Clinical impact of identifying lactose maldigestion or fructose malabsorption in irritable bowel syndrome or other conditions.
"CONCLUSIONS: Carbohydrate maldigestion has a similar incidence in patients with and without IBS and both populations have similar compliance with therapeutic diets. However, patients without IBS are more likely to have improvement in symptoms when dietary changes are instituted when compared to IBS patients."
Fructose intolerance in IBS and utility of fructose-restricted diet.
CONCLUSIONS: About one-third of patients with suspected IBS had fructose intolerance. When compliant, symptoms improved on fructose-restricted diet despite moderate impact on lifestyle; noncompliance was associated with persistent symptoms. Fructose intolerance is another jigsaw piece of the IBS puzzle that may respond to dietary modification.
