Hyperthyroidism Risk Factors
If you are a woman, your chances of developing hyperthyroidism (an overactive thyroid) are 5 to 10 times greater than that of a man. Other risk factors for hyperthyroidism relate to medical conditions you may have, such as type 1 diabetes, or lifestyle decisions you make, such as smoking.
What Are Some Risk Factors for Hyperthyroidism?Hyperthyroidism is when a person's thyroid makes an excess of thyroid hormones relative to the body's needs. It can be caused by a number of different conditions or situations (see Hyperthyroidism Causes).
There are also factors that can increase a person's chances for developing hyperthyroidism. These are known as hyperthyroidism risk factors.
One risk factor is being a woman. Women are 5 to 10 times more likely than men to develop hyperthyroidism. Other people at risk for an overactive thyroid include those with:
- A previous thyroid problem, such as goiter
- A previous history of thyroid surgery
- Type 1 diabetes
- Primary adrenal insufficiency
- A family history of thyroid disease
- Pernicious anemia.
Risk factors also include those people:
- Who eat large amounts of food containing iodine, such as kelp, or use iodine-containing medications, such as amiodarone, a heart medication
- Are older than 60 years of age
