If the patient eats too much irritating food, such as pepper, onion, lemon, etc., it may stimulate the gastric mucosa and cause excessive gastric acid secretion, thus causing symptoms of stomach distension and heartburn.

2. Helicobacter pylori infection

If the patient has Helicobacter pylori infection, the pathogenic bacteria may cause damage to the gastric mucosa and stimulate excessive gastric acid secretion from parietal cells, causing stomach distension and heartburn.
