11 Signs and Symptoms of Prediabetes Worth Checking

1. Darkened Patches in Skin Folds

Velvety, darkened patches along your neck, armpits, or groin are known clinically as acanthosis nigricans. This physical marker develops when high circulating insulin stimulates localized epidermal cell growth.

Many people mistake these patches for sun damage or persistent dirt. In reality, they represent a classic dermatological indicator of advancing insulin resistance.

2. Increased Skin Tag Growth

Small, benign flesh growths frequently crop up along the neck, eyelids, and armpits. Excess circulating insulin accelerates cellular growth, encouraging skin tags to form in friction-prone areas.

Noticing a sudden increase in these outgrowths warrants a metabolic check. A routine blood panel can confirm whether shifts in glucose handling are responsible.
