Yeast infections are caused by an imbalance in the vaginal flora (the natural bacteria in the vagina), and things that can cause that imbalance are changes in diet, medications you may be taking that wipe out natural bacteria in the vagina (like antibiotics), or other illnesses like diabetes and autoimmune disorders that raise your risk for infection. The most common antibiotics that tend to lead to a yeast infection are those used to treat urinary tract infections, though McHugh said that's likely because doctors just prescribe those antibiotics to women more often.

The colloquial term "thrush" refers to the resemblance of the white flecks present in some forms of candidiasis (e.g. pseudomembranous candidiasis) with the breast of the bird of the same name.[67] The term candidosis is largely used in British English, and candidiasis in American English.[65] Candida is also pronounced differently; in American English, the stress is on the "i", whereas in British English the stress is on the first syllable.
Side effects of OTC medications for yeast infections are generally minor and include burning, itching, irritation of the skin and headache. However, as with any medication, more serious side effects are possible, though rare, and may include hives, shortness of breath and facial swelling. Seek emergency treatment immediately if any of these symptoms occur.
Yeast infections can occur in all age groups, from the very young to the very old. In babies, the most common ailments caused by yeast are diaper rash and a type of fungal infection in the mouth and throat called oral thrush. Rarely, a baby can develop a more serious yeast infection in the bloodstream or other organs. Symptoms depend on the type of infection and range from mild, local irritation to life-threatening illness in rare cases.
Essential oils should be mixed with carrier oils before use and never applied directly to the skin. People can mix 3-5 drops of oil of oregano essential oil in 1 ounce of sweet almond oil, warmed coconut oil, or olive oil. A tampon should be soaked in this mixture for a few minutes, then insert and change every 2-4 hours during the day. People should not leave a medicated tampon in for more than 6 hours. It is a good idea to test for allergies to oil of oregano on the forearm before use.
Infant yeast infection should be treated with a topical antifungal medicine such as nystatin four times a day. There are combination antifungal/steroid creams available, but the risk is that overusing steroid cream on sensitive private parts or the face can lead to a thinning out of the skin permanently, with what are called "atrophic changes." It's worth avoiding, and if you can get away with no steroid but just antifungal medicines for yeast infections, that is safer for Junior's bottom.
