Lower LDL-cholesterol levels causally protect against type-2 diabetes, which may explain the increased T2D risk observed with statin therapy.

If you are taking statins for cholesterol, be aware that they may slightly increase your risk of type-2 diabetes. Regular monitoring of blood sugar levels is advisable. Do not stop medication without consulting your doctor, as the cardiovascular benefits often outweigh this risk.
