6 Precursors To Prediabetes You Should Be On The Lookout For

1. Darkened Skin

The Mayo Clinic says there aren’t always surefire signs of prediabetes, but one common symptom of Type 2 (adult onset) diabetes is a darkening of the skin in the areas around your neck and joint, in a condition called acanthosis nigricans.

This skin can also appear to be thicker than normal. If such a condition isn’t related to prediabetes, it could even be an indication of a cancerous tumor in one of your internal organs, so consulting a doctor is definitely the right choice either way.
