What causes hyperthyroidism?

- A family history of thyroid disease or autoimmune disease can also increase your risk.
- Certain medicines , such as heart medicines used to help you heart beat normally, can cause hyperthyroidism.
- Infections near the thyroid gland may damage the gland.
- Other thyroid problems such as an enlarged or swollen thyroid, lumps caused by infections, or thyroid cancer can affect how your thyroid works.
