Test for fructose intolerance at the convenience of your home

What is fructose intolerance?

Fruit, vegetables, white sugar, honey and invert sugar not only contain the well-known glucose, but also fructose. Fructose is mainly used as a sweetener in the food industry because of its strong sweetness.

Fructose intolerance is also called fructose malabsorption. It should not be confused with a life-threatening fructose intolerance. Fructose malabsorption is caused by a defect in the GLUT-5 transport protein in the intestinal cell membrane. This defect can be either congenital or acquired. GLUT-5 serves to absorb fructose into the small intestine. However, if the transporter is defective in its function, the fructose is not absorbed. Therefore, fructose enters the large intestine instead of the small intestine. Once in the large intestine, the intestinal bacteria get to work metabolising the fructose. This produces carbon dioxide, hydrogen, methane and short-chain fatty acids. The end products cause discomfort in the gastrointestinal tract.

In common parlance, fructose intolerance is also called fructose intolerance. However, these are two different diseases.
Fructose intolerance is a congenital enzyme defect in which symptoms already appear in infancy:

  • Aversion to foods containing fructose
  • Hypoglycaemia
  • Liver dysfunction

Fructose is normally metabolised in the liver by the enzyme aldolase B and is necessary for regulating blood sugar to avoid hypoglycaemia. However, because the enzyme is defective, fructose increasingly accumulates in the liver. It cannot be broken down and damages the liver cells. Since fructose cannot be converted to avoid low blood sugar levels, it leads to dangerous hypoglycaemia. They lead to shortness of breath and a comatose state. In the worst case, death is to be expected if not intervened in time.

If left untreated, fructose intolerance can have serious consequences.

We test for fructose malabsorption, which is due solely to a defect in the transport protein, which can also occur later in life.

Meanwhile, 33% of adults are affected by fructose intolerance.
