Elevated body iron stores, indicated by higher serum ferritin levels, are associated with a significantly increased risk of developing type 2 diabetes.
If you have high ferritin levels, it may indicate an increased risk for type 2 diabetes. This is likely due to oxidative stress damaging insulin-producing cells. You should discuss your ferritin levels with a doctor to determine if phlebotomy or dietary adjustments are appropriate, rather than self-prescribing iron restriction.
The meta-analysis and systematic review suggest that increased ferritin levels and heme-iron intake are both associated with higher risk of T2D.
Why this rating
Meta-analysis of 16 high-quality studies with consistent findings, though heterogeneity exists in cross-sectional data.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
