SWEAT RASH2 - WatsonsHealth


Sweat rash or medically known as candidal intertrigo or intertrigo, is the inflammation of the skin due to the infection of candida yeast and bacteria. It commonly appears on areas where sweat can be trapped and accumulated such as the underarm, on the back of the knees, under the breasts, in the groin area, between abdominal skin folds and in the spaces between the fingers and toes. Humidity, friction and lack of ventilation on these areas may cause the Candida to multiply.

This condition is more common on people who are:

  • Overweight
  • Have diabetes
  • Have HIV or are confined to bed for a long period of time
  • Have sweaty session at the gym

  • Red rash with scaling on the periphery
  • Stinging skin
  • Burning skin
  • Broken skin (in the space between fingers or toes)
  • Blisters
  • Foul-smelling odor
