The digestive tract includes the stomach, esophagus and duodenum. Your duodenum is located in the upper portion of the small intestine where it joins the stomach. Ulcers can form in any part of the digestive tract, although they are most common in the duodenum. Foods that you consume are not responsible for forming an ulcer, but they can be responsible for delaying the healing process. Consuming a diet rich in low-fat, low-acid foods will decrease stomach acid production and help your ulcer heal.
