Type I Diabetes is a chronic disease that affects millions of people worldwide. Also referred to as Insulin-Dependent Diabetes Mellitus (IDDM), this condition occurs when the body's immune system mistakenly attacks the cells in the pancreas that produce insulin. Type I diabetes can also be called juvenile diabetes, as it usually appears in childhood or adolescence. Other synonyms for this disease include early-onset diabetes, autoimmune diabetes, and insulin-dependent diabetes. Regardless of its name, this incurable disease requires daily insulin injections and lifelong management to ensure normal blood glucose levels, avoid complications, and maintain a healthy lifestyle.
