Primary hyperthyroidism can be cured, but the course of antithyroid medication may be relatively long, and most patients may stop taking the medication completely only after about 1.5-2 years of treatment. Therefore, it is necessary for patients to adhere to the medication as prescribed by the doctor, not to stop or reduce the medication arbitrarily during the treatment process, to review regularly, to adjust the dosage of thyroid medication, and to observe whether serious side effects such as granulocyte deficiency and liver damage will occur during the treatment process. If the review is relatively frequent, side effects can be detected early and the dose of medication can be adjusted early. If the course of anti-thyroid medication is not enough, unauthorized discontinuation of the medication will be particularly prone to relapse. Therefore, before discontinuing the medication, it should be carefully evaluated by the doctor to observe whether the conditions for discontinuation are met before deciding whether to discontinue or reduce the medication, and must not be discontinued or reduced without authorization. During the course of treatment, we should adjust our dietary habits, including low iodine or iodine-free diet, regular work and rest, positive and optimistic attitude towards the disease, and regular review with the doctor, so that primary hyperthyroidism can be cured as soon as possible and is less likely to recur.
