    A 76-year-old man has had fatigue and loss of interest in daily activities over the past 4 months. He sleeps poorly and has had a 4.5-kg (10-lb) weight loss during this period. He states that he has probably lived long enough. His blood pressure is 110/78 mm Hg, and pulse is 68/min. Examination shows a slow return of deep tendon reflexes. Measurement of which of the following serum levels is the most appropriate next step in management?

    A ) Calcium

    B ) Creatinine

    C ) Glucose

    D ) Testosterone

    E ) Thyroid-stimulating hormone

    If its E, but why weight gain?

    one of the most noticeable symptoms of hypothyroidism is weight gain and difficulty losing extra weight.
