Obesity and dermatology.
Obesity is associated with a number of dermatoses. It affects cutaneous sensation, temperature regulation, foot shape, and vasculature. Acanthosis nigricans is the most common dermatological manifestation of obesity. Skin tags are more commonly associated with diabetes than with obesity. Obesity increases the incidence of cutaneous infections that include: candidiasis, intertigo, candida folliculitis, furunculosis, erythrasma, tinea cruris, and folliculitis. Less common infections include cellulitis, necrotizing fasciitis, and gas gangrene. Leg ulcerations, lymphedema, plantar hyperkeratosis, and striae are more common with obesity. Hormonal abnormalities and genetic syndromes (Prader-Willi) are related to obesity and its dermatoses; however, cellulite is not related to obesity.
