At some point or the other, we have all gone through tongue issues. Tongue colors could signify the presence of an underlying disease. Research has suggested that even COVID can cause a change in tongue colour and appearance. According to the National Institute of Health, this virus has been said to be causing many unprecedented damages to your body. It should be added here that COVID patients are mostly suffering from a symptom of the dry mouth known as Xerostomia, which is regarded as the early symptom or the first symptom for detection. Lately, multiple studies have found that this symptom of dry mouth mostly occurs with a COVID positive patient way before the occurrence of major symptoms like high fever, sore throat or others.
Apart from this, tongue issues give rise to a variety of symptoms which primarily include tongue discoloration or changing of tongue color. In addition to that, there can be alteration in the texture of the tongue and some pain, and you will be surprised to know that all these symptoms must have an affiliation to a disease.
While detecting a disease, we check blood counts, blood pressure, and heart conditions but we often miss out on checking the color of our tongue. We underestimate the power of a small muscular organ like the tongue and its role in indicating the presence of various diseases. Many of us don’t know that the discolouration of our tongue can tell us a lot about our hidden ailments and at present, the most perilous virus which is lurking around us i.e, the Coronavirus.
A tongue may turn red, yellow, or purple and each color may be indicative of a disease that you are currently suffering from or hiding in you. Moreover, it is not unusual for your tongue to have a different color or shade, but it can also mean the presence of infection or other medical conditions. At present, it can be a sign of COVID-19 as well and this is called the COVID tongue.
According to research, quite a number of COVID-19 patients are diagnosed with bumps, inflammation, and swelling of the tongue and those who are asymptomatic may only have symptoms such as loss of taste and smell. Moreover, tongue discoloration can be a good indication or helpful for doctors to diagnose a condition based on the color or appearance of the tongue.
What can be more wonderful than our diseases or inner ailments being detected with ease by just witnessing the changing color of our tongue? I think it’s time to give priority to the study of tongue discoloration in this time of crisis.
Before getting into the details of an unhealthy or disease-prone tongue, it is essential to know more about a healthy tongue and how it looks just to make you feel optimistic about your own health. We are all aware of the fact that the tongue has the ‘strongest muscle in our body’ which enables us to taste any delicacy, swallow, and most importantly talk or communicate.
So, a healthy tongue, we can say, is typically pink in color, varying slightly in darkness and lightness. Along with this, your tongue will definitely hold some small nodules both on the top side and the bottom and they are generally recognized as papillae. Plus, it should be noted that your healthy tongue will have a thin whitish coating on the surface which ultimately helps you to eat and taste your food.

Moreover, among COVID patients, your body won’t be able to produce saliva which otherwise protects you from harmful bacteria/virus present in your body but in case of Coronavirus, it said to attack the oral linings and muscle fibers, and there ACE2 or Angiotensin-Converting Enzyme create a potential route of entry for the virus in your body. In most cases, COVID patients tend to feel dryness or stickiness in their mouth and the tongue may become much thicker than usual and you may also feel a sudden change in tongue sensation. Along with these, some patients can also feel muscle pain while eating or chewing due to the presence of acute ulcer in their mouth and you can notice that all these strange disorders occur in a COVID patient due to a sudden decrease in the quality of saliva whereas the quantity remains intact.
