Question

A man complains of diarrhea and stomach ache whenever he consumes dairy products. However, these ailments do not occur when he consumes foods other than dairy products. He is suffering from the deficiency of which of these enzymes?

• A. Renin
• B. Trypsin
• C. Lactase
• D. Lipase

Answer 1

The correct option is C

Lactase

It is a case of lack of the enzyme lactase in the small intestine. Lactase is needed to digest lactose, a sugar found in milk and most other dairy products and also used as an ingredient in other foods. Although most people are born with the ability to make adequate amounts of lactase, the production of lactase normally decreases with age, and there are significant differences in lactase production among ethnic groups. The most common symptoms of lactase deficiency are diarrhea, bloating, and gas. Treatment usually involves avoiding lactose in the diet and management, as there is no cure for the disorder
