It feels like fire in my stomach.

The stomach feels like fire, which may be caused by gastritis, reflux esophagitis, peptic ulcer and other diseases. The details are as follows:

1. Gastritis

causes acute or chronic inflammation of gastric mucosa due to stress, alcohol stimulation, trauma, Helicobacter pylori infection and other reasons. When the gastric mucosa is stimulated in an excited state, it will release a large amount of gastric acid. Excessive gastric acid secretion will cause symptoms such as stomach like fire and acid reflux.

2. Reflux esophagitis

due to decreased anti-reflux function, decreased esophageal clearance ability, weakened defense barrier of esophageal mucosa, abnormal esophageal sensation, delayed gastric emptying and other factors cause acid-base reflux leading to damage of esophageal mucosa, which will cause symptoms such as stomach like fire, acid reflux, belching, etc.

3. Peptic ulcer

Under the action of various pathogenic factors, inflammatory reaction and necrosis of gastrointestinal mucosa occur, resulting in ulcer formation, often manifested as upper abdominal pain, accompanied by acid reflux, belching, heartburn, nausea, vomiting and other symptoms.
