Which statement best describes the symptom profile commonly associated with hypothyroidism?

• A. Memory impairment
• B. Intolerance to cold
• C. Difficulty breathing
• D. Decreased blood pressure

Answer: (B)

When thyroid hormone levels are low, the body's metabolism slows down, so less heat is produced. That makes people with hypothyroidism feel colder more easily, a classic sign of the condition. This cold intolerance tends to sit alongside fatigue, weight gain, and dry skin, forming the typical symptom picture.

Memory impairment can occur because cognitive processing slows with low metabolism, but it’s not as specific or central a feature as cold intolerance. Difficulty breathing isn’t a defining symptom of uncomplicated hypothyroidism, and decreased blood pressure isn’t the hallmark finding—hypothyroidism more often brings bradycardia and may have normal or only mildly elevated diastolic pressure. So, cold intolerance best describes the common symptom profile.
