What Causes Constant Belching?
Belching—commonly referred to as “burping”—typically denotes the expulsion of gas from the stomach through the mouth. During meals, swallowing food too quickly and ingesting excessive air may easily trigger belching. However, belching can also occur even when one is not eating. Thus, experiencing one or two belches after a meal is considered a normal physiological response. Yet, if belching occurs frequently, it may indicate overeating or indigestion. Notably, belching may also arise without concurrent eating—especially following excessive food intake, inadequate rest after meals, or even nausea.

If persistent, intractable belching recurs repeatedly, a thorough medical evaluation at a hospital is warranted to rule out underlying pathological causes. Treatment may include herbal or pharmaceutical agents that strengthen spleen and stomach function. Should symptoms persist without improvement, further clinical assessment is essential.
Particularly, upper gastrointestinal evaluation—including gastroscopy and *Helicobacter pylori* testing—is recommended. Frequent belching is a common gastrointestinal symptom often associated with functional dyspepsia, chronic gastritis, or gastroesophageal reflux disease (GERD). In such cases, patients are advised to consume more fresh vegetables and fruits, chew food thoroughly and slowly, and consider prokinetic medications—for example, domperidone—to alleviate symptoms. When necessary, prompt medical consultation is strongly recommended.
