A 50 year old obese man complains of several recent abscesses in the gingiva with loosening of teeth. He also suffers from itching of skin and polyuria. The most probable etiology is______________?

Correct answer: C. Diabetes mellitus

A. Scurvy
B. Myxoedema
C. Diabetes mellitus
D. Vitamin A deficiency

Explanation

Polyuria, pruritus and recurrent infections or gingival abscesses strongly suggest diabetes mellitus, where hyperglycaemia impairs host defence and wound healing. Scurvy can loosen teeth but does not explain the polyuria and itching together.
