Yeast infection alternately referred to as Candidiasis, is a fungal infection due to any type of Candida (a type of yeast). It is a fungus that lives almost everywhere, including in your body. It is worth noting that a yeast infection is not always caused by Candida.   Yeast infections affect different parts of the body in different ways:

• White patches in your mouth
• This can spread to your esophagus, the tube that takes food from mouth to stomach especially in individuals who have a weakened immune system.
• Vaginal yeast infections that cause itchiness, pain and discharge
• Itching and rashes on the skin

If it affects the genital area, it is called a yeast infection. In women, it may be called a vulvovaginal yeast infection and in men, it’s called Balanitis.
