Hyperthyroidism appears when the thyroid gland is overactive, that is, it secretes too much thyroid hormone, causing the metabolism to speed up. It is a common benign disease, especially in women. Read: World Thyroid Day: Women should pay more attention to their symptoms

Due to hyperthyroidism

The reasons for the appearance of hyperthyroidism are:

Grave-based disease (GBD)

It is the most common cause of hyperthyroidism (60–70%). It is an autoimmune disease in which antibodies are synthesized that stimulate the thyroid gland to grow and produce excess thyroid hormone.

Multinodular (multiple nodules) or nodular goiter

The thyroid contains many lumps that can slowly grow and begin to synthesize excessive thyroid hormone, causing hyperthyroidism. Read: Let’s talk about thyroid disorders

pituitary tumor

This is a rare cause that occurs when a tumor overproduces thyrotropin (TSH), a hormone that stimulates the thyroid gland to produce thyroid hormones in an irregular manner. By synthesizing so many hormones, the thyroid gland becomes less sensitive and resistant to them.


This is a group of symptoms resulting from high concentrations of circulating thyroid hormones. This can be caused by taking too much thyroxine in the form of pills, inflammation and destruction of the thyroid, which involves the temporary release of the hormone into the blood circulation, such as thyroiditis, or an overactive thyroid (hyperthyroidism).


Hyperthyroidism, which is diagnosed through analytical and imaging tests, is treated depending on the cause of the disease, the severity of symptoms, and the age of the patient.

In general, it is addressed with drugs that reduce the levels of thyroid hormones in the blood (synthetic antithyroid drugs) and that also reduce the side effects of these hormones (beta blockers and anxiolytics), says the Hospital Clinic of Barcelona. Report of.
