Why does my stomach swell when it's hot and lighten when it's cold?

Disease analysis: Hello, abdominal distension is mostly caused by indigestion and slow gastrointestinal movement. People with gastritis and gastric ulcer often have bloating. Guidance: I suggest you eat less beans and high-fiber vegetables, eat more digestible porridge and soup, do more exercise, and eat some hawthorn and yeast to help digestion.
