Explain malabsorption and give an example
What will be an ideal response?
Malabsorption (impairment of absorption) may be caused by damage to or reduction of the surface area of the small intestine. One of the most common causes is gluten enteropathy, also known as celiac disease. In this condition, the person's small intestine is abnormally sensitive to gluten, a protein constituent of wheat, barley, and rye. This condition is a complex immunological disorder in which exposure to gluten erroneously activates a T-cell response that damages the intestinal villi. The normally luxuriant array of villi is reduced, the mucosa becomes flattened, and the brush border becomes short and stubby, which negatively impacts intestinal absorption.
