What causes esophageal stricture?

Esophageal stricture may be related to esophageal inflammation, esophageal ulcer and esophageal tumor.

1. Esophageal inflammation

Long-term esophageal inflammation, such as reflux esophagitis and infectious esophagitis, can lead to esophageal mucosal damage and fibrosis, thus narrowing the esophageal lumen.

2. Esophageal

ulcer refers to the ulcer formed by esophageal mucosal damage, and severe ulcer may lead to local scar formation, resulting in esophageal stricture.

3. Esophageal tumor

When there is a tumor in the esophagus, with the tumor growing, it can form space-occupying lesions, and then lead to esophageal lumen stenosis.
