Question

Cheilosis is a physical symptom associated with a deficiency of

1: vitamin D.
2: folic acid.
3: riboflavin.
4: vitamin C.

Answer 1

Cheilosis is a sign of riboflavin (vitamin B2) deficiency, manifesting as sores on the lips and other symptoms, and should not be confused with vitamin C deficiency, which causes scurvy.

Step-by-step explanation:

Cheilosis is a symptom associated with a deficiency of riboflavin, also known as vitamin B2, not vitamin C. It presents as characteristic lesions on the lips, including fissures at the angles of the mouth. In contrast, a deficiency of vitamin C leads to scurvy, which is characterized by symptoms such as bleeding gums, nosebleeds, fragile capillaries leading to a tendency to hemorrhage, and poor healing due to collagen formation impairment. A diet lacking sufficient vitamin C can indeed lead to serious health issues, but to address cheilosis specifically, one should look at vitamin B2 levels.

Cracks or sores on the lips, redness of the tongue, and dermatitis are signs of cheilosis. It is important to include foods rich in riboflavin in one's diet to prevent such deficiency diseases. Foods such as dairy products, eggs, lean meats, nuts, and green vegetables are good sources of vitamin B2.
