What causes stomach bloating at night?

Possible causes of nighttime stomach bloating include consuming excessive amounts of oily, spicy, or gas-producing foods during dinner, leading to increased intestinal gas; lack of physical activity after dinner, which slows gastrointestinal motility and causes indigestion; insufficient gastric motility, resulting in prolonged retention of food in the digestive tract; and gastrointestinal disorders such as chronic gastritis or gastric ulcers that disrupt normal digestive function. Additionally, inadequate warmth at night and exposure of the abdomen to cold temperatures may also trigger stomach bloating. Understanding these factors can help better prevent and relieve symptoms of nighttime stomach bloating. Patients experiencing such symptoms should seek timely medical treatment at a hospital.
