A stress ulcer is a chronic form of peptic ulcer. (True or False)

Stress ulcers are acute lesions that develop rapidly in response to severe physiologic stress such as trauma, burns, sepsis, or critical illness. They result from mucosal ischemia and increased acid exposure rather than chronic acid hypersecretion. Peptic ulcer disease, in contrast, is typically chronic and associated with Helicobacter pylori infection or long-term NSAID use.
