Hyperthyroidism or an overactive thyroid gland is a condition when your thyroid gland produces too much thyroid hormone. Normally, your thyroid gland produces hormones, known as T3 and T4 hormones that regulate various bodily functions.

In hyperthyroidism, your thyroid gland produces thyroid hormones more than your body requires, which disrupts the normal activities of your body. It can accelerate the metabolism of your body, leading to unintentional weight loss, fast heartbeat, and other symptoms.

The treatment of hyperthyroidism is not complex. It is simple and often effective. The healthcare providers will prescribe medications that can help lower the concentration of thyroid hormone in your body. In this way, adverse symptoms of the health condition also subside.

Along with medications, the healthcare providers may perform surgery to remove a part or whole thyroid gland. If left untreated, hyperthyroidism can become a serious health condition. Therefore you should not ignore it. If you have any symptoms of hyperthyroidism, you should visit the healthcare provider soon.

What Are The Causes of Hyperthyroidism?

Hyperthyroidism is a condition when your body produces too much thyroid hormone. It can occur due to various conditions such as Grave’s disease, thyroiditis, and Plummer’s disease.

The thyroid gland is located in your neck. It produces thyroid hormones that regulate various bodily functions. Sometimes, the concentration of thyroxine hormone may get raised due to conditions such as:

  • Grave’s Disease- an autoimmune disorder in which your immune system produces antibodies that cause your thyroid hormone to produce more hormones.
  • Hyperfunctioning thyroid nodules, known as toxic adenoma, toxic multinodular goiter, or Plummer’s disease. They are conditions when one or more adenomas of the thyroid gland produce too much thyroid hormone.
  • Thyroiditis- sometimes inflammation of the thyroid gland can occur, leading to too much secretion of thyroid hormone. It may occur for no reason. Sometimes thyroiditis can be painful, and sometimes it is not.

What Are The Risk Factors for Hyperthyroidism?

Factors that can increase the risk of hyperthyroidism are:

  • Having a family history of thyroid disease or especially Grave’s disease
