Type 1 diabetes is a chronic condition where the body cannot produce insulin, a hormone that helps regulate blood sugar levels. This occurs because the immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. People with type 1 diabetes need to manage their blood sugar through insulin therapy, diet, and regular monitoring. Symptoms of type 1 diabetes can include increased thirst, frequent urination, extreme fatigue, and blurred vision. While it typically develops in children and young adults, it can occur at any age. Early diagnosis and treatment are crucial to prevent complications and maintain a healthy lifestyle.
