Hyperthyroidism is known as the increase in the functioning of the thyroid gland, which in turn generates an increase in the levels of thyroid hormones, in the blood, which has as a consequence an increase in the acceleration of the body's metabolic activity. This is a very common disorder, which affects more than 1% of the world's population, affecting in most cases women whose ages range between 30 and 40 years.
Some of the symptoms that characterize hypothyroidism are tachycardia, weight loss, constant nerves, and tremors in the body. In the case of humans, the main causes of this condition are Graves' disease, toxic thyroid adenoma, toxic multinodular goiter, and the effects of some medications.
The main and most common cause is Graves-Basedow disease. In this pathology there is an appearance of antibodies that stimulate the production of excess hormones. Secondly, there is the appearance of nodular goiters, which lead to the breakdown of the cells that contain thyroxine and that is how they end up in the bloodstream.
Generally, people who are affected by hyperthyroidism have increased arousal in all organs and systems of the body. Such changes occur gradually, reason why initially can be blamed on the stress and nervousness.
In the case of the elderly, on the other hand, it can manifest itself only with fatigue, weight loss and depression; it is called listless hyperthyroidism and is more difficult to detect. In other cases the symptoms appear suddenly at their maximum intensity, which is called a "thyroid storm." Symptoms can include:
- Weight loss: the patient's general body metabolism is increased, therefore he will consume more energy without the need for exercise. For its part, the feeling of hunger increases and you want to eat larger amounts and more frequently.
- Hyperactivity: the state of mind is altered and those affected are restless, they feel the need to perform various activities continuously, regardless of the moment.
