What symptom suggests malnutrition?

• A. Hair loss
• B. Fatigue
• C. Headache
• D. Weight loss

Answer: (D)

Unintended weight loss is a direct sign of malnutrition because when intake is inadequate or nutrients aren’t absorbed properly, the body begins to break down its fat and lean tissue to meet energy and nutrient needs, leading to a measurable loss of body weight. Other symptoms like hair loss, fatigue, or headaches can occur for many reasons and are not as specific to malnutrition on their own; they may be seen with other conditions, whereas a noticeable drop in weight more clearly reflects insufficient nutrition. In clinical practice, tracking weight over time and noting unexplained loss helps identify malnutrition early.
