What Causes Thyroid Dysfunctions?

The thyroid gland is located in the neck. This gland produces hormones that help regulate the body’s metabolism and a person’s growth. When the thyroid gland becomes overactive, the person starts feeling anxious and nervous, experiencing severe weight loss. In case the thyroid gland is underactive, the person feels tired and depressed, and he puts on a lot of weight. To better understand the thyroid, you have to understand what are the causes of the malfunctions of this gland. If you want to learn which are these causes, read the following lines.

Toxic adenomas

Thyroid malfunctions can be linked to the development of nodules in the thyroid gland. These nodules begin to secrete thyroid hormones, a fact that upsets the body’s chemical balance. Some goitres may even contain several of these nodules.

Subacute thyroiditis

Another cause of thyroid malfunction is when the thyroid gland is inflamed and it leaks excess hormones. This results in the apparition of temporary hyperthyroidism. Fortunately, it usually lasts only a few weeks, but there are cases in which it persists for months.

Graves’ disease

Graves’ disease causes the production of excessive amounts of thyroid hormone. This ultimately leads to the appearance of hyperthyroidism.

The removal of the thyroid gland

One of the causes of the appearance of hypothyroidism is the removal of the thyroid gland. If the thyroid has been surgically removed or chemically destroyed, you might be in danger of suffering from this thyroid malfunction.

Lithium

Lithium is used in the treatment of mental disorders, eating disorders, blood disorders, alcoholism, liver disease, headache, asthma, arthritis, and many other medical issues. Unfortunately, lithium consumption has been proved to be a cause of hypothyroidism as well. Therefore, you should try to avoid consuming it.

Exposure to excessive amounts of iodine

You are in the risk of developing hypothyroidism if you are exposed to excessive amounts of iodine. The exposure to high amounts of iodine occurs when you take too much cold and sinus medicines, when you take amiodarone, or when you’re exposed to certain contrast dyes given before X-rays. Also, the risk of you developing hypothyroidism when you’re exposed to high amounts of iodine is increased if you have already had thyroid problems in the past.

Hashimoto’s disease

Hashimoto’s disease is an autoimmune disorder in which the body’s own immune system attacks the thyroid tissue. This leads to reduced thyroid hormone. Therefore, it ultimately causes the appearance of hypothyroidism.
