Q. A 28-year-old woman presents to the medical outpatient department with complaints of constant fatigue, weight loss, and feeling hot. She also mentions experiencing lighter menstrual periods and frequent bowel movements for the past few months. On physical examination, her skin is moist, and her eyes appear slightly protruded. Her vital signs are stable, but her heart rate is 105 beats per minute. Lab investigations show a TSH level of 0.1 mIU/L and free T4 of 2.5 ng/dL. What is the most appropriate initial management for this patient?
