Multiple Choice

Which statement accurately describes lactose intolerance?

Lactose intolerance is a condition where the stomach produces too much acid.

Lactose intolerance is caused by an allergic reaction to lactose.

Lactose intolerance is a genetic disorder that affects the absorption of all sugars.

Lactose intolerance results from the inability to produce enough lactase enzyme.

Verified step by step guidance

Understand that lactose intolerance is related to the digestion of lactose, a sugar found in milk and dairy products.

Recognize that the enzyme lactase is responsible for breaking down lactose into glucose and galactose, which can then be absorbed by the body.

Identify that lactose intolerance occurs when the body does not produce enough lactase enzyme, leading to undigested lactose in the digestive system.

Note that undigested lactose can cause symptoms such as bloating, gas, and diarrhea, as it is fermented by bacteria in the colon.

Conclude that lactose intolerance is not related to stomach acid production, allergies, or the absorption of all sugars, but specifically to the deficiency of lactase enzyme.
