A 19-year old BCTC student was admitted to the UK Medical Center because of extreme fatigue and weight loss. For the previous year he had tired easily, had lost 64 pounds in the last 2 years, his present height is 71 inches and his weight 140 pounds. About 4 years previously, he began to urinate frequently at night, and since then had increasing thirst and high urine output. He came to the hospital because during the last 24 hours he was extremely thirsty and irritable, and drank about twelve 360 ml glasses of water. He was urinating hourly during the last 24 hour period and unable to get enough to drink. His gums were sore and he had recent difficulty eating because of the gum tenderness.
