Fructose intolerance is also called as fructose malabsorption. It is a condition which is characterized by the absence of an enzyme called Aldolase B which is responsible for the conversion of fructose into glucose. In people with fructose intolerance, the food which contains fructose will be retained in the inner organs causing complications of liver function. The only way to avoid this situation is by not taking the foods which contain fructose.
People with fructose mal-absorption will have frequent diarrhea, constipation, bloating sensation and flatulence. There may be mild to severe forms of abdominal pain and in some people there may be mild depression. More commonly, the individuals with fructose intolerance will have restricted or irritable bowel movements.
There may be increase in blood sugar level, due to the accumulation of sugar in blood. It may also lead to kidney failure in infants and may even cause death. In infants, the parents have to look for symptoms of poor intake of feeding and the child may become irritable during feeding. Excess of sleeping and convulsions are also observed in some children. Vomiting and jaundice are more common when the liver gets affected due to fructose intolerance.
Heredity is the main cause for fructose mal-absorption. Usually the deficiency of particular enzyme which converts the fructose into glucose is seen in affected children. In some cases, the rate of conversion may occur partially also.
Some people may develop fructose indigestion. They may not be able to digest fructose completely leaving traces of fructose in blood. This may cause bloated sensation and cause gastric problem with abdominal pain.
The only method of treatment available for this disease is to avoid taking foods which contain fructose. The affected child or person should minimize or totally avoid the intake of fructose content in any form of food. Honey and fruits contain large quantities of fructose. It is also found in many beverages. Food rich in fructanes should be avoided.
