Which symptom is commonly associated with hypothyroidism?

• A. Weight gain
• B. Weight loss
• C. Tachycardia
• D. Heat intolerance

Answer: (A)

Hypothyroidism slows the body's metabolism, so energy expenditure drops. That reduction often leads to weight gain, even if food intake stays the same or increases slightly. This slowing of metabolic rate is a classic feature of hypothyroidism and makes weight gain a common and characteristic symptom. In contrast, a fast heart rate (tachycardia) and heat intolerance are typically seen with hyperthyroidism, where metabolism is heightened, often leading to weight loss rather than gain. So among the options, weight gain best aligns with hypothyroidism and explains the overall metabolic slowdown.
