MTM Pediatric Obesity Practice Test

In the context of orlistat therapy for obesity, what nutrient consideration should clinicians monitor?

Fat-soluble vitamins (A, D, E, and K) due to potential malabsorption Water-soluble vitamins exclusively No nutritional monitoring is needed Excess intake of calcium as the primary concern

Correct Answer:

Fat-soluble vitamins (A, D, E, and K) due to potential malabsorption

Explanation:

Orlistat blocks the digestion and absorption of fat by inhibiting pancreatic lipase. This not only reduces fat intake but also diminishes absorption of fat-soluble vitamins A, D, E, and K, which depend on dietary fat. Because of this, clinicians should monitor levels of these fat-soluble vitamins and consider supplementation if deficiencies arise. Water-soluble vitamins aren’t the primary concern here, and monitoring calcium or no monitoring at all would miss the key risk of fat-soluble vitamin malabsorption.
