What causes stomach bloating and belching?

Under normal circumstances, stomach bloating and belching may be caused by dietary factors, gastrointestinal dysfunction, gastritis, cholecystitis, intestinal obstruction, and other reasons. Management should be based on the specific situation.

1. Dietary factors: Consuming excessive gas-producing foods such as legumes and carbonated beverages, overeating, or eating too quickly may lead to stomach bloating and belching. It is recommended to adjust eating habits, reduce intake of gas-producing foods, chew food thoroughly, and avoid overeating.

2. Gastrointestinal dysfunction: Long-term mental stress and irregular lifestyle may cause dysfunction of the gastrointestinal nervous system, leading to disordered gastrointestinal motility. When gastrointestinal motility slows, food remains in the stomach for too long, ferments, and produces gas, causing bloating and belching. It is recommended to adjust lifestyle and emotional state, maintain a regular schedule, and reduce stress through exercise, listening to music, and other methods.

3. Gastritis: Gastritis can damage the gastric mucosa, impair normal digestion, delay gastric emptying, cause food to accumulate in the stomach, produce gas, and lead to bloating and belching. It is recommended to take medications such as omeprazole enteric-coated capsules, cimetidine tablets, and domperidone tablets under a doctor's guidance.

4. Cholecystitis: Cholecystitis can affect the normal secretion and excretion of bile, potentially leading to incomplete fat digestion and impaired digestion and absorption in the gastrointestinal tract, resulting in symptoms such as stomach bloating and belching. It is recommended to take medications such as diclofenac sodium enteric-coated tablets, pethidine hydrochloride tablets, and ursodeoxycholic acid tablets under a doctor's guidance.

5. Intestinal obstruction: In intestinal obstruction, intestinal contents cannot pass normally, causing gas and fluid to accumulate in the intestine, leading to intestinal distension. Gas in the stomach also cannot be expelled smoothly, causing bloating and belching. It is recommended to take medications such as pantoprazole sodium enteric-coated capsules, cisapride capsules, and glycerin suppositories under a doctor's guidance.

If symptoms of stomach bloating and belching persist without improvement, timely medical consultation and comprehensive examinations are recommended to determine the exact cause. Self-medication should be avoided to prevent delays in treatment.
