Yeast

Vaginal yeast infections are common, monilial overgrowths in the vagina and vulvar areas, characterized by itching,dryness, and a thick, cottage-cheese appearing vaginal discharge. The vulva may be reddened and irritated to the point of tenderness.

Yeast thrives in damp, hot environments and women in such circumstances are predisposed toward these infections.Women who take broad-spectrum antibiotics are also predisposed towards these infections because of loss of the normal vaginal bacterial flora.

Yeast organisms are normally present in most vaginas, but in small numbers. A yeast infection, then, is not merely the presence of yeast, but the concentration of yeast in such large numbers as to cause the typical symptoms of itching, burning and discharge. Likewise, a "cure" doesn't mean eradication of all yeast organisms from the vagina. Even if eradicated, they would soon be back because that is where they normally live. A cure means that the concentration of yeast has been restored to normal and symptoms have resolved.

The diagnosis is often made by history alone, and enhanced by the classical appearance of a dry, cheesy vaginal discharge. It can be confirmed by microscopic visualization of clusters of thread-like, branching Monilia organisms when the discharge is mixed with KOH.
