What is the best method to treat hyperthyroidism?

Hyperthyroidism can initially be treated with medication under a doctor's guidance, and symptoms often improve or even resolve completely. If there is no improvement, the patient should seek medical treatment at a hospital to prevent worsening of the condition. Patients with hyperthyroidism should ensure adequate rest, avoid straining their eyes by using electronic devices such as smartphones and computers, and refrain from smoking. If blood counts and liver function are normal, oral antithyroid medications such as methimazole may be taken. Liver function should be monitored regularly, and drug dosages adjusted or reduced accordingly.
