Oral thrush, also known as oral candidiasis, is a common fungal infection that affects the mouth and throat. It is caused by the overgrowth of a type of yeast called Candida albicans. While this yeast is present in the body in small amounts, it can grow rapidly and cause an infection under certain circumstances.
Here are some of the common causes of oral thrush:
Weakened immune system: People with weakened immune systems are at a higher risk of developing oral thrush. This includes individuals with HIV/AIDS, those undergoing chemotherapy or radiation therapy, and those taking immunosuppressive drugs.
Medications: Certain medications, such as antibiotics and corticosteroids, can disrupt the balance of microorganisms in the body, leading to an overgrowth of Candida.
Diabetes: High blood sugar levels in people with diabetes can create an environment in which Candida can thrive.
Dry mouth: A dry mouth can create an environment in which Candida can grow. This can be caused by medications, certain medical conditions, or simply not drinking enough water.
Smoking: Smoking can irritate the mouth and throat, making it easier for Candida to grow.
Poor oral hygiene: Poor oral hygiene, including not brushing and flossing regularly or not cleaning dentures properly, can create an environment in which Candida can grow.
Symptoms of oral thrush include white or yellowish patches on the tongue, inside of the cheeks, or roof of the mouth, soreness or burning in the mouth, and difficulty swallowing. Treatment for oral thrush typically involves antifungal medications, such as nystatin or fluconazole, as well as addressing any underlying causes, such as adjusting medications or managing blood sugar levels in people with diabetes. It is also important to maintain good oral hygiene practices and to avoid smoking or other irritants that can contribute to the development of oral thrush.
