Is thyroid nodule caused by hyperthyroidism or hypothyroidism?

Although hyperthyroidism, hypothyroidism and thyroid nodules are all diseases on the thyroid gland, there is a big difference between them. These three diseases are not the same disease at all, and they all have their own symptoms and their own treatment methods. The former two diseases, hyperthyroidism and hypothyroidism, are relative diseases, both of which are caused by abnormal secretion of thyroid hormones, and they are also autoimmune diseases. The latter, thyroid nodule, is an organic lesion, and a large part of thyroid nodule is thyroid cancer. All three diseases are thyroid diseases, so there will be abnormal secretion of thyroxine, but in the end they will show different clinical symptoms because of their different causes. Let's introduce these three diseases respectively. First, hyperthyroidism < P > Hyperthyroidism, also known as hyperthyroidism, is caused by excessive thyroid secretion, and hyperthyroidism also has a certain family genetic tendency. Because thyroid hormone is a very important hormone used to promote one's own metabolism, when thyroid hormone is secreted too much, its metabolism will be hyperactive and nerves will become excited. Because metabolism becomes faster, people need to eat a lot, which in turn leads to increased gastrointestinal burden, enhanced activity and more excretion times. Because its body consumes more energy than before, people will gradually lose weight even if they eat more. Moreover, according to everyone's different physique, some patients will sweat a lot and have a low fever.

Moreover, because of the excessive secretion of thyroid hormones, they usually have uncontrollable emotions. They are very easily excited or irritable, and some people will have palpitations and tachycardia. Of course, some people will have mental problems such as anxiety and insomnia. If not treated in time, it will develop diseases such as heart disease. Hyperthyroidism will not only affect the heart, but also affect the eyes, causing eyelid edema and even some people's fundus will be damaged to some extent. There are also symptoms such as injury to the lower limbs, edema of the lower limbs and thickening and roughening of the skin. Second, hypothyroidism < P > Hypothyroidism is different from hyperthyroidism, and it is just the opposite of hyperthyroidism. Hypothyroidism is also called hypothyroidism, that is, thyroid hormone secretion is lower than normal level. Of course, there is also a situation in which one's own resistance to the action of thyroid hormone will make one's own organs, or the metabolism in the body decline. The difference between hypothyroidism and hyperthyroidism is that hyperthyroidism is obvious, but hypothyroidism is not obvious, so even hypothyroidism is not easy to be found. Many patients have no special performance when they are sick.

When the patient begins to be afraid of cold, drowsiness and swelling of hands and feet, as long as the symptoms that are not manifested by other diseases are excluded, it can basically be concluded that he has hypothyroidism. Because hypothyroidism is also an autoimmune disease, it is not particularly easy to treat. With hypothyroidism, the skin of the whole body will also thicken and dry, and a lot of hair will fall off. Not only that, because of the low secretion of thyroid hormone, there will be symptoms such as slow response and indifferent expression, and some people will even become dementia patients. Because of slow metabolism, there will be bradycardia, anorexia, amenorrhea and other symptoms. If you suffer from hypothyroidism when you are young, it will also affect your own development.

3. Thyroid nodules

Thyroid nodules are more frightening than hyperthyroidism and hypothyroidism. They are organic lesions and may develop into thyroid cancer. Thyroid nodule is a long lump in the thyroid gland, which will move up and down with swallowing. The mass caused by this organic disease, except for some benign and non-developing, is easy to change and then develop into cancer.

However, whether you are suffering from hyperthyroidism, hypothyroidism or thyroid nodules, don't blindly define your illness. Be sure to go to the hospital to ask the doctor and follow the doctor's advice.
