Yeast is a fungus that normally lives in the v*gina in small numb
ers, according to WebMD. A v*ginal yeast infection means that too many yeast cells are growing in the v*gina.
These infections are very common.
Although they can bother you a lot, they are not usually serious. And treatment is simple.
What causes a v*ginal yeast infection?
Most yeast infections are caused by a type of yeast called Candida albicans. A healthy v*gina has many bacteria and a small number of yeast cells. The most common bacteria, Lactobacillus acidophilus, help keep other organisms-like the yeast-under control.
When something happens to change the balance of these organisms, yeast can grow too much and cause symptoms. Taking antibiotics sometimes causes this imbalance. The high estrogen levels caused by pregnancy or hormone therapy can also cause it.
