Intertriginous Candida Treatment is really like most Candida treatments. According to the Merck Manuals http://www.merckmanuals.com/professional/dermatologic_disorders/fungal_skin_infections/candidiasis_mucocutaneous.html, the Intertriginous means areas such as the axillae, groin, beneath the breasts, and basically anywhere your skin folds. Most external Candida infections are Intertriginous because that is where Candida can grow easiest.
External Candida will flourish on your body much better if it meets certain requirements. THe most important is if you have a weakened immune system. Candida generally does not attack people with strong immune systems, so if you are weak, your chances are much higher. Hot weather and restrictive clothing can make you sweat, and will not allow your skin to breathe. That is a breeding ground for fungus.
If you want to treat an intertriginous candida infection, the most important thing to do is keep clean and dry. You have to have good hygiene and clean the area properly, using a good external antifungal. use baby powder (talc, NOT corn starch), to ensure that your areas are all properly dry. Make sure all your clothing is breathable, and loose fitting. If possible sleep naked, but always change your sheets daily.
After ensuring that you are always dry, make sure to change your diet to good foods that will fight off the Candida. If you have done all of these things, you should see good improvement.
