The causes of gastric hiccups are both physiological and pathological. Physiological causes include overeating, eating stimulating food, etc. Pathological causes include reflux esophagitis, gastritis, esophageal cancer and so on. The mechanism of gastric hiccups is the abnormal digestion and peristaltic function of the stomach, which is related to the digestive burden, food stimulation, diseases and other factors. 1. Physiological causes: such as overeating can lead to increased digestive burden; eating stimulating food can lead to stomach cramps. 2. Pathological causes: esophageal and gastric diseases can lead to decreased digestion and peristaltic function of the stomach. For example, reflux esophagitis can have symptoms such as acid reflux and heartburn; gastritis can have symptoms such as acid reflux and stomach pain; esophageal cancer can have symptoms such as progressive dysphagia and hoarseness. For gastric hiccups, it is recommended to actively consult a doctor to clarify the cause of the hiccups with the combination of symptoms and gastroscopy.
