Hereditary fructose intolerance

Hereditary fructose intolerance (HFI) is an inherited disease characterized by nausea, abdominal pain, diarrhea, vomiting, low blood sugar, and liver and kidney damage. It involves defects in making the enzyme aldolase B, which is responsible for breaking down fructose (a sugar found primarily in fruit) into a form used by the body for energy. View testing options
