Final answer:
Type 1 diabetes is a chronic autoimmune disorder characterized by the immune system attacking the insulin-secreting cells of the pancreas, resulting in a lack of insulin. Insulin injections are necessary for individuals with type 1 diabetes to manage their condition and maintain healthy blood sugar levels.
Step-by-step explanation:
Type 1 Diabetes
Type 1 diabetes is a chronic autoimmune disorder in which the immune system attacks the insulin-secreting beta cells of the pancreas. As a result, people with type 1 diabetes lack the insulin needed to keep blood glucose levels within the normal range. Type 1 diabetes may develop in people of any age but is most often diagnosed before adulthood. For type 1 diabetics, insulin injections are critical for survival.
Example:
A 14-year-old boy who is experiencing extreme fatigue, weight loss, excessive thirst, and frequent urination is most likely suffering from type 1 diabetes. In type 1 diabetes, the body's immune system mistakenly attacks and destroys the insulin-producing cells of the pancreas, leading to a lack of insulin and an inability to regulate blood glucose levels. Insulin injections are necessary for individuals with type 1 diabetes to manage their condition and maintain healthy blood sugar levels.
