D-xylose is a monosaccharide, or simple sugar, that does not require enzymes for digestion prior to absorption.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your D - Xylose Absorption. Your doctor will give specific instructions depending on your condition on how to prepare for D - Xylose Absorption.
It is imperative to be fasting 8 to 12 hours before this test.
