According to a study published in Future Medicine, corona virus-2(SARS-CoV-2), a beta coronavirus that causes Covid-19, can affect your salivary gland function. As a result, the quality and quantity of saliva might significantly reduce, leading to dry mouth or xerostomia.
How to Identify It
Check whether it antecedes or precedes other symptoms. Besides Covid-19, dry mouth is a symptom of type 1 diabetes, autoimmune diseases, renal failure and hyperthyroidism. While xerostomia triggered by other conditions comes after other symptoms, xerostomia caused by Covid precedes common symptoms of the infection.
What Other Signs Can Crop Up with It
Other signs that can occur alongside dry mouth include reduced or lost sense of taste, bad breath and a burning tongue.
