Candidiasis of the skin is a very common infection. Candidiasis is often caused by the overgrowth of the fungus Candida albicans, which is a yeast. The fungus causes a red rash on the skin, which may be itchy or crusty. This fungus is the same fungus that can cause oral thrush and vaginal infections.
The infection can be on any part of the body, but it is usually found in warm and moist areas. The most common places are armpits, groin, under the breast, and between fingers and toes. If the infection is also in the nails, nails may look discolored or thicker than normal. Individuals may also experience another infection in the nail bed called paronychia, which makes the nail bed red, hot, and pus-filled.
Anyone can develop candidiasis of the skin, but it is more common in individuals who are overweight. People with diabetes may have a higher chance of getting the infection if their blood sugar is not well controlled. Taking antibiotics can increase your chances of getting candidiasis of the skin. Those with weakened immune systems may also experience widespread infection.
Doctors can make a diagnosis by examining the rash and possibly taking a small sample for testing. Good hygiene and keeping the affected skin dry and exposed to the air can help relieve the infection. There are also several over-the-counter ointments and medications that can treat the infection. Candidiasis of the skin can often reappear after it is treated. If you believe that you have candidiasis of the skin, it is best to consult your doctor about your treatment options.
