Which symptom is associated with hypothyroidism in children?

• A. Weight loss
• B. Fatigue
• C. Hyperactivity
• D. Elevated cholesterol

Answer: (B)

Low thyroid hormone slows the body's metabolism, so children with hypothyroidism often feel unusually tired and have less energy for activities. This fatigue—persistent tiredness and lethargy—is a common and noticeable symptom in kids with hypothyroidism because their bodies aren’t burning energy as they should. Weight changes can occur, but weight loss is not typical; many children may even gain weight due to the slowed metabolism. Hyperactivity would not fit, since hypothyroidism tends to reduce energy and activity levels. Elevated cholesterol can appear as a lab finding, but it’s less immediate as a symptom kids notice. So fatigue best captures how hypothyroidism typically presents in children.
