What is Hyperthyroidism?
Hyperthyroidism happens when the thyroid gland makes too much hormone . Hyperthyroidism speeds up body metabolism. If hypothyroidism isn’t treated it can cause of a serious health problem.
Causes of Hyperthyroidism
There are various possible causes of hyperthyroidism, including the below.
1. Graves’ disease
Graves’ disease is an autoimmune condition and the most common cause of hyperthyroidism. It is unclear what triggers Graves’ disease, but it often runs in families, suggesting a genetic basis. The condition can affect the eyes, causing protracted eyelids, bulging eyes, double vision, and swelling around the eyes.
2. Nodular thyroid disease
Thyroid nodules are lumps that develop in the thyroid gland. It is unclear why they occur.
3. Excessive iodine intake
The thyroid gland removes iodine from the blood. Iodine comes from certain foods, such as seafood, bread, and salt. The thyroid gland uses the iodine to produce thyroid hormones. Taking additional iodine in supplements can cause the thyroid gland to produce too many of the hormones. People who take thyroid hormones as medication should follow up regularly with their doctor to make sure they are taking the right doses.
4. Medications
Some medications that treat heart problems contain a large amount of iodine, which may trigger changes in thyroid function. One drug that can affect thyroid function in this way is amiodarone, a drug doctors use to treat an irregular heartbeat.
