In the human body, there is an organ shaped like a butterfly, which is located below the neck thyroid cartilage and on both sides of the trachea. It can move up and down with the throat when swallowed. We call this magical organ the “thyroid”. The thyroid gland controls how fast it uses energy, makes proteins, and regulates the body’s sensitivity to other hormones, all of which depend on the thyroid hormones it makes.
Body Function Regulator
The thyroid gland is the largest endocrine gland of the human body. The “product” produced by this “factory” is thyroxine, but most of the “product” will not be released directly into the blood, but will be stored in the thyroid “depot”-the follicle. . For thyroxine to work, it must first be released from the “warehouse” into the blood. Its effects include promoting energy metabolism throughout the body, promoting physical and intellectual development, and increasing neural excitement.
There are two main types of thyroxine: tetraiodothyroxine (T4) and triiodothyroxine (T3). The “warehouse” stores T4. After T4 is released into the blood, it removes an iodine in the body to become T3, and then T3 and T4 work together to regulate various body functions. It can be seen that the thyroid is the “regulator” that regulates the body’s functions.
In humans, the content of triiodothyroxine is 1/10 of that of tetraiodothyroxine, but its activity is about 3 to 5 times that of tetraiodothyroxine. Therefore, although the amount of triiodothyroxine is large, the effect of triiodothyroxine is more Strong, so most of the regulatory effects are dominated by triiodothyroxine.
More hyperthyroidism, less hypothyroidism
Normal doses of thyroxine are of great significance to children’s growth and development; too much thyroid hormone will cause the three major nutrients to be decomposed in large quantities, causing weight loss. Seeing this, I guess someone will say excitedly: “I have a special idea …” Yes, I know you think of “weight loss”, but this is absolutely necessary!
Excessive thyroid hormone does cause weight loss, but hyperthyroidism symptoms such as rapid heartbeat, headaches, insomnia, irritability, irritability, emotional excitement, nervousness, muscle weakness, muscle atrophy, etc. will follow. These are still mild. If the heart is overloaded for a long time, it can cause hyperthyroidism and heart disease. Too much thyroid hormone can cause a hyperthyroidism crisis that can even be fatal, so don’t be clever!
Thyroxine can promote physical and intellectual development, the most obvious effect is in infants and young children, it mainly promotes the growth and development of bones, brain and genitals. If thyroid hormone is lacking in infants and young children, it will cause infants and young children to have retarded growth and development and mental retardation, which will cause “staying sickness”. I guess some people will wonder: “Does increasing thyroid hormone make children taller and smarter?” The answer is still no! Too much thyroid hormone will not have this effect, but will have the side effects mentioned above. Therefore, we only need to ensure that there is no lack of thyroxine during childhood.
Thyroxine also has the effect of increasing central nervous excitement. Normal doses can keep people alive, and deficiencies can lead to mental exhaustion and disinterest in anything.
If there are 5 or more of the following symptoms, it may be hyperthyroidism (commonly known as hyperthyroidism), please seek medical treatment in time:
1. Easy to get excited;
2. Irritability and insomnia;
3.Palpitation and rapid heartbeat;
4. Afraid of heat and sweat;
5. Increased appetite, but weight loss or weight loss;
6. Increased stool frequency or diarrhea;
7. Female menstruation is rare;
9. Eyes protrude outward.
If you have 5 or more of the following symptoms, you may be suffering from hypothyroidism (commonly known as hypothyroidism), please seek medical treatment in time:
1. Feeling weak, lacking energy and energy, and slowing down the reaction;
2. Slow thinking, difficulty concentrating, memory loss;
3. Reduced appetite but gain weight;
4. Dry skin and brittle nails;
5. Be afraid of cold;
6. Depression and depression;
8.Heartbeat becomes slow;
9. Elevated blood lipids.
In short, more and less thyroid hormones will have an impact on human health. It is recommended that thyroid hormone secretion be monitored regularly, especially in patients with previous thyroid diseases. Maintaining normal thyroid hormone secretion can make the body healthier.
