Xylose (specifically the d-xylose form) is a simple sugar that is easily absorbed by our body.
This test determines if our body absorbs xylose well at the intestinal level. The concentrations of xylose in both blood and urine are measured after the administration of a specific amount of xylose in order to determine the absorption capacity of carbohydrates in general, to detect problems of malabsorption of sugars present in the diet. This test is recommended when there are symptoms related to malabsorption such as diarrhea, feeling of heaviness in the stomach or gas.
