Fruktózmalabszorpció

Fructosemalabsorption, also known as fructose malabsorption, is a condition characterized by the inability to absorb fructose, a simple sugar, from the intestines. This condition is often associated with hereditary fructose intolerance, a rare genetic disorder. In hereditary fructose intolerance, the liver lacks the enzyme necessary to break down fructose, leading to its accumulation and subsequent toxicity.

Fructosemalabsorption can also occur as an isolated condition, where the intestines fail to absorb fructose but the liver can metabolize it. This can be due to a variety of factors, including genetic mutations, infections, or other medical conditions.

Symptoms of fructosemalabsorption may include abdominal pain, bloating, and diarrhea, particularly after consuming fructose-rich foods or beverages. In severe cases, it can lead to more serious complications such as liver failure or kidney damage.

Diagnosis of fructosemalabsorption typically involves a combination of medical history, physical examination, and specific tests. These may include a hydrogen breath test, which measures the amount of hydrogen gas in the breath after consuming a fructose-rich beverage, or a genetic test to identify any underlying genetic mutations.

Treatment for fructosemalabsorption focuses on avoiding fructose and other simple sugars. This may involve a strict diet, avoiding foods high in fructose such as fruits, honey, and certain vegetables, as well as beverages like fruit juices and soda. In cases of hereditary fructose intolerance, a low-fructose diet is essential to prevent liver damage. In some cases, medications may be prescribed to manage symptoms or prevent complications.
