Tag: Purple tongue

Approximately 1 in 4 people admitted to a hospital may have a nutritional deficiency, and sometimes the tongue can reveal these issues. A change in tongue color is one such indicator, and understanding what vitamin deficiency causes a purple tongue is a crucial first step toward addressing an underlying health concern.

While a healthy tongue is typically a uniform pink color, an unusual purple or bluish hue can sometimes signal an underlying health issue, ranging from minor deficiencies to serious conditions affecting oxygen levels. It is not always caused by a deficiency and could stem from other more serious health concerns.
