Oral Thrush

What is Oral Thrush?

Oral thrush is a common yeast infection caused by a fungus called Candida. This infection can occur in the mouth and throat, leading to various uncomfortable symptoms. People who wear dentures or use corticosteroid inhalers are at an increased risk of developing oral thrush.

Symptoms of Oral Thrush:

• Burning sensation in the mouth
• Cracks in the corners of the mouth
• Loss of taste
• Oral pain
• Redness inside the mouth and throat
• Unpleasant taste
• White patches in the mouth that may cause mild bleeding when wiped off

If left untreated, the fungal infection can spread to other areas of the body, such as the brain, liver, and heart, by entering the bloodstream.

Diagnosing Oral Thrush:

Oral thrush can be diagnosed based on clinical signs, such as the presence of white blotches in the mouth. In some cases, a sample of the lesion may be taken and examined under a microscope. Your doctor may also perform a blood test to identify any underlying medical conditions that may make you more susceptible to oral thrush.

If you are experiencing symptoms of oral thrush, particularly if they affect your ability to eat or drink, it is crucial to consult your doctor for a proper diagnosis and to determine the most appropriate treatment.

Causes and Risk Factors of Oral Thrush:

Oral thrush occurs when the natural fungus Candida multiplies excessively. Several factors can increase your risk of developing oral thrush, including:

• Diabetes
• Dry mouth caused by a medical condition or treatment
• HIV
• Iron deficiency
• Poor oral hygiene
• Smoking
• Taking antibiotics
• Underactive thyroid
• Undergoing radiotherapy or chemotherapy for cancer treatment
• Using inhaled corticosteroids (preventer asthma inhalers)
• Vitamin B12 deficiency
• Wearing ill-fitting dentures

While Candida can be passed between adults through activities like kissing, it is unlikely to cause an infection unless the individual is already at risk of developing the condition. Therefore, it is advisable to avoid kissing or engaging in oral sex until the infection has completely cleared.

Oral thrush can also be transmitted from mother to infant during breastfeeding. In such cases, both the mother and child should be treated accordingly.

Preventing Oral Thrush:

Practicing good hygiene is key to preventing oral thrush. Follow these preventive measures:

• Brush your teeth and floss daily, especially if you are at an increased risk of developing the condition.
• Rinse your mouth after using a corticosteroid inhaler to clear the medicine and prevent the accumulation of thrush-causing fungi.
• Reduce your consumption of yeast-containing food and beverages, such as beer, bread, and wine, to help prevent the development of oral thrush.

If you experience recurring episodes of oral thrush, it is important to consult your doctor. They may recommend tests to identify any underlying conditions that may contribute to your increased risk of developing oral thrush.

Treatment Options for Oral Thrush:

Several antifungal medicines are available for the treatment of oral thrush. These medications work by targeting and eliminating the Candida fungus cells responsible for the infection. Commonly prescribed antifungal treatments include:

• Nystan Oral Suspension
• Fluconazole
• Daktarin Oral Gel 

It is important to consult your online prescriber or pharmacist to determine the most appropriate treatment option for your specific case. They can provide guidance and information about potential side effects or interactions with other medications.

Factors such as weakened immune systems, certain medications (such as antibiotics or corticosteroids), poor oral hygiene, and underlying medical conditions can increase the risk of developing oral thrush.
