A pregnant patient with hyperthyroidism may require which of the following treatments?

In the context of treating hyperthyroidism during pregnancy, beta-blockers are commonly used to manage symptoms such as tachycardia, anxiety, and tremors that may occur due to increased thyroid hormone levels. They are effective in alleviating the hyperadrenergic symptoms of hyperthyroidism and can be used safely in pregnant patients, particularly when the benefits outweigh the risks.

Beta-blockers, like propranolol, can help control heart rate and provide symptomatic relief without significant adverse effects on the fetus when used at appropriate dosages. They do not address the underlying hyperthyroidism but help manage the symptoms effectively, making them a suitable option in this situation.

The other treatments listed, such as radioactive iodine therapy and thyroidectomy, are generally not recommended during pregnancy due to potential risks to the fetus. Radioactive iodine can have teratogenic effects and should be avoided, while a thyroidectomy is usually reserved for severe cases of hyperthyroidism or when other treatments have failed. Strict dietary modifications alone are often insufficient to manage hyperthyroidism and do not address the physiological symptoms that beta-blockers can help control. Therefore, the use of beta-blockers is appropriate and effective for symptomatic relief in pregnant patients with hyperthyroidism.
