Graves’ disease
This is the most common cause and is an autoimmune condition in which the body’s immune system mistakenly targets the thyroid gland and causes it to produce too much thyroid hormone. It is unclear what triggers this condition however, there is a genetic basis for Graves’ disease, meaning that it often runs in families. It is most common in women aged 20-40 and has a higher incidence amongst smokers.
Nodular thyroid disease
Lumps can develop in the thyroid gland. They are known as nodules. It is unclear why they develop, and they are usually benign. The thyroid is usually enlarged, but there is no pain. Nodules may be felt with the fingertips and are often found on physical examination. The nodules can contain abnormal thyroid tissue, affecting the regular function of the thyroid, causing overactive thyroid. Nodules that contain abnormal thyroid tissue are described as toxic.
Excessive iodine intake
The thyroid gland removes iodine from the blood which comes from foods such as seafood, bread, and salt. It then uses the iodine to produce thyroid hormones. The two most important thyroid hormones are thyroxine (T4) and triiodothyronine (T3). Taking additional iodine in supplements can cause the thyroid gland to produce too much of the hormones. Intake of thyroid hormones – lack of regular patient blood work and follow-up can result in patients not adjusting their thyroid medications as their needs change.
Medications
Certain medications used in the treatment of heart problems contain a large amount of iodine and thus may be associated with changes in thyroid function. An example is amiodarone, which is sometimes prescribed for patients with atrial fibrillation.Other medications, like lithium for bipolar disorder, have been known to cause hyper- or hypothyroidism.
Thyroiditis
This is an inflammation of the thyroid; it is often the result of a viral infection. The signs and symptoms may include fever, sore throat, painful swallowing, generalized aches, and pains in the neck.
Follicular thyroid cancer
In rare cases, overactive thyroid can be caused by thyroid cancer. The malignant cells may themselves start producing thyroxine or triiodothyronine.
