Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
In
hyperthyroidism thyroid gland becomes overactive and makes too much thyroid hormone. Variety of diseases such as immune system disorders and endocrine system disorders may cause overactive thyroid along with thyroid gland disorders. High thyroid hormone levels in the body may cause rapid heartbeat, atrial fibrillation,
profuse sweating, weight loss anxiety and tiredness. Treatment depends on an exact cause of hyperthyroidism.
Methimazole is an antithyroid medicine that used to treat mostly Graves' disease or toxic
nodular goiter. If methimazole fails to control thyroid hormone levels, I usually advise my patients
radioactive iodine ablation therapy. It is a permanent treatment option in which radioactive iodine is given to a patient and thyroid gland absorbs the iodine. Radioactive iodine will damage thyroid gland and suppress thyroid hormone production. It may cause side effects if too much thyroid cells get damaged causing
hypothyroidism.
Please, consult with your doctor about iodine ablation therapy.
Hope I have answered your query. Let me know if I can assist you further.
Thank you,
