Which of the following is a common cause of Protein-Energy Malnutrition?

A common cause of Protein-Energy Malnutrition in patients, particularly those with kidney issues, is poor nutritional intake due to uremia induced anorexia. Uremia occurs when the kidneys are unable to filter waste products from the blood effectively, leading to a build-up of toxins that can significantly reduce appetite. This loss of appetite can result in insufficient caloric and protein intake, essential for maintaining overall health and body functions. As the body is deprived of necessary nutrients, muscle wasting and depletion of energy stores ensue, culminating in Protein-Energy Malnutrition.

In this context, while hydration levels, fluid intake, and dietary carbohydrate ratios can influence a patient's overall health, they are not direct causes of Protein-Energy Malnutrition in the same way uremia induced anorexia is. These factors may relate more to fluid balance or other metabolic concerns rather than directly leading to a deficiency in protein and energy intake. The primary link in this scenario is how uremia impacts appetite and nutritional consumption, making it crucial to address in patients with renal impairment.
