Type One, also known as Type 1 diabetes, is a chronic condition where the pancreas produces little to no insulin, a hormone essential for regulating blood sugar levels. This occurs when the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. People with Type One diabetes require lifelong management, including regular blood sugar monitoring and insulin therapy. The exact cause of Type One diabetes is not fully understood, but it is believed to involve genetic and environmental factors. Symptoms often include increased thirst, frequent urination, and fatigue. Early diagnosis and treatment are crucial to prevent complications and maintain a healthy lifestyle.
