B2hiány

B2hiány refers to a deficiency in vitamin B2, also known as riboflavin. This vitamin is essential for various metabolic processes in the body, including energy production, cell growth, and the breakdown of fats, drugs, and steroids. Riboflavin is water-soluble, meaning the body does not store large amounts of it, and a regular dietary intake is necessary.

Symptoms of B2hiány can develop gradually and may include cracks at the corners of the mouth (cheilosis), inflammation of the tongue (glossitis), and skin rashes, particularly around the nose and ears. Other signs can involve sensitivity to light, blurred vision, and a sore throat. In more severe cases, neurological issues can arise, though this is rare.

The causes of B2hiány are typically related to inadequate dietary intake. This can occur in individuals with restricted diets, malnutrition, or certain eating disorders. Alcoholism can also impair riboflavin absorption. Medical conditions affecting nutrient absorption in the gut, such as celiac disease or inflammatory bowel disease, can contribute to the deficiency.

Diagnosis is usually based on clinical symptoms and a history of inadequate dietary intake. Blood tests can measure riboflavin levels, but these are not always readily available or routinely performed.

Treatment involves increasing riboflavin intake through diet or supplements. Foods rich in vitamin B2 include milk and dairy products, eggs, leafy green vegetables, lean meats, and fortified cereals. Oral supplements are effective in correcting the deficiency. Once treated, symptoms usually resolve within a few weeks. Prevention focuses on maintaining a balanced diet that includes sufficient sources of vitamin B2.
