Brief Summary
Malnutrition is a pathological condition in which dietary intake fails to meet the body's energetic or nutritional needs. It may be caused by macronutrient or micronutrient deficiencies, high energy expenditure, impaired nutrient absorption or assimilation. Malnutrition can affect all stages of life. In adults, malnutrition is strongly associated with poor clinical outcomes such as increased morbidity, increased mortality and prolonged hospitalization. In children, malnutrition can lead to growth retardation, cognitive impairment and immune dysfunction.
