It is determined by the body's relative nutritional requirements as well as its capacity to digest and absorb them. It is assessed using anthropometric, biochemical, clinical, and dietary approaches (also known as the ABCDs of nutritional evaluation). Anthropometrics involves measuring the height, weight, bone mass, muscle mass, etc. of an individual. Biochemical tests analyze the amount of specific substances in the blood or other tissues that are associated with health or disease. Clinical examinations look at internal organs such as the heart or lungs while dietary assessments involve asking questions about what type of food is eaten and how much of it is consumed over a certain period of time. These methods are all used to determine an individual's nutritional status. The American College of Nutrition recommends that before adopting any intervention strategy for patients with diabetes, nutrition professionals should assess the patient's overall nutritional status through a combination of anthropometric, biochemical, and clinical measures along with information from the patient's diet and lifestyle. This assessment will help identify patients who may be at risk for poor outcomes due to malnutrition and guide potential interventions. Malnutrition increases the risk of mortality, morbidity, and disability after a stroke. Therefore, it is important for physicians to screen their patients for malnutrition following a stroke. The most effective method for screening is still under debate but there are several tools available for use.
