Detailed explanation-1: -Disaccharidase deficiency can cause malabsorption of carbohydrates. The unabsorbed sugars can serve as an osmotic load in the small bowel, drawing fluid into the lumen and leading to intestinal distension and rapid propulsion into the colon.

Detailed explanation-2: -Disaccharidase deficiency: Deficiency of the enzymes in the small intestine that break down disaccharides such as lactose, sucrose and maltose (i.e. deficiency of lactase, sucrase, and maltase). Symptoms include flatulence, bloating, stomach pain, nausea and diarrhea.

Detailed explanation-3: -Lactase deficiency is the most common disaccharidase deficiency and may be primary or secondary.
