High blood glucose levels can also predispose people with diabetes to developing common fungal skin infections from organisms such as Tinea and Candida.
Fungal infections can occur just about anywhere, including the feet (Tinea pedis), the hands (Tinea manuum), the body (Tinea corporis), and the groin (Tinea cruris).
Tinea pedis, or athlete’s foot, usually occurs in the web spaces between the toes or on the soles of the feet.
Lesions are itchy and may develop vesicles (sacs filled with air or fluid) or may simply be red and scaly.
It is usually contracted by walking barefoot on a contaminated floor. To help prevent athlete’s foot, it is always a good idea to wear slippers or shoes of some sort in public areas such as locker rooms.
Tinea manuum is characterized by papules (small, raised pimples or swellings), vesicles, or scaling, typically on the dominant hand, and is associated with touching athlete’s foot lesions.
Tinea corporis, or ringworm, presents as multiple red or pinkish circular lesions with a distinct, scaly border. In severe cases, the lesions may merge, forming large, discolored areas on the body.
Tinea cruris, or jock itch, results in red to brownish, scaly, itchy lesions that cover the groin and sometimes extend to the pubic region and upper thighs.
Candidiasis of the skin tends to occur in folds of skin such as the underarms, groin, under the breasts, and between the buttocks.
This condition begins with pustules on a red base that eventually result in softened, thickened areas of skin.
All of these superficial fungal infections are treated in more or less the same way.
Applying antifungal creams two to three times daily for approximately two to four weeks should clear the infection.
Keeping the affected areas dry, and using medicated powders in skin folds to reduce friction and moisture are also helpful measures.
Infections that don’t respond to topical treatment may be treated with oral antifungal medicines.
