This point is made crystal clear even when we take a look back over the last few years. According to the National Sleep Foundation (NSF), a U.S. nonprofit organization of researchers, patients and health-care facilities, 20% of Americans reported getting six hours of sleep or less in 2009, compared to 13% in 2001.
An ulcer (/ËÊlsÉr/; from Latin ulcus, ulcer, sore) is a break in the skin or mucous membrane with loss of surface tissue and the disintegration and necrosis of epithelial tissue. A mucosal ulcer is an ulcer which specifically occurs on a mucous membrane.
A peptic ulcer is a nonmalignant, mucosal lesion of the stomach or duodenum in which acid and pepsin play major pathogenic roles. The major forms of peptic ulcer are duodenal ulcer (DU) and gastric ulcer (GU). For VAC purposes, entitlement for duodenal ulcer, gastric ulcer, or peptic ulcer includes entitlement for any benign ulcer of the stomach and/or duodenum.
