Type 1 Diabetes: Causes, Symptoms, Complications

Type 1 diabetes

Type 1 diabetes is a chronic autoimmune condition where your body’s immune system mistakenly attacks the insulin-producing beta cells in your pancreas. This leads to a lack of insulin, a hormone that helps your body regulate blood sugar levels. Without enough insulin, sugar builds up in your bloodstream instead of entering your cells for energy, causing various symptoms and complications.

Here are some key facts about type 1 diabetes:
