ariboflavinózis

Ariboflavinosis is the medical term for vitamin B2 deficiency, also known as riboflavin deficiency. Riboflavin, or vitamin B2, is an essential nutrient that plays a crucial role in various metabolic processes, including energy production, cell growth, and the metabolism of fats, drugs, and steroids.

Ariboflavinosis typically develops when dietary intake of riboflavin is insufficient or when absorption is impaired. Common causes include restrictive diets, alcoholism, malabsorption syndromes, and certain medical conditions. Symptoms can vary in severity and may include inflammation of the skin, particularly around the mouth and nose, known as cheilosis and nasolabial seborrheic dermatitis, respectively. Other common signs include glossitis (inflammation of the tongue), angular stomatitis (cracks at the corners of the mouth), and conjunctivitis (inflammation of the eye's outer membrane). In some cases, it can also lead to anemia and neurological symptoms.

Diagnosis is usually based on clinical presentation and can be confirmed by laboratory tests measuring riboflavin levels in the blood or urine. Treatment involves increasing riboflavin intake through diet or supplementation. Foods rich in riboflavin include dairy products, eggs, lean meats, green leafy vegetables, and fortified cereals. Supplementation is generally effective in reversing the deficiency and alleviating symptoms. Prevention focuses on maintaining a balanced diet adequate in riboflavin.
