Unintentional weight loss of more than 10% in 6 months is considered which level of malnutrition?

• A. Mild
• B. Severe
• C. Moderate
• D. Critical

Answer: (C)

Unintentional weight loss expressed as a percentage of usual body weight over a defined period is a key way to gauge malnutrition severity. A loss greater than 10% in six months shows substantial depletion of energy and protein stores, which fits the moderate malnutrition category. This level signals a meaningful nutritional problem that requires assessment and intervention to prevent further decline, and it sits between mild and the more severe states. Extremely large or rapid losses with additional clinical signs would indicate severe or critical malnutrition.
