Question

Cheilosis disease and digestive disorders are caused by the deficiency of:

• A. Ascorbic acid
• B. Thiamine
• C. Cyanocobalamine
• D. Riboflavin
• E. Pyridoxine

Hint:

Riboflavin (vitamin B2) is essential for growth, development, and the normal function of the skin and digestive system. Its deficiency can lead to cheilosis and digestive disorders.

Answer 1

The Correct Option is D

Cheilosis is a condition that involves sores, cracks, or ulcers at the corners of the mouth. It is commonly caused by a deficiency of certain vitamins. Along with cheilosis, riboflavin (also known as vitamin B2) deficiency can also lead to digestive disorders.
Step 1: Riboflavin (vitamin B2) plays a key role in energy metabolism, and its deficiency can lead to symptoms like cracks at the corners of the mouth (cheilosis), sore throat, inflammation of the tongue (glossitis), and digestive issues. This makes riboflavin deficiency the correct cause of these symptoms.
Step 2: The other vitamins mentioned are associated with different deficiency-related diseases:
- Ascorbic acid (vitamin C) deficiency causes scurvy, not cheilosis.
- Thiamine (vitamin B1) deficiency leads to beriberi, not cheilosis.
- Cyanocobalamin (vitamin B12) deficiency leads to pernicious anemia.
- Pyridoxine (vitamin B6) deficiency causes neurological issues like peripheral neuropathy.
Thus, the correct answer is option (D), riboflavin.
