Question

Elizabeth, a 12-year-old girl, suffers from indigestion every time she consumes dairy products like milk and cheese. However, dairy consumption has never triggered an immune response in her. In this case, the reason for such physiological reaction is most likely due to _____.

a. food allergy
b. anaphylaxis
c. edema
d. food intolerance

Answer 1

Elizabeth likely suffers from lactose intolerance, a digestive issue due to insufficient lactase enzyme production, which is different from a food allergy.

Step-by-step explanation:

The correct answer is d. food intolerance. Elizabeth's indigestion after consuming dairy products without an immune response indicates lactose intolerance. It is a condition that occurs when the small intestine does not produce enough lactase, the enzyme necessary for the digestion of lactose, the sugar found in milk and dairy products. This is different from a food allergy, which involves an immune response, and is also not related to anaphylaxis or edema, both of which are associated with allergic reactions and not digestive enzyme deficiencies.

Lactose intolerance can cause symptoms such as bloating, gas, and diarrhea after consuming lactose-containing foods. Treatment options include avoiding dairy, using lactose-free products, or taking lactase supplements to aid digestion. This condition is common in certain populations and can develop with age as the ability to produce lactase commonly decreases.
