Evaluation and Investigation of Thyroid Disease

The document discussed functional disorders of the thyroid gland, specifically hypothyroidism and hyperthyroidism. Hypothyroidism was often caused by chronic autoimmune thyroiditis and iodine deficiency, with symptoms such as fatigue, weight gain, and hair loss. Hyperthyroidism presented with symptoms like weight loss, anxiety, and palpitations. Physical examination for hypothyroidism revealed signs like dry skin and bradycardia, while hyperthyroidism was associated with thin skin and muscle weakness. Thyroid nodules were typically solitary but could also be part of a multinodular goitre.
