Eating hiccups may be related to improper diet, or may be caused by reflux esophagitis, peptic ulcer and other diseases. 1. Improper diet: If there is improper diet, such as eating too much, too fast or drinking too much carbonated drinks and other bad eating habits, it is easy to cause hiccups, which is a normal physiological phenomenon. 2. Reflux esophagitis: Its causes mainly include delayed gastric emptying, increased esophageal sensitivity, decreased esophageal clearance, and decreased anti-reflux function. Common symptoms include acid reflux, heartburn, etc. Some patients may have hiccups when eating. 3. Peptic ulcer: the main cause of the disease is infection with Helicobacter pylori, followed by long-term application of non-steroidal anti-inflammatory drugs, etc., which can be triggered by smoking, alcoholism, tea and other factors, resulting in epigastric pain, belching, nausea, etc., which can be manifested as hiccups in some patients. In addition, eating hiccups may also be caused by chronic gastritis, indigestion and other diseases. If you exclude physiological factors, hiccups persist, you need to go to the hospital in a timely manner, under the guidance of a professional physician to clarify the specific causes.
