ariboflavinoos

Ariboflavinosis is a nutritional deficiency disease caused by a lack of riboflavin, also known as vitamin B2, in the diet. Riboflavin is an essential nutrient that plays a crucial role in energy production, cellular function, and the metabolism of fats, drugs, and carbohydrates. It is also an antioxidant. A deficiency can develop over time, particularly if dietary intake is consistently low.

Symptoms of ariboflavinosis can include sores or cracks at the corners of the mouth, known as angular cheilitis, and inflammation of the tongue (glossitis). The lips may become swollen and purplish, a condition called cheilosis. Other common signs include a sore throat, redness and scaling of the skin around the nose and ears, and a form of anemia. In some cases, neurological symptoms may also manifest.

Ariboflavinosis is often associated with diets that are low in riboflavin-rich foods such as dairy products, lean meats, eggs, leafy green vegetables, and fortified cereals. Alcoholism, malabsorption disorders, and certain medical conditions that affect nutrient utilization can also contribute to its development. Diagnosis is typically based on clinical signs and symptoms, and sometimes confirmed by blood tests measuring riboflavin levels.

Treatment involves increasing riboflavin intake through dietary changes or supplements. Symptoms usually improve rapidly once riboflavin levels are restored. Severe or prolonged deficiency can have more serious health consequences, but it is generally preventable and treatable with adequate nutrition. Public health initiatives that promote fortified foods have significantly reduced the incidence of this deficiency in many populations.
