptoms are heartburn, reflux, belching (hiccups), etc., so patients will appear after drinking old hiccups. 3. Chronic gastritis: the causes of the disease include Helicobacter pylori infection, autoimmune abnormalities, long-term alcohol consumption, smoking, improper use of non-steroidal anti-inflammatory drugs.
