Which of the following might be a consequence of untreated riboflavin deficiency?

Untreated riboflavin deficiency can lead to a variety of health issues, and delayed wound healing is one of the noted consequences. Riboflavin, also known as vitamin B2, plays a critical role in the body's metabolic processes, particularly in the production of energy and the metabolism of fats, drugs, and steroids. It also contributes to the maintenance of healthy mucous membranes, skin, and vision.

When riboflavin levels are insufficient, the body's ability to repair and heal tissues can be compromised. This delay in wound healing can be attributed to the vitamin's role in cellular respiration and the synthesis of antioxidants, both of which are vital in the wound healing process. Adequate riboflavin is necessary for the proliferation and maintenance of various cell types, including those involved in the healing process.

Other potential effects of riboflavin deficiency are generally associated with different health conditions rather than specifically impairing wound healing. Thus, while those health issues could theoretically occur, they are not as directly linked to the deficiency as impaired wound healing is. This makes delayed wound healing the most appropriate consequence to highlight in the context of riboflavin deficiency.
