Fructose intoleranceWhat is fructose intolerance?
Hereditary fructose intolerance is an inborn metabolic disorder based on an enzyme deficiency which is necessary for proper metabolism of ingested fructose. It is an autosomal recessive mutation in the gene ALDOB (aldolase B). In case of enzyme deficiency, fructose can not be metabolised completely leading to fructose-1-phosphate (an intermediate) accumulation. High amounts of accumulated fructose-1-phosphate then cause liver cell death.
What are symptoms of fructose intolerance?
Hypoglycemia, vomiting, abdominal pain and irritability
