The small intestine has an upper chamber that is called the duodenum. Its main purpose is to help to further break down the food that the stomach hasn’t completely digested yet before it makes its way into the lower portion of the intestinal tract. In order to do this, the chamber becomes filled with a liquid mixture that contains some special enzymes from the stomach, pancreas, gallbladder, and liver. Sometimes, if this liquid is too acidic, small holes form in the lining of the duodenum, which are called ulcers. Duodenal ulcers can cause a lot of pain and damage if they aren’t treated properly. So it helps to know what the symptoms of the ulcers are, what causes them to occur, and what the options are for treating them.
Information. Some people confuse duodenal ulcers with gastric ulcers. The difference between them is the location that they develop in. Duodenal ulcers only form in the duodenum. Gastric ulcers are located in the stomach. Doctors may refer to either type of ulcer as a peptic ulcer though.
