Once diagnosed, fructose intolerance can be successfully treated by eliminating fructose from the diet. Patients usually respond within three to four weeks and can make a complete recovery if fructose-containing foods are avoided.

∙ 13y agoHereditary fructose intolerance is a rare genetic disorder in which the body lacks the enzyme needed to break down fructose, causing a buildup of toxic byproducts. This can lead to symptoms like nausea, vomiting, abdominal pain, and low blood sugar levels after ingesting fructose. Treatment involves following a strict fructose-free diet.

Hereditary fructose intolerance is caused by a genetic mutation in the ALDOB gene. This mutation impairs the enzyme aldolase B, which is necessary for metabolizing fructose. When fructose is not properly metabolized, it can lead to a buildup of toxic byproducts and cause symptoms such as nausea, vomiting, and hypoglycemia.
Hereditary fructose intolerance is a genetic condition, so it cannot be prevented. Management of the condition involves avoiding foods and beverages that contain fructose or sucrose, as well as following a strict diet plan to prevent symptoms. Genetic counseling may be helpful for individuals with a family history of the condition.
Hereditary fructose intolerance is usually diagnosed through genetic testing to identify mutations in the aldolase B gene. Additionally, a diagnosis can be confirmed through a fructose challenge test where symptoms are monitored after ingesting fructose. Blood tests measuring specific enzymes levels may also be used to support a diagnosis.
Proximal renal tubular acidosis (type 2) is caused by hereditary diseases, such as Fanconi's syndrome, fructose intolerance, and Lowe's syndrome.
If the condition is not recognized and the diet is not well controlled, death can occur in infants or young children. With a well-controlled diet, the child can develop normally.
Fanconi's syndrome caused secondarily by the genetic diseases galactosemia, glycogen storage disease, hereditary fructose intolerance, and tyrosinemia is prevented by appropriate dietary restrictions to treat the genetic disease.
Hereditary fructose intolerance (HFI) is a rare genetic disorder that affects individuals of all populations. It is typically diagnosed in infancy or early childhood, but can affect people of any age. The prevalence of HFI varies globally, with higher rates reported in certain regions such as Central Europe and the Middle East.
Initial symptoms include vomiting, dehydration, and unexplained fever. Other symptoms include extreme thirst and excessive urination and sweating. There will also be a loss of appetite and a failure to grow. Tremors and seizures caused by low.

Because the degree of lactose intolerance varies so much, treatment should be tailored for the individual.
