Weight history is part of which SGA category?

• A. Imaging
• B. Laboratory Data
• C. Physical Exam
• D. Historical

Answer: (D)

Weight history is a patient-reported piece of information that describes changes in weight over time, including recent unintentional weight loss, its duration, and whether the change was intentional. In SGA, this kind of information is collected under the Historical domain because it comes from interviewing the patient and reflects subjective experience and reported trends. It helps gauge malnutrition risk and its trajectory. Imaging and laboratory data are objective test results, while the Physical Exam looks for observable signs like muscle wasting or edema. So weight history belongs in the Historical section.
