Diabetes
Why glucose stays in the blood, and what separates type 1 from type 2.
Diabetes is not just «high sugar» by accident: it is insulin failing to move glucose into the cell, either because the pancreas stopped making it or because the body stopped responding to it.
We explain the difference between type 1 diabetes (autoimmune, no insulin) and type 2 (insulin resistance), what glycated haemoglobin actually measures, and why the damage builds up in small blood vessels before symptoms appear.
