- Heartburn
- Regurgitation of food or liquids into the mouth
- Backflow of stomach acid into the esophagus (acid reflux)
- Difficulty swallowing
- Chest or abdominal pain
- Feeling full soon after you eat
- Shortness of breath
- Vomiting of blood or passing of black stools, which may indicate gastrointestinal bleeding
