THE DIABETES STORY.NORMAL PERSON The rise in blood glucose blood glucose Diabetology The principal sugar produced by the body from food–especially carbohydrates, but also from proteins and fats; glucose is the body's major source of energy, is transported to cells via the circulation and used by cells in the presence G after a meal stimulates the pancreas to secrete insulin I. Insulin attaches to the insulin receptors on the cell surface and enables glucose to enter muscle and fat cells, where it is stored of burned for energy. [ILLUSTRATION OMITTED] INSULIN RESISTANCE Insulin Resistance Definition Insulin resistance is not a disease as such but rather a state or condition in which a person's body tissues have a lowered level of response to insulin, a hormone secreted by the pancreas that helps to regulate the level The pancreas secretes sufficient insulin, but the body is resistant to the insulin. To compensate, the pancreas secretes more and more. The excess insulin manages to keep blood glucose levels within the normal range--though usually at the upper end of that range--so diabetes doesn't occur. However, the high insulin levels lead to high triglyceride levels, low HDL (Hardware Description Language) A language used to describe the functions of an electronic circuit for documentation, simulation or logic synthesis (or all three). Although many proprietary HDLs have been developed, Verilog and VHDL are the major standards. ("good") cholesterol, high blood pressure, and/or other signs of Syndrome X, which raise the risk of heart attack. [ILLUSTRATION OMITTED] TYPE 2 DIABETES type 2 diabetes n. See diabetes mellitus. The pancreas secretes sufficient insulin, but the body is resistant to the insulin. (In type 1 diabetes type 1 diabetes n. See diabetes mellitus. , the pancreas stops secreting insulin.) To compensate for insulin resistance, the body secretes more and more, but it can't keep up. Because glucose has trouble getting into the cells, blood glucose levels rise, and the person is diagnosed with diabetes. [ILLUSTRATION OMITTED] |
