Encyclopedia Article for ketosis

metabolic disorder marked by high levels of ketones in the tissues and body fluids, including blood and urine. With starvation or fasting, there is less sugar than normal in the blood and less glycogen (the storage form of sugar) in the cells of the body, especially the liver cells; fat accumulates in the liver, as do amino acids, from which the liver can produce more glycogen. Ketosis may be present in diabetes mellitus. In diabetic ketoacidosis, characterized by excessive levels of ketones in the blood that lead to a decrease in blood pH, very high blood sugar and severe intravascular and cellular dehydration create a life-threatening disorder that requires immediate treatment
