Abstract excerpt

BACKGROUND: Lactose malabsorption (LM), the inability to break down lactose into glucose and galactose, is due to a deficiency in the small intestinal lactase phlorizin hydrolase enzyme. Ethnic and geographic variations of LM are known. OBJECTIVE: The aim of this study was to compare the frequency of LM in healthy southern and northern Indian populations. DESIGN: A total of 153 healthy volunteers (76 from...
