If hyperthyroidism is caused by medication, it can be corrected by reducing the medication. However, if it is not caused by drugs, it may always be hyperthyroidism, which requires regular treatment. Hypothyroidism needs to take levothyroxine sodium for lifelong replacement therapy, but if the dose of the drug is too large during the medication, it will cause palpitations, excessive sweating, fear of heat, emaciation and other symptoms of hyperthyroidism, which belong to the medication hyperthyroidism. It is recommended to go to the hospital in time for consultation and treatment, and can be completely corrected after adjusting the dosage of the drug according to the doctor’s guidance. If the symptoms of hyperthyroidism are not relieved after adjusting the dosage or even stopping the medication, or even if thyrotropin receptor antibodies are detected in the test, hyperthyroidism caused by autoimmune thyroid disease should be considered. Medications such as methimazole and propylthiouracil or radioactive iodine therapy are needed to help control the condition under the advice of a doctor. When symptoms of hypothyroidism or hyperthyroidism appear, it is recommended to consult a doctor and cooperate with him/her for treatment.
