Abstract

Malnutrition is a highly prevalent and well-recognized problem in hospitalized as well as in general population but often goes unrecognized. Nutrition assessment is a comprehensive approach to define nutritional status using various methods. Subjective Global Assessment (SGA) is one of the most commonly used methods to assess nutritional status. SGA is a semiquantitative tool to assess nutritional status based on the history and physical examination. Data are scored subjectively and determine nutritional status in three major SGA categories as well nourished (A), mild to moderately malnourished (B), or severely malnourished (C). It is simple, noninvasive, inexpensive, and quickly executable and can be performed bedside by any skilled and trained health-care professional after brief training. It also agreeably goes with the objective methods of evaluating nutritional status. Various modified versions of SGA have been proposed since its conception to improve its precision. It helps in identifying malnutrition, predicting outcomes, and making appropriate recommendations in hospitalized patients as well as in general population.
