Which vitamin deficiency is indicated by symptoms such as sore throat and glossitis?

The correct choice, indicating that sore throat and glossitis are associated with deficiency in Vitamin B2 (riboflavin), is based on the role this vitamin plays in maintaining healthy mucous membranes and overall oral health. Riboflavin is crucial for the production of red blood cells and helps in the metabolism of fats, drugs, and steroids. A deficiency can manifest in symptoms like soreness of the throat and inflammation of the tongue, known as glossitis, which can present as a swollen, painful, and discolored tongue.

Moreover, riboflavin deficiency can also lead to other oral symptoms such as angular cheilitis and cracks at the corners of the mouth. Recognizing this connection is essential for understanding the broader implications of nutrient deficiencies on mucosal health. This understanding helps in diagnosing the underlying causes of oral discomfort in patients and emphasizes the importance of dietary intake of essential vitamins like riboflavin.
