Slow wound healing
Slow wound healing is one of the most troublesome symptoms of diabetes. It is not uncommon for a diabetic person to get a cut or bruise that just doesn’t heal. Extremities are more commonly involved in delayed healing due to long distances from the heart and poor circulation of the blood.
The reason behind this: High levels of sugar in the blood begin to damage and constrict blood vessels, which restricts circulation. A reduced flow of blood towards the damaged skin area results in delayed healing.
