2. What are Peptic Ulcers?

Peptic ulcers have two incarnations. A gastric ulcer is an open sore that develops on the inside of the stomach, while duodenal ulcers grow on the upper part of the intestines. Besides Zollinger-Ellison syndrome, gastrointestinal infections and long-term use of NSAIDs and aspirin can also promote peptic ulcer growth. Unless treated, the ulcers may cause internal bleeding as the sores enlarge or obstruct the digestive tract.
