Clinical Nutritionist Practice Test

Sick individuals may experience malabsorption due to various medical conditions affecting their gastrointestinal (GI) tract, particularly as a result of surgical resection of the intestine. When portions of the intestine are surgically removed, it can significantly reduce the surface area available for nutrient absorption, leading to deficiencies. This is especially relevant in cases of conditions such as Crohn's disease or cancers that necessitate such procedures.

The intestine plays a crucial role in the digestion and absorption of nutrients, and loss of any part of it can disrupt these processes. As a result, individuals may have difficulty absorbing not just macros like proteins, fats, and carbohydrates, but also essential vitamins and minerals.

Other scenarios related to malabsorption can stem from conditions that alter the intestinal mucosal lining or impair digestion as a whole, but surgical resection directly impacts the structure and function of the GI tract.
