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 describes an open sore anywhere along the digestive tract, but most commonly in the upper portion of the small intestine. Although some ulcers result from stress and diet, more than half occur as a result of an infection with a bacteria known as H. pylori, according to the National Digestive Disease Information Clearinghouse.
