The treatment of hyperthyroidism in children varies from person to person, and there is no such thing as a “good or bad cure”. Some people are more sensitive to antithyroid medication, which may be relatively effective, while some babies can have their medication dosage adjusted under the guidance of a doctor if necessary if their symptoms are difficult to control. The treatment of hyperthyroidism includes general treatment, antithyroid drugs, symptomatic treatment and so on. 1. General treatment: keep emotionally stable, pay attention to rest, eat a nutritious diet, and avoid eating foods containing more iodine such as seaweed, shrimp and sea fish. 2. Antithyroid medication: Methimazole is preferred, and propylthiouracil can also be used under doctor’s guidance if there are special circumstances. During the treatment, monitor and check the blood routine regularly, pay attention to whether there is leukopenia, and pay attention to whether there are other side effects, such as drug rashes and liver function impairment. 4. Symptomatic treatment: if the heart rate increases obviously, propranolol can be used. If there is a protruding eyeball and other manifestations, oral prednisone treatment can be taken under the guidance of the doctor. Children with hyperthyroidism, parents should take them to the hospital in time, under the guidance of the doctor to standardize the treatment, and regular rechecking of thyroid function, follow the doctor’s instructions to adjust the drug.
