Multiple Choice

Which of the following statements is true of lactose intolerance?

Lactose intolerance is an autoimmune disorder affecting the small intestine.

Lactose intolerance is a condition that primarily affects the liver's ability to process lactose.

Lactose intolerance results from the inability to digest lactose due to low levels of lactase enzyme.

Lactose intolerance is caused by an overproduction of lactase enzyme.

Verified step by step guidance

Begin by understanding what lactose intolerance is. It is a digestive disorder caused by the inability to break down lactose, a sugar found in milk and dairy products.

Identify the role of lactase enzyme. Lactase is produced in the small intestine and is responsible for breaking down lactose into glucose and galactose, which can be absorbed into the bloodstream.

Recognize the cause of lactose intolerance. It occurs when the small intestine produces low levels of lactase enzyme, leading to undigested lactose in the digestive system.

Evaluate the statements provided. The statement 'Lactose intolerance results from the inability to digest lactose due to low levels of lactase enzyme' accurately describes the condition.

Understand that lactose intolerance is not an autoimmune disorder, does not primarily affect the liver, and is not caused by an overproduction of lactase enzyme.
