Answer to Question 2
Illnesses and their treatments may lead to malnutrition by causing a reduction in food intake, interfering with digestion and absorption, or altering nutrient metabolism and excretion. For example, the nausea caused by some illnesses or treatments can diminish appetite and reduce food intake; similarly, an inflamed mouth or esophagus may cause discomfort when the patient consumes food. Some medications can cause anorexia or gastrointestinal (GI) discomfort, or interfere with nutrient function and metabolism. Prolonged bed rest often results in pressure sores, which increase metabolic stress and raise protein and energy needs.
