Nutrition in Internal Medicine

Nutritional support has become a part of patient treatment. The nutritional content varies depending on the underlying disease in each patient. Malnutrition is defined as a condition that arises due to inadequate or excessive nutrition. Malnutrition is a major contributor to both morbidity and mortality, with its risk significantly heightened in hospitalized patients. Early assessment of a patient's nutritional status and timely appropriate treatment initiation can effectively reduce morbidity and mortality rates. As malnutrition is preventable, identifying at-risk patients and providing adequate nutritional support are essential components in optimizing clinical outcomes. Therefore, this review summarizes the nutritional approach to some common diseases in internal medicine practice. Our review's recommendations are based on guidelines from the European Society for Clinical Nutrition and Metabolism (ESPEN).
