Flatulence and hiccups can be caused by eating too fast, intestinal emptying obstacles, indigestion, chronic gastritis, reflux esophagitis and so on. 1. Eating too fast: eating too fast, easy to ingest too much air, causing involuntary contraction of the diaphragm, resulting in non-stop hiccups. 2. Obstruction of intestinal emptying: excessive gas and liquid accumulate in the intestines when the tension of the intestinal wall is weakened or when there is intestinal obstruction, causing symptoms such as bloating and hiccups. 3. Indigestion:The slowing down of gastrointestinal peristalsis frequency rhythm, weakening of gastrointestinal function, food retention in the gastrointestinal tract, or intake of unhygienic food leading to bacterial infections, is the gastrointestinal tract produces too much gas, which accumulates in the body and causes bloating and hiccups. Dietary impurity caused by bacterial infection, gastric dysfunction, excessive gas accumulation, resulting in abdominal distension and hiccups. 4. Chronic gastritis: most patients with chronic gastritis have no obvious symptoms, with indigestion, acid reflux hiccups, etc. as the main manifestations, which may be caused by a combination of gastric inflammation, gastrointestinal insufficiency of power, dysfunction of bacterial flora and so on. 5. Reflux esophagitis: the contents of the stomach or duodenum reflux into the esophagus, causing lesions of the esophageal mucosa, irritation of the esophagus resulting in hiccups, affecting the digestion of the symptoms caused by bloating. You can take acid-suppressing drugs such as omeprazole to inhibit the secretion of gastric acid; you can also take gastrointestinal stimulants such as domperidone to increase the pressure of the lower esophageal sphincter, improve esophageal peristalsis and promote gastric emptying. There are many causes of bloating and hiccups, it is recommended to consult a doctor in time, under the guidance of the doctor combined with the relevant examination to clarify the cause of the disease, to give targeted treatment, so as to avoid delaying the condition.
