Why statins might make you a little more likely to get diabetes
HMG-coenzyme A reductase inhibition, type 2 diabetes, and bodyweight: evidence from genetic analysis and randomised trials

Statins block a protein called HMGCR to lower bad cholesterol, but this same blockage also slightly raises your weight and blood sugar—even if you don’t eat more.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

HMG-CoA reductase inhibition with statins modestly increases the risk of developing type 2 diabetes, particularly in individuals with pre-existing insulin resistance.
People with a gene version that blocks HMGCR have slightly higher blood sugar and insulin levels — meaning their bodies are less efficient at managing sugar, even before they become diabetic.
Taking statins or having a specific gene version makes people gain a little bit of weight and get a slightly bigger waist, even if they don’t eat more — this is because blocking the HMGCR enzyme affects how the body stores fat.
Blocking the HMGCR enzyme — whether by statin drugs or your genes — makes you about 11–12% more likely to develop type 2 diabetes, and this isn’t because the drugs lower cholesterol.
Even though statins make you gain a little weight, that tiny gain can’t explain why you’re 11% more likely to get diabetes — something else about blocking HMGCR is making your body worse at handling sugar.
