Most diaper rashes have to do with impairment of skin integrity rather than any specific bacterial or fungal infection. Urine and stool acidity (the latter seen in diarrhea) and chronic wetness coupled with a warm barrier environment are all factors proposed as causes of diaper dermatitis (diaper rash). However, sometimes a superficial skin infection is a factor in diaper rash. The most common infectious cause of diaper rash is Candida albicans (yeast, a fungus).
What you wear can make a difference. Underwear with a cotton crotch, rather than one made from synthetic fabric, is recommended. Skirts and pants that are loose-fitting can help keep you cooler and drier. Avoid wearing tight pantyhose and any pants that are tight in the crotch. Change out of wet or damp clothes as soon as possible, including swimsuits and exercise clothing.
Garlic was shown in a lab study to be an effective Candida killer. But there is some debate over whether it will help cure yeast infections outside of a lab setting. If you’d like to try garlic to treat a yeast infection, add more garlic to your diet. Some websites recommend inserting garlic in the vagina, but burns and significant pain have been reported.
