Vaginal Yeast Infection
Alternate Names : Vulvovaginal Candidiasis
A vaginal yeast infection is caused by one of a group of fungal organisms known as Candida. These include Candida albicans,
Candida tropicalis,
Candida glabrata, and Candida parapsilosis.
What is going on in the body?
Candida organisms are normally found in the vagina in small numbers. Their number is kept in check by the normal bacteria that also live there. Certain situations can disrupt this balance and allow a vaginal yeast infection to develop.
What are the causes and risks of the infection?
Vaginal yeast infections are caused by Candida organisms. Some diseases and conditions that increase a woman's risk for vaginal yeast infection include:
diabetes that is poorly controlled
HIV infection
immuodeficiency disorders, which weaken the woman's response to infection
menopause
pregnancy
Other factors that increase the risk for a vaginal yeast infection include:
a diet high in sugar
antibiotic therapy
corticosteroid use
oral contraceptive use
sexual activity, which can change the acid-base balance in the vagina
using feminine hygiene products
wearing tight clothing or nylon underwear
