Diabetes is one of the most common chronic conditions, and every patient’s journey with it is unique — but the underlying mechanism comes down to insulin and glucose regulation. In this lesson, we’ll review how insulin deficiency or resistance leads to high blood sugar, the difference between Type 1 diabetes caused by immune attack on pancreatic beta cells and Type 2 diabetes driven by insulin resistance, and how treatment works by helping insulin “unlock” glucose channels. By the end, you’ll have a clear understanding of how diabetes develops and the critical role insulin plays in managing it.
