Tryptophan

Some effects of fructose malabsorption are decreased tryptophan, folic acid and zinc in the blood.
The disorder fructose malabsorption causes improper absorption of tryptophan in the intestine, reduced levels of tryptophan in the blood, and depression.

Fructose malabsorption may cause gastrointestinal symptoms such as abdominal pain, bloating, flatulence or diarrhea.
In persons who have fructose malabsorption, excess fructose intake can also cause diarrhea.

Fructose malabsorption, formerly named "dietary fructose intolerance" (DFI), is a digestive disorder in which absorption of fructose is impaired by deficient fructose carriers in the small intestine's enterocytes.
Fructose malabsorption or Dietary Fructose Intolerance is a dietary disability of the small intestine, where the amount of fructose carrier in enterocytes is deficient.

This abnormal increase in hydrogen may be detectable with the hydrogen breath test.
A hydrogen breath test (or HBT) is used as a diagnostic tool for small intestine bacterial overgrowth and carbohydrate malabsorption, such as lactose, fructose, and sorbitol malabsorption.

Irritable bowel syndrome

IBSbowelirritable bowel
Occurrence in patients identified to be suffering symptoms of irritable bowel syndrome is not higher than occurrence in the normal population.
Reduction of fructose and fructan has been shown to reduce IBS symptoms in a dose-dependent manner in people with fructose malabsorption and IBS.

Foods rich in fructans and other fermentable oligo-, di- and mono-saccharides and polyols (FODMAPs), including artichokes, asparagus, leeks, onions, and wheat-containing products, including breads, cakes, biscuits, breakfast cereals, pies, pastas, pizzas, and wheat noodles.
Fructose malabsorption and lactose intolerance may produce IBS symptoms through the same mechanism but, unlike with other FODMAPs, poor absorption of fructose is found in only a minority and, in certain populations, notably those of European descent, lactose intolerance is found in only a minority.

Coeliac disease

celiac diseasecoeliacceliac
In some cases, fructose malabsorption may be caused by several diseases which cause intestinal damage, such as celiac disease.
A careful interpretation of the symptomatic response is needed, as a lack of response in a person with coeliac disease may be due to continued ingestion of small amounts of gluten, either voluntary or inadvertent, or be due to other commonly associated conditions such as small intestinal bacterial overgrowth (SIBO), lactose intolerance, fructose, sucrose, and sorbitol malabsorption, exocrine pancreatic insufficiency, and microscopic colitis, among others.

Enterocyte

Fructose malabsorption, formerly named "dietary fructose intolerance" (DFI), is a digestive disorder in which absorption of fructose is impaired by deficient fructose carriers in the small intestine's enterocytes.
Dietary fructose intolerance occurs when there is a deficiency in the amount of fructose carrier.

Hereditary fructose intolerance

Fructose malabsorption is not to be confused with hereditary fructose intolerance, a potentially fatal condition in which the liver enzymes that break up fructose are deficient.

Restricting dietary intake of free fructose and/or fructans may provide symptom relief in a high proportion of patients with functional gut disorders.
