Diabetes is the accumulation of glucose in the blood above the normal range. It can be caused by absence of insulin or insensitivity to the presence of insulin.

Diabetic foot ulcer (or simply diabetic foot) is a complication of diabetes, where excess accumulation of glucose in a lesion on the foot, promotes the growth of bacterial cells in the lesion, and if left untreated, can eventually left to amputation.

The patients response to buy over-the-counter-medicine to treat the calluses on my feet, means that he has understood that if the calluses (a thickened area of the skin as a result of excessive friction) are allowed, they can progress to being wounds that will encourage the growth of bacteria and eventually promote development of diabetic foot.
