by Kevin R. Sweeter (Author) Diabetes A disease in which the body's ability to produce or respond to the hormone insulin is impaired, resulting in abnormal metabolism of carbohydrates and elevated levels of glucose in the blood and urine. Diabetes is a disease that affects your body's ability to produce or use insulin. Insulin is a hormone. When your body turns the food you eat into energy, also called sugar or glucose, insulin is released to help transport this energy to the cells. Insulin acts as a key, where its chemical message tells the cell to open and receive glucose. If you produce little or no insulin, or are insulin resistant, too much sugar remains in your blood. Blood glucose levels are higher than normal for individuals with diabetes. Number of Pages: 74 Dimensions: 0.15 x 9 x 6 IN Publication Date: September 19, 2017
