Hereditary Fructose Intolerance

Hereditary fructose intolerance is a genetic disorder in which the body cannot properly process fructose, a sugar present in fruits, honey, and many foods, due to the absence of a specific enzyme.

Common symptoms: After consuming fructose, nausea, vomiting, abdominal pain, sweating, and malaise may appear; in young children, a refusal of sweet foods may be noticed.

Common causes: It is hereditary in origin and shows up when foods containing fructose are introduced into the diet.

Which specialist treats it? Follow-up of hereditary fructose intolerance is usually shared between the pediatrician and the dietitian, who provide guidance on the appropriate diet. With symptoms related to certain foods, consulting these professionals is very helpful.
