Which combination of signs is most characteristic of severe hypothyroidism (myxedema)?

Severe hypothyroidism slows many body systems. The thyroid hormone sets the pace for metabolism, so when it’s deficient the heart tends to beat more slowly (bradycardia), heat production drops and the skin feels cool, and interstitial mucopolysaccharide buildup leads to puffiness, especially in the face (myxedema). This combination—slow heart rate, facial swelling, and cool skin—fits the classic picture of myxedema. The other signs point away from hypothyroidism: hyperactivity with heat intolerance and weight loss suggests excess thyroid hormone; a fasting glucose below normal isn’t a defining feature; and hyperreflexia isn’t typical in hypothyroidism ( reflexes are usually slowed or delayed).
