ABSTRACT

Diabetes mellitus is one of the most common diseases in the Western industrialized countries with about 300 million affected patients worldwide. The hyperglycemic state of diabetes mellitus leads to changes in practically every cell type and organ of the human body. Skin changes are considered the most common manifestations of diabetes mellitus. As skin changes can manifest before onset of diabetes mellitus they may have a diagnostic relevance. Other changes and diseases of the skin develop during the course of diabetes mellitus and may be associated with complications in internal organs or may occur as an adverse effect of antidiabetic therapy. In particular the presence of the diabetic foot syndrome is associated with significantly increased morbidity and mortality of diabetes patients as well as with markedly elevated direct and indirect costs for the health care system. In this article the most common skin diseases of patients with diabetes mellitus as well as their pathophysiology and current treatment are reviewed.
