How to judge whether belching or heating

There is a difference between hiccups and eructation. First, hiccups are mostly caused by spasm of the diaphragm. They are more common when eating too fast or too full or eating too cold or too hot food. They can occur continuously. In addition, diseases can also cause hiccups, such as brain tumors, mediastinal tumors, esophageal cancer, lung cancer, etc. Eructation refers to the gas produced in the stomach during gastritis passing through the esophagus to the throat and spilling out of the mouth. The sound is generally relatively long, and belching generally does not occur continuously. It is more common in gastritis, indigestion and other diseases.
