Fructose malabsorption

Fructose malabsorption is a food intolerance based on mutations of the SLC2A5 gene. If fructose is not absorbed by the intestinal brush border cells osmotic diarrhea results which can lead to chronic inflammation and morphological alterations.

Symptoms

Diarrhea
The ingestion of large amounts of fructose may induce diarrhea in patients with fructose malabsorption.
