Type 1 diabetes mellitus is a chronic autoimmune disease that affects the pancreas, an organ responsible for producing insulin. Insulin is a hormone that helps glucose, or sugar, enter the body’s cells for energy. In type 1 diabetes, the body’s immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas, leading to an absolute deficiency of insulin.
Without insulin, glucose cannot enter the cells, resulting in a buildup of sugar in the bloodstream. This condition can cause several severe complications, including diabetic ketoacidosis, a life-threatening condition that occurs when the body breaks down fat for energy instead of glucose, producing ketones as a byproduct.
Type 1 diabetes is usually diagnosed in children and young adults, although it can occur at any age. It is a lifelong condition that requires daily insulin therapy to manage blood sugar levels. Treatment also involves regular blood sugar monitoring, a healthy diet, and exercise.
While there is currently no cure for type 1 diabetes, advances in insulin therapy and blood glucose monitoring technology have significantly improved the quality of life for people with this condition. Ongoing research focuses on developing new treatments and ultimately finding a cure for type 1 diabetes.
