Thrush in adults is caused by an overgrowth of the yeast Candida Albicans that can be caused by diabetes, medications, radiation or chemotherapy, immune system disorders, and some oral health conditions. Thrush is a fungal infection that occurs in your mouth and throat.
Although oral thrush can affect anyone, it’s more likely to occur in babies and older adults because they have reduced immunity; in other people with suppressed immune systems or certain health conditions; or people who take certain medications.
Babies, young children and elderly people are at a particularly high risk of developing oral thrush, as are people with certain underlying conditions, including diabetes, an iron deficiency or vitamin B12 deficiency, an underactive thyroid (hypothyroidism) and HIV.
Initially, topical medications are advised; however, if the condition does not go away, the treating clinician may recommend oral antifungal drugs. In adults with immunocompromised conditions, the physician will typically recommend antifungal drugs.
For healthy adults, oral thrush (candidiasis) isn’t anything to worry about. It often goes away by itself or once you take antifungal drugs. In some cases, oral thrush can be sign of an underlying health problem, such as cancer, diabetes, HIV/AIDS, or any other illness or treatment that weakens your immune system.
For example, adults are more likely to develop thrush if they have a history of certain medical conditions, medical treatments, or lifestyle habits that weaken their immune system. In otherwise healthy adults, oral thrush is unlikely to cause serious problems.
Complications of untreated yeast infections If left untreated, vaginal candidiasis will most likely get worse, causing itching, redness, and inflammation in the area surrounding your vagina. This may lead to a skin infection if the inflamed area becomes cracked, or if continual scratching creates open or raw areas.
Oral thrush A person with weakened immunity is more likely to get a fungal infection in the mouth, especially if they have poor oral hygiene. The infection manifests as white bumps on the tongue and inner cheeks.
Key points about thrush It is uncommon in people without underlying conditions. Thrush might cause a cottony feeling in your mouth or a loss of taste. Usually, antifungal medicine can treat thrush. Sometimes untreated thrush may turn into a more serious infection, especially in people who are very ill.
What causes thrush
In many cases, thrush goes away on its own without treatment. A persistent yeast infection may require antifungal medications. These can be taken orally or applied as ointments directly to your mouth. Antifungal rinses are another option for treating thrush.
The incubation period for oral thrush is about two to five days.
