Heartburn
Another common symptom of duodenal ulcer is heartburn. This digestive issue occurs when acid in the stomach flows up into the esophagus, which is responsible for carrying food to the stomach from the mouth. It results in a burning sensation in the upper belly or below the breastbone. Sometimes, you might feel an acrid and foul taste in your mouth. Since heartburn is not an uncommon problem, it can be hard to diagnose duodenal ulcers with this symptom. If you experience heartburn quite often, then make sure to visit your healthcare provider. In some cases, a visit to a gastroenterologist is needed to find out the underlying cause. [3]
