Peptic ulcers are open sores that develop in the lining of your stomach, esophagus or the upper part of the small intestine (duodenum). An ulcer often causes burning pain that can worsen when your stomach is empty. Peptic ulcers can lead to internal bleeding (bleeding ulcer), infection or other digestive problems. Medication can manage your pain and encourage healing.
