People with insulin resistance and prediabetes may develop acanthosis nigricans, characterized by darkened, velvety patches of skin, usually located on the back of the neck, armpits, groin, or other skin folds. These skin changes are often a visible indicator of underlying metabolic disorders.

Prediabetes can increase the risk of vision loss (retinopathy) because high blood sugar causes the lens of the eye to swell, impairing focusing ability. However, the blurriness disappears when blood sugar levels return to an optimal range.
