Oral thrush

Oral thrush: Introduction

Oral thrush is a yeast infection of the mouth that is caused by a fungal microorganism called Candida albicans. Oral thrust is most common in infants and is generally not a serious condition in itself. However, it can be uncomfortable and lead to difficulties with eating or infant feeding if it does not resolve or is not treated. It can also be a symptom of a more serious condition, such as HIV/AIDS or diabetes.

The fungal yeast that causes oral thrush, Candida albicans, normally lives in the mouth in a certain balance with other microorganisms, such as bacteria. However, some factors or conditions may result in an overgrowth of Candida albicans. Candida albicans can also cause a yeast or thrush infection in the vagina, resulting in the exposure of an infant to the infection during the vaginal birthing process. It can also cause an infection in a woman's nipples, which can then be transmitted to an infant's mouth during breastfeeding.

People at risk for oral thrush include those taking strong antibiotics, especially for a long period of time. Antibiotics kill bacteria, which can alter the balance of microorganisms in the mouth and result in a proliferation of yeast.

People with weakened immune systems are also more likely to develop oral thrush and have recurrent bouts of the infection. This includes people with HIV/AIDS or those taking steroid medications or on chemotherapy, which all suppress the immune system. People with diabetes are more likely to develop oral thrush because the elevated level of sugar in the body provide food for yeast and encourage its overgrowth. Other people at risk include the very young and very old and people with ill-fitting dentures.

Oral thrush causes a rash in the mouth which can become sore and painful and cause further problems. For more information on symptoms and complications, refer to symptoms of oral thrush.

Making a diagnosis of oral thrush includes performing a complete medical evaluation and history and physical examination, including an oral exam. Diagnosis is generally made based on the typical appearance of the oral thrush sores and a history of factors that make the infection likely. Diagnostic testing may include taking a small sample or swab of the rash and examining it under a microscope to confirm an overgrowth of the yeast, Candida albicans, which causes the infection.

It is possible that a diagnosis of oral thrush can be missed or delayed because symptoms may be mild. For more information on misdiagnosis, refer to misdiagnosis of oral thrush.

Oral thrush can be successfully treated with an individualized treatment plan that best fits the patient's age, medical history, and addresses underlying risk factors, such as diabetes. Treatment may include improving oral hygiene, eating certain foods, and medication. For more information on treatment, refer to treatment of oral thrush....more »
