Which symptom is commonly seen in hypothyroidism?

Explanation:
Hypothyroidism slows the body's overall metabolism, and thyroid hormones help regulate heart rate. When thyroid hormone is deficient, the metabolic and sympathetic influences on the heart diminish, leading to a slower resting heart rate, or bradycardia. This is a common sign of hypothyroidism. The other options reflect hyperthyroid effects—weight loss from increased metabolism, heat intolerance from excess heat production, and tremors from heightened neuromuscular activity—so they don't fit as well with hypothyroidism.
