Lip Fungus

Last reviewed by Dr. Raj MD on January 12th, 2022.

Yeast is one of the organisms normally found in the mouth in small amount. The number of yeast in the mouth is controlled by the immune system.

However, overgrowth can happen in people with a weak immune system leading to all types of oral infection. Lip fungus is caused by Candida yeast, the very same organism found in the digestive and vaginal tract.

Candida or Monilia is the largest group of yeast-like fungi. In larger amount, it invades the body by creating toxins and stimulating hypersensitivity reaction. Lip fungus is common in babies and elderly. The infection is commonly known as thrush. (6, 7, 8)
