3. Skin Problems
Sometimes problems on the inside of our bodies manifest on the outside. Prediabetes is known to cause shiny, scaly patches or else dark, velvety patches on the skin, due to increased levels of insulin in the blood.
Prediabetes also begins to compromise blood circulation, which can cause itching in your extremities, especially the legs. Full blown diabetics are at risk of losing a foot due to severely compromised circulation, so you must act fast if you suspect your skin issues are related to prediabetes.
