A patient who has hypothyroidism can live a full and normal life if he is:

• A. Taught the importance of taking his antithyroid medication until it is no longer needed.
• B. Able to exercise to burn extra calories and maintain a normal weight.
• C. Taught to take care of his energy needs through adequate nutrition.
• D. Treated with thyroid replacement therapy.

Answer: (D)

The key idea is that restoring the missing thyroid hormone is what lets a person with hypothyroidism live a normal, active life. When the body lacks enough thyroid hormone, metabolism slows, causing fatigue, weight gain, cold intolerance, constipation, and mood changes. Replacing the hormone with thyroid replacement therapy—usually synthetic levothyroxine—replenishes T4 (which is converted to the active T3 in tissues) and normalizes the metabolic rate. With proper dosing and regular monitoring of TSH and free T4, most people experience improvement in energy, weight, and overall function, and can lead a normal, active life. Over time, doses may need adjustment to avoid tipping into hyperthyroidism, which can cause palpitations, anxiety, or insomnia. Options suggesting antithyroid medication would worsen hypothyroidism rather than treat it, and while exercise and good nutrition support health, they don’t correct the underlying hormone deficiency.
