Graves' disease was the underlying cause in 69% of cases, toxic multi nodular goiter in 29%, and toxic adenoma and sub acute thyroiditis in 1% each. Palpitations, tremor, weight loss and nervousness were the commonest presenting manifestations. Forty-five (45%) of patients were treated with antithyroid drugs, 36% with radioactive iodine and 18% underwent subtotal thyroidectomy. Post radiotherapy hypothyroidism developed in 37% of patients.ConclusionCauses and clinical manifestations of thyrotoxicosis in our patients were comparable with those reported in the literature. There is under use of radioactive iodine therapy, and physicians should be encouraged to use this mode of therapy as its efficacy, safety and low cost made it the preferred definitive treatment in most patients with hyperthyroidism.
