(HealthDay News) -- Barrett's esophagus may occur as a complication of gastroesphageal reflux disease (indigestion). When stomach acid backs up into the esophagus, it can cause changes in the esophageal lining, triggering Barrett's esophagus. In some cases, it can lead to cancer.
The American Academy of Family Physicians says these warning signs could indicate Barrett's esophagus:
- Having three or more instances of heartburn per week.
- Having heartburn over a number of years.
- Difficulty or painful swallowing.
- Losing weight without trying.
- Bloody or very dark stools.
- Unexplained vomiting.
