Caviar tongue is most commonly observed among people of older age groups. Most commonly in the 4th-5th decades of life. The scientific reason behind this is that with advancing age the walls of blood vessels (here veins) start thinning out and their elastic fibres are degraded, resulting in their loosening, which leads to increased blood pressure in them. Thus, resulting in a purple-black appearance on the affected surface. When sublingual varicosities are seen in younger age groups it is presented as a sign of early ageing (premature ageing) which may be an indicator of some underlying systemic disease.

Treatment of Caviar Tongue

Caviar Tongue does not need any treatment as such. However, if it is present on the lips or the buccal surface of the mucosa, sclerotherapy or photocoagulation with a high-intensity laser can be performed for aesthetic purposes.

In patients with Vitamin C deficiency, supplements should be taken as prophylactic measures.
