Causes of Yeast Infection
 
Yeasts are normally present in healthy human beings, their growth being restricted by the body’s immune system and competing microorganisms such as bacteria occupying the same areas. As a result, whenever the immune system weakens due of HIV/AIDS, steroids, cancer treatments, stress and inadequate nutrition can lead to yeast infection. Also, if the balance of microorganisms is disturbed due to various reasons like antibiotics, hormonal or physiological disturbances, which kill bacteria that compete for same resources as the yeasts can result in Candidiasis.
