| Definition : It is a chronic condition in which the pancreas makes little or no insulin because the beta cells have been destroyed. About two-thirds of body cells require insulin to absorb glucose and in its absence, they will not be able to use the glucose (blood sugar) for energy. Type 1 diabetes usually comes on abruptly, although the damage to the beta cells may begin much earlier. Typical signs of Type 1 diabetes are a great thirst, hunger, a need to urinate often, and loss of weight. To treat the disease, the person must inject insulin, follow a diet plan, exercise daily, and test blood glucose several times a day. Type 1 diabetes usually occurs in children and adults who are under age 30. This type of diabetes used to be known as “insulin-dependent diabetes,” “juvenile diabetes,” “juvenile-onset diabetes” and “ketosis-prone diabetes. |
