Fructosuria

Definition

Definition of Fructosuria
This disorder is also known as essential fructosuria and hereditary fructosuria often seen in children. It is caused by a hepatic fructokinase deficiency which leads to excretion of fructose in urine. Fructosuria is a benign condition, since fructose is not broken down to glucose; it is simply excreted out of the system in urine. Fructosuria is unlike Fructosemia which means fructose in the blood. The latter is a more serious condition that can cause growth abnormalities and even coma in some severe cases. Unlike fructosuria, fructose in Fructosemia is converted to fructose-1-phosphate which uses up the body's ATP stores. This will prevent the proper release of glucose from glycogen, uses up the free phosphate available in the body, and causes uric acid levels to rise.

Symptoms

Symptoms of Fructosuria
Symptoms of Fructosuria include the presence of fructose in the urine. Symptoms of hypoglycemia are also manifested by the individual.

Causes

Causes of Fructosuria
Essential fructosuria is caused by a hepatic fructokinase deficiency. Without this enzyme, fructose is not further broken down into glucose which the body can use. The unmetabolized fructose remains intact and excreted through urine.

Diagnosis

Diagnosis of Fructosuria
Diagnosis is done through urinalysis where the urine will be positive for fructose.

Prognosis

Prognosis of Fructosuria
The prognosis of Fructosuria usually refers to the likely outcome of Fructosuria. The prognosis of Fructosuria may include the duration of Fructosuria, chances of complications of Fructosuria, probable outcomes, prospects for recovery, recovery period for Fructosuria, survival rates, death rates, and other outcome possibilities in the overall prognosis of Fructosuria. Naturally, such forecast issues are by their nature unpredictable.

Treatment

Treatment of Fructosuria
Treatment for Fructosuria involves eliminating sources of the sugar from the diet. By reducing and restricting the amount of fructose ingested, the amount of fructose present in the urine will also decrease.
