Overactive thyroid gland occurs when the thyroid gland produces a large amount of thyroxin. An overactive thyroid gland may cause an increased metabolism speed, resulting in unintended weight loss and a fast and irregular heartbeat.There are many ways to treat the overactive thyroid gland. Doctors use anti-thyroid drugs and radioiodine to slow the production of thyroid hormone. Sometimes, treatment includes surgery to remove your entire or part of your thyroid gland.Although the overactive thyroid gland may be dangerous if you ignore it, most people respond well once the condition is diagnosed and treated.
1. Causes of an overactive thyroid gland
There are three main diseases responsible for the overactive thyroid gland.
1.1 Graves' disease
Graves 'disease. It is the most common cause of overactive thyroid gland (approximately 90% of cases). It is an autoimmune disease: antibodies overly stimulate the thyroid to produce more hormones. The disease also sometimes attacks other tissues, such as those of the eyes.
1.2 Thyroid nodules
Nodules are small masses that form in the thyroid gland, alone or in a group. Not all nodules produce hormones, but those that do (called "toxic") can cause an overactive thyroid gland.
If inflammation affects the thyroid, it can also cause an excess of thyroid hormones in the blood. Often the cause of the inflammation is unknown. It can be infectious or occur after pregnancy. Usually, thyroiditis causes an overactive thyroid gland of short duration. The thyroid will be regaining its normal functioning after a few months, without intervention. Medication can help relieve symptoms while waiting for the disease to pass.

6. Treatment of an overactive thyroid gland
Depending on the origin and intensity of an overactive thyroid gland. Different treatments will be offered by the endocrinologist.Medications: Some medicines prevent the thyroid gland from producing excessive amounts of hormones, and beta-blocker medications may also be used to immediately control side effects.Radioactive iodine treatment: this treatment destroys some thyroid cells to stop the overproduction of hormones.Surgery: in which the thyroid gland, or part of it, is removed, and when completely removed, the person will need to take thyroid medication for life.
