As reported before about candidiasis, it was caused by candida. Candida yeasts are commonly present in humans, and their growth is normally limited by the human immune system and by other microorganisms, such as bacteria occupying the same locations in the human body.
Normal amounts of candida live in the mouth, stomach, and vagina, and do not cause infections. Candidiasis occurs when there is an overgrowth of candida. Causes may include taking certain drugs (especially antibiotics, corticosteroids, and some birth control pills), pregnancy, being overweight, having a bacterial infection, or several different health conditions (for example, a weakened immune system, diabetes, and psoriasis).
Actually, a weakened or undeveloped immune system or metabolic illness such as diabetes are significant predisposing factors of candidiasis.
