  2. Fructose malabsorption - Wikipedia

    en.wikipedia.org/wiki/Fructose_malabsorption

    Fructose malabsorption, formerly named dietary fructose intolerance (DFI), is a digestive disorder [1] in which absorption of fructose is impaired by deficient fructose carriers in the small intestine's enterocytes. This results in an increased concentration of fructose. Intolerance to fructose was first identified and reported in 1956. [2]

  3. Hereditary fructose intolerance - Wikipedia

    en.wikipedia.org/.../Hereditary_fructose_intolerance

    After ingestion, fructose is converted to fructose-1-phosphate in the liver by fructokinase. Deficiencies of fructokinase cause essential fructosuria, a clinically benign condition characterized by the excretion of unmetabolized fructose in the urine. Fructose-1-phosphate is metabolized by aldolase B into dihydroxyacetone phosphate and ...

    Hereditary fructose intolerance (HFI) results in poor feeding, failure to thrive, chronic liver disease and chronic kidney disease, and death. HFI is caused by a deficiency of fructose 1,6-biphosphate aldolase in the liver, kidney cortex and small intestine. Infants and adults are asymptomatic unless they ingest fructose or sucrose.

    en.wikipedia.org/wiki/Fructose_intolerance

    Fructose intolerance may refer to: Fructose malabsorption , a digestive disorder of the small intestine in which the fructose carrier in enterocytes is deficient Hereditary fructose intolerance , a hereditary condition caused by a deficiency of liver enzymes that metabolise fructose

  6. Food intolerance - Wikipedia

    en.wikipedia.org/wiki/Food_intolerance

    This mechanism causes allergies to typically give immediate reaction (a few minutes to a few hours) to foods. Food intolerances can be classified according to their mechanism. Intolerance can result from the absence of specific chemicals or enzymes needed to digest a food substance, as in hereditary fructose intolerance.

  7. Essential fructosuria - Wikipedia

    en.wikipedia.org/wiki/Essential_fructosuria

    The amount of fructose routinely lost in urine is quite small. [6] Other errors in fructose metabolism have greater clinical significance. Hereditary fructose intolerance, or the presence of fructose in the blood (fructosemia), is caused by a deficiency of aldolase B, the second enzyme involved in the metabolism of fructose. [citation needed]

  9. FODMAP - Wikipedia

    en.wikipedia.org/wiki/FODMAP

    Fructose malabsorption and lactose intolerance may produce IBS symptoms through the same mechanism, but unlike other FODMAPs, poor absorption of fructose is found in only a minority of people. Lactose intolerance is found in most adults, except for specific geographic populations, notably those of European descent. [20]
