Riboflavin deficiency causes which of the following diseases ?

Riboflavin, also known as Vitamin B2, is a water-soluble vitamin essential for energy metabolism and cellular function. Its deficiency, termed ariboflavinosis, manifests through specific clinical symptoms:

• Cheilosis: This is a hallmark sign of riboflavin deficiency, characterized by inflammation and painful cracking or fissures at the corners of the mouth (angular stomatitis) and on the lips.
• Pellagra: This disease is caused by a deficiency of Niacin (Vitamin B3), often characterized by the "four Ds": dermatitis, diarrhea, dementia, and death.
• Scurvy: This results from a lack of Vitamin C (Ascorbic acid), leading to bleeding gums and poor wound healing.
• Beri Beri: This is caused by a deficiency of Thiamine (Vitamin B1), affecting the cardiovascular or nervous systems.

Other symptoms of riboflavin deficiency include glossitis (swollen, magenta-colored tongue) and seborrheic dermatitis.
