3. Skin Problems
Sometimes most problems present on the inside of our bodies manifest on the surface of our body. Prediabetes is commonly known to cause scaly, velvety patches, and shiny or else dark patches on the skin, because of the increased level of insulin present in the blood.
Prediabetes can as well distort the blood circulation which will result to itching in extremities.
Full blown diabetic patients, have high risk of losing a foot due to severely compromised blood circulation, so you must act very fast if you suspect any skin issues.
