Which conditions are associated with Vitamin B6 deficiency?

Vitamin B6 deficiency is notably associated with a variety of physiological impacts, particularly affecting the skin and mucous membranes. In this context, cheilosis, or "chelitis," which manifests as cracks and lesions at the corners of the mouth, and glossitis, characterized by inflammation and changes in the tongue's surface, are both indicative of this deficiency.

Cheilosis and glossitis occur due to the crucial role vitamin B6 plays in amino acid metabolism and the overall synthesis of neurotransmitters and hemoglobin. When there is an inadequate supply of vitamin B6 in the body, these areas can become inflamed or damaged, leading to the symptoms observed.

While other options contain symptoms that may also indicate various nutrient deficiencies or health issues, they do not specifically highlight the primary symptoms associated with vitamin B6 deficiency. Therefore, the choice that includes both cheilosis and glossitis aligns accurately with what is clinically observed in cases of vitamin B6 deficiency.
