Causes
Esophageal stricture is typically caused by scar tissue that develops as a result of the following:
- Chronic heartburn , known as gastroesophageal reflux disease (GERD)—a condition where stomach acid flows into the esophagus, causing a burning sensation in the lower chest
- Prolonged use of a nasogastric tube (a tube that is inserted through the nose to the stomach)
- Ingestion of corrosive substances, such as household cleaning agents
- Treatment of esophageal varices (enlarged veins in the esophagus)
- Injuries caused by an endoscope (a thin, lighted tube used to see inside the body)
- Esophageal cancer
- Injuries caused by medications that can irritate the esophagus (such as some medications to treat osteoporosis and some antibiotics)
