Sinus Infection and Oral Thrush
Sinus infection could lead to a person having oral thrush due to overprescription of
antibiotics for its treatment.
What is Oral Thrush?
Oral thrush, medically known as Oral Candidiasis, is caused by the Candida Ablicans yeast-like
organism. Normally, this organism is present in the oral cavities and gastrointestinal tract in a healthy adult
without posing any health problems. However, when the balance between this organism and other bacteria in the body
is not in equilibrium, the organism multiplies in numbers leading to a fungi infection.
Causes of Oral Thrush
1. Over-consumption of antibiotics and other types of medication.
Doctors often prescribe antibiotics to patients who are found suffering from a bacterial sinus
infection. These antibiotics will not only eliminate the bad bacteria but also the good bacteria in us which does
not cause us any harm.
When the good bacteria within our oral cavities are destroyed by the antibiotics, the Candida
Ablicans yeast which is not affected, start to multiply uncontrollably.
Long-term consumption of oral and inhaled corticosteroids can also lead to oral thrush.
2. Weakened immune system.
Our body’s natural immune system can sometimes be compromised and impaired due to stress,
serious illnesses such as cancer, AIDS, and other fungal infections including fungal sinusitis or fungal sinus infection.
Oral Thrush Symptoms
The most evident symptom of oral thrush is the appearance of curd-like yellow spots in the
mouth. Accidental scraping off these spots will cause slight bleeding and the area looks raw.
In adults, oral thrush causes an uncomfortable burning sensation in the mouth and throat.
Sometimes oral thrush may not present itself with yellow spots. This is especially so when the
infection is at the back of the throat. When this happens, the back of the throat will look inflamed, red and slightly swollen.
There will be a lot of pain and discomfort felt when you drink and swallow food while eating.
You may suspect oral thrush if a sore throat does not go away within a week and linger on for a month.
Oral Thrush Treatment
Most ENT doctors would prescribe Nyastatin oral suspension. This is a very effective antifungal
medication and must be taken a directed for a complete cure. Having a diet of yoghurt and consuming lactobacillus
acidophilus in sufficient quantities can aid in the recovery process.
Sinus Infection and Oral Thrush
Why would a sinus infection lead to oral thrush? First of all, it is common for doctors to
prescribe antibiotics for sinus infections since early cure for this condition is imperative in order to nip it in
Unless a culture is taken, which could prove costly to the patient, most doctors would prescribe
a broad-spectrum antibiotic such as Amoxicillin. This antibiotic will usually work unless the bacterium is
resistant to it. But in some cases, a patient with a really low immune system may require a stronger dose of
The patient then fails to recover and would need a second course of stronger antibiotics to
treat the sinus infection.
Naturally, the good bacteria in the oral cavity die off due to the overconsumption of
antibiotics paving the road for an oral thrush infection.
A healthy adult can usually take two to three courses of antibiotics without developing
oral thrush. But when one gets oral thrush, it strongly indicates that the person has a very low immune
system and he should take immediate steps to improve his health.
