Risk factors for oral thrush

Some risk factors can cause oral thrush to flourish. A weak immune system is at the topmost of this list. A weak immune system allows an imbalance of microorganisms in your body, and this can lead to an overgrowth of the fungus. Other risk factors include:

1. HIV

A study, conducted in the Journal of Pharmacy & BioAllied Sciences, presents a case of a male patient, 39, who suffered from oral thrush, and that helped the doctors determine that he had HIV.

There are white lesions on his tongue and palate, and it was seen that he suffered from erythematous candidiasis, a form of oral thrush. An HIV-induced erythematous candidiasis was finally diagnosed.

2. Chemotherapy or other cancer treatments

It all depends on the type of cancer and how intensive the treatment is, states a study, published by National Institutes of Health.

3. Diabetes

High sugar levels in the body make it conducive for the yeast to grow. According to this study, published in Current Medical Mycology, 55 per cent of diabetic participants were seen to carry candida in their oral cavity.
