Fructose intolerance, also know as fructose malabsorption is an irritating and sometimes troublesome problem.
Due to a problem in the small intestine fructose isn’t absorbed into the bloodstream, instead the undigested fructose is carried to the colon where it is subject to a socalles “unaeroob”digestion in which bacteria rapidly devour it. In the process, the bacteria produce gases and acid which cause the intestine to swell. This is experienced by the person as the known symptoms of fructose intolerance: bloating, cramping, gas and distention. Diarrhea may also occur.
What are the symptoms of fructose malabsorption?
Onset of symptoms can occur at any age. Symptoms vary depending on the person and the amount of fructose they have eaten. Some people can tolerate much more fructose than others. The most common symptoms are bloating, gas, cramping and diarrhea. When diarrhea occurs over prolonged periods, nutrient deficiencies and their symptoms may appear. The most common nutrients affected are folic acid, zinc, iron, tryptophan, calcium, vitamin c and e. Elevated blood levels of amylase and lipase-enzymes from the pancreas- may also be seen. Some people may also experience symptoms such as fatigue, headaches, brain fog, mood changes and constipation.
