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 this condition need to manage their blood sugar levels through insulin therapy, diet, and regular monitoring. Symptoms of Type 1 diabetes can include increased thirst, frequent urination, extreme fatigue, and blurred vision. It is typically diagnosed in children, teenagers, or young adults, but it can occur at any age. Early diagnosis and treatment are crucial to prevent complications and maintain a healthy lifestyle.
