What causes a burning sensation in the stomach?

Stomach burning is caused by improper diet, indigestion, gastric ulcer, etc.

1.

Eating spicy food, excessive drinking, excessive caffeine intake, etc. may stimulate the gastric mucosa, causing increased acid secretion, resulting in acid reflux. Acid reflux will stimulate the esophageal mucosa, causing burning sensation.

2. Indigestion

causes food to stay in the stomach for too long, increasing the risk of acid reflux, causing stomach burning sensation.

3. Gastric ulcer

When there is gastric ulcer, acid is easy to erode the ulcer surface, causing burning sensation.
