Hereditary Fructose Intolerance (HFI) is a rare genetic disorder that affects the body's ability to metabolize fructose, a type of sugar found in many fruits and sweeteners. It is inherited in an autosomal recessive manner, meaning both parents must carry the gene for their child to be affected. The prevalence of Hereditary Fructose Intolerance varies among different populations.
What is the prevalence of Hereditary Fructose Intolerance?
Prevalence of Hereditary Fructose Intolerance: how many people are affected worldwide, differences by sex and region, with sources.
Hereditary Fructose Intolerance (HFI) is a rare genetic disorder that affects the body's ability to metabolize fructose, a type of sugar found in many fruits and sweeteners. It is inherited in an autosomal recessive manner, meaning both parents must carry the gene for their child to be affected.
The prevalence of Hereditary Fructose Intolerance varies among different populations. In Caucasian populations, it is estimated to affect approximately 1 in 20,000 individuals. However, the prevalence may be higher in certain regions or communities with a higher frequency of carriers.
HFI can present in infancy or early childhood when fructose-containing foods or beverages are introduced. Symptoms may include severe abdominal pain, vomiting, failure to thrive, and hypoglycemia. If left untreated, it can lead to serious complications.
Early diagnosis and strict dietary management are crucial for individuals with HFI to avoid fructose and related sugars. A healthcare professional, such as a geneticist or gastroenterologist, can provide appropriate guidance and support for managing the condition.
