Exploring Pathophysiology of Type I Diabetes

The video tutorial explains Diabetes Mellitus, focusing on Type 1 Diabetes. It covers the role of insulin, produced by the pancreas, in regulating blood glucose levels. The pancreas has both exocrine and endocrine functions, with the latter involving hormone production. Type 1 Diabetes is an autoimmune disease where the immune system destroys insulin-producing beta cells, leading to high blood sugar levels. The video also discusses the symptoms, such as fatigue and dehydration, and the diagnosis of Type 1 Diabetes, including the risk of diabetic ketoacidosis.
