The Claim
Prolonged exposure to elevated plasma glucose concentrations selectively injures pancreatic beta cells and vascular endothelial cells, which mechanistically explains the impairment of insulin production and the development of vascular pathology leading to organ damage in diabetes.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When blood sugar stays too high for a long time, it specifically damages the cells that make insulin and the cells that line your blood vessels. This damage is exactly why diabetes stops your body from making enough insulin and causes serious blood vessel problems that harm your organs.
See the scientific wording
Pancreatic beta cells and vascular endothelial cells represent the primary tissue targets vulnerable to injury from prolonged exposure to elevated plasma glucose concentrations. This selective susceptibility underscores why diabetes specifically impairs insulin production capacity while simultaneously driving the vascular pathology responsible for organ damage in affected individuals.

High blood sugar over time specifically damages the insulin-making cells in the pancreas and the cells lining blood vessels, which explains why diabetes reduces insulin production and causes widespread organ damage.
