Diabetic Tongue - Could it be a Diagnostic Criterion?

Diabetes mellitus (DM) is a common disease which usually manifests in the form of polyuria, polydipsia, weight loss, fatigue, weakness, blurry vision, frequent skin infections, and slow healing of skin lesions. Taste disturbances like ageusia, hypogeusia and dysgeusia have been associated with DM. The early diagnosis of DM based on these symptoms is very important to start treatment early and thereby prevent complications. We present an interesting case of a female presenting with altered taste as the first symptom of DM.
