Journal Article
Kahal, H., Halama, A., Aburima, A., Bhagwat, A. M., Butler, A. E., Grauman, J., …Atkin, S. L. (2020). Effect of induced hypoglycemia on inflammation and oxidative stress in type 2 diabetes and control subjects. Scientific reports, 10(1), https://doi.org/10.1038/s41598-020-61531-z

Intensive diabetes control has been associated with increased mortality in type 2 diabetes (T2DM); this has been suggested to be due to increased hypoglycemia. We measured hypoglycemia-induced changes in endothelial parameters, oxidative stress marke...
