Burping generally refers to belching, but burping is sometimes caused by eructation. Belching refers to the gas that travels up from the inner tract of the stomach until it reaches the pharynx and eventually spills out of the mouth, mostly after a meal, not frequently, and usually without significant discomfort. Belching may be caused by poor gas containment in the stomach, such as swallowing too much gas, eating too fast, eating too much, etc., most do not need special treatment. Upset is mostly caused by spasm of the diaphragm, with frequent sharp and loud noises coming from the throat, which are often uncontrollable, mostly due to eating too fast, being too full, or ingesting food that is too cold or too hot. Most hiccups resolve on their own within a short period of time; a few will persist for a long time, and antispasmodic medications, such as atropine and scopolamine, can be used under the supervision of a physician if necessary. Hiccups are mostly transient and do not need to be treated. If they occur for a long time and repeatedly, it is recommended to consult a doctor in time to avoid delays.
