Question
What’s the disease when an 18-month-old baby has black tongue coating?
Answer
A baby’s black tongue coating may be caused by extreme heat and fire. For those with gastrointestinal issues, the tongue coating might become thick and greasy, starting as white and gradually turning yellow or black. In clinical practice, it has been observed that some chronic diseases, such as uremia and malignant tumors, may also appear with black tongue coating when the condition worsens, which is usually a sign of a critical illness and immediate medical consultation should be sought.
