[4][2][3] Recent research has hinted at a connection between the distribution of taste cells and ACE2 receptors in ageusia.
Higher amounts of the receptors suggests an easy route for a COVID-19 infection with a possible outcome of ageusia.
[9] Ageusia could also possibly occur due to changes in the abundance or lack of saliva that can eventually cause damage to the cells on the tongue's surface.
[8] However, there is still insufficient research to fully clarify the full effects of ageusia, COVID-19, and their potential impacts on saliva and 'salivary flow rate.
As well as imaging of the head and neck, to help further identify or eliminate the presence of tumors, focal lesions, or any type of injury that could possibly be affecting any taste-related networks.
[5][13][14] An otolaryngologist can also conduct a series of tests to assess the severity of ageusia, which includes identifying specific tastes that the patient can sense or recognize.
This test involves applying mild electric currents to specific tongue areas, to assess taste sensitivity in patients exhibiting ageusia and its symptoms.
[5][4] People experiencing ageusia can endure daily discomfort, which frequently diminishes their enjoyment of eating.
When blood sugar levels fluctuate, it can disrupt the taste buds, making it difficult to detect flavors.
