Scott PY - 2020 T2 - McGraw Hill’s NAPLEX® Review Guide, 4e AB - Peptic ulcers are lesions in the stomach or duodenum that extend deeper into the gastrointestinal (GI) tract than other acid-related disorders. These lesions develop in response to damage by gastric acid and pepsin. Gastric ulcers occur primarily on the lesser curvature but may occur anywhere in the stomach. In contrast, duodenal ulcers occur in the first part of the duodenum. Peptic ulcer disease (PUD) is divided into three forms: (1) Helicobacter pylori (H. pylori)-induced; (2) nonsteroidal anti-inflammatory drug (NSAID)-induced; and (3) stress-related mucosal damage (SRMD). A comparison of characteristics of peptic ulcer is summarized in Table 43-1.
