Risks of Iron Supplementation in Diabetes

Iron is a double- edged sword. Inoppleate use, especially ine the absence of true defeency or in the context of chronic matimation, can cause harm. The major risks in diabetic patients are outlined below.

Iron Overload and d Oxidative Stress

Excess iron promotes generation of reactive oxygen species via Fenton reaction, leading to lipid peroxidation, DNA damage, and protein modification.

If uncertain, a therapeutic trial of oral iron for 4- 6 weeks with reassessment of hemoglobobin and ferritin can clearfy. A rise in hemoglobobin ≥ 1 g / dL is diagnostic of IDA.
