Bloating, abdominal pain and hiccups are related to indigestion, reflux esophagitis and gastric prolapse. Indigestion is caused by slow gastric motility and lack of digestive juice secretion. Many people with indigestion have a feeling of bloating in the stomach because food stays in the stomach for a long time, causing pressure on the stomach wall, and gas is released through the esophagus when food ferments and produces a lot of gas, thus causing hiccups. Reflux esophagitis is caused by the reflux of stomach acid into the esophagus and the violation of the esophageal mucosa. Since the esophagus passes through the fissure of the diaphragm, inflammation of the esophagus causes irritation of the diaphragm, resulting in spasm and contraction of the diaphragm and hiccups. Gastric prolapse, when severe, can lead to more severe prolapse when food is ingested, thus affecting the digestion of food by the stomach, which can also lead to abdominal distension and hiccups.
