Learn about the different types of ulcers and the range of ulcer symptoms
When stomach acid and digestive juices eat their way through the lining of the digestive tract, sores called ulcers occur.
In general, the names of ulcers specify where they are found—so an ulcer located in the part of the small intestine called the duodenum is known as a duodenal ulcer, while a stomach ulcer is commonly referred to as a peptic ulcer. Also depending on where the ulcer is located, ulcer symptoms can vary widely. Some people may have no symptoms of an ulcer at all. Others can experience an intermittent burning and gnawing sensation along with feeling empty and hungry.
