When lactose intolerance is due to secondary lactase deficiency, treatment of the underlying disease may allow lactase activity to return to normal levels. [6] In people with celiac disease, lactose intolerance normally reverts or improves several months after starting a gluten-free diet , but temporary dietary restriction of lactose may be needed.
However, better tests have become available with greater ease of use, better sensitivity and specificity for the causative conditions. Tests are also needed to detect the systemic effects of deficiency of the malabsorbed nutrients (such as anaemia with vitamin B12 malabsorption). [citation needed]

Lactose intolerance is a result of the body not producing sufficient lactase to digest the lactose in milk; [25] [26] dairy foods which are lower in lactose, such as cheese, are less likely to trigger a reaction in this case. Another carbohydrate intolerance caused by enzyme deficiency is hereditary fructose intolerance.
One common example of food intolerance is lactose intolerance. Metabolic food reactions are due to an inborn or acquired errors of metabolism of nutrients such as in diabetes mellitus, lactase deficiency, phenylketonuria and favism. Toxic food reactions are caused by the direct action of a food or additive without immune involvement. [15]
Lactose is a disaccharide sugar composed of galactose and glucose that is found in milk. Lactose can not be absorbed by the intestine and needs to be split in the small intestine into galactose and glucose by the enzyme called lactase; unabsorbed lactose can cause abdominal pain, bloating, diarrhea, gas, and nausea. [citation needed]
Not all questions have simple, yes or no answers—including this one. While many dogs are lactose intolerant, many are not! Lactose intolerance develops as a dog grows up, so it can be impossible ...
D-xylose absorption test is a medical test performed to diagnose conditions that present with malabsorption of the proximal small intestine [1] due to defects in the integrity of the gastrointestinal mucosa. [2] D-xylose is a monosaccharide, or simple sugar, that does not require enzymes for digestion prior to absorption. Its absorption ...
