1- Coated tongue
Yellow coating on the tongue can be an indication of a liver or gallbladder disease. Another possible cause is leukoplakia. This condition causes white patches or plaques to form on the tongue, and it often results from smoking.
Caution: Smoking falsifies this finding.
2- Light, white coating
Typical of a cold, but also occurs in the long term with gastritis (inflammation of the stomach lining). White coating on the back of the tongue (tongue base) is a typical sign of scarlet fever. A pronounced whitish coating can also mean that yeasts of the type Candida albicans have spread in the oral cavity and thrush has formed. The fungus can be treated with an antifungal drug.
3- Strongly demarcated spots
The spots and lines are typical of a map tongue, a harmless appearance without any disease value.
