Causes of Hyperthyroidism

Hyperthyroidism can have many causes like thyroiditis, thyroid nodules, inflammation of the thyroid, etc. In very rare cases, hyperthyroidism is also caused by a non-cancerous tumor of the pituitary gland. If you consume too much iodine, then it can make your thyroid hormones shoot up as well.

Grave’s Disease

It is one of the most common causes of hyperthyroidism. The Grave’s disorder is an autoimmune disorder. The immune system takes thyroid as an enemy and attacks it. The attack causes the thyroid gland to over-produce the thyroid hormone.


This problem occurs when the thyroid gets inflamed. This causes the thyroid hormone to leak out of the gland. The hyperthyroidism can last up to 3 months. After three months, it becomes underactive and goes into hypothyroidism. It can last you about 12-18 months, but in some cases, it could be permanent.

Overactive Thyroid Nodules

They are lumps in your throat that are usually benign. Benign means that they are not cancerous. However, these nodules can become overactive. Hence, it produces too much thyroid hormone. However, this condition mostly occurs in older adults.

Too much Iodine

Iodine is used to make thyroid hormone. So if you consume a lot of iodine, it will affect thyroid hormone production. In some cases, over-consumption of iodine has caused the thyroid to produce too much hormone.

Too much Thyroid Medicine

If a patient is not well-informed about the dosage of the medicine that he should consume, he could go overboard. This is why it is important to go see your doctor regularly. The doctor will make any changes necessary in the dosage of the medicine. There are some other medicines also that could raise the hormone levels.

Treatment Options

Thus, it relieves uncomfortable symptoms. The symptoms might vary from one person to another. Therefore, the same treatment will not work for everyone.

The treatment depends on the cause of hyperthyroidism. And also it depends on the condition of mild or severe it is. Your doctor will consider your age, sex, possible allergies, and other conditions like heart problems or even pregnancies.

Medication Dosage

It is often difficult to look out for symptoms of hyperthyroidism. It is so because the symptoms like fatigue, diarrhea, or muscle weakness could be passed off as normal issues. If you are experiencing any of the above-mentioned symptoms without cause, see a doctor.

If left untreated, it could lead to serious problems. In most of the cases, the doctors prescribe a medicine that you have to take in the morning. It is important that you keep visiting the doctor even after the medicine has been prescribed.
