Description

Hereditary fructose intolerance (HFI) is an inherited disorder caused by a deficiency of the enzyme aldolase B, which is necessary for the metabolism of fructose. People with HFI are unable to break down fructose, a sugar found in many fruits, vegetables, and sweeteners. When fructose is consumed, it accumulates in the liver and other organs, leading to a variety of symptoms, including abdominal pain, vomiting, and diarrhea. In severe cases, HFI can cause liver failure and even death. Treatment for HFI involves avoiding foods and beverages that contain fructose, as well as taking medications to help the body break down fructose.
