Simplified trajectory of beta cell damage in type 2 diabetes. Obesity and the associated insulin resistance lead to beta cell overwork and the resulting hyperinsulinemia maintains blood glucose levels within the normal range. In case of genetic predisposition, metabolic stress, inflammation and other factors cause alterations in key beta cell organelles, which contributes to beta cell dysfunction and/or death. ER, endoplasmic reticulum.
