Thyroxine hormone effects

Thyroxine hormone. over-secretion and under-secretion of thyroxine hormones.

Ever looked at most basketball players and asked, Are these humans or they are simply imported from another world?

Those tall guys you see or watch playing basketball are affected by the secretion of the Thyroxine hormone.

Thyroxine, also known as T4, is a hormone produced by the thyroid gland. It is a major regulator of metabolism, growth, and development. Thyroxine is made up of four iodine atoms and two amino acids. It is released into the bloodstream and travels to all parts of the body.

Thyroxine works by binding to receptors on cells. When it binds to a receptor, it activates a series of reactions that lead to increased metabolism. This includes increased production of heat, energy, and protein. Thyroxine also plays a role in the development of the brain and nervous system.

The production of thyroxine is controlled by the thyroid-stimulating hormone (TSH) from the pituitary gland. When TSH levels are high, the thyroid gland produces more thyroxine. When TSH levels are low, the thyroid gland produces less thyroxine.

Too much or too little thyroxine can cause health problems. Hyperthyroidism is a condition where the thyroid gland produces too much thyroxine. This can cause symptoms such as weight loss, anxiety, and heat intolerance. Hypothyroidism is a condition where the thyroid gland produces too little thyroxine. This can cause symptoms such as weight gain, fatigue, and cold intolerance.

Thyroxine can be replaced with medication if the thyroid gland is not producing enough of it. This medication is usually taken as a pill. Thyroxine replacement therapy is usually safe and effective. However, it is important to take the medication as prescribed and to have regular blood tests to monitor levels.

Here are some of the functions of thyroxine hormone:

  • Regulates metabolism: Thyroxine helps to regulate the body’s metabolism, which is the process of converting food into energy.
  • Promotes growth and development: Thyroxine hormone is essential for growth and development, especially in children and adolescents.
  • Regulates body temperature: Thyroxine helps to regulate body temperature.
  • Controls heart rate and blood pressure: Thyroxine helps to control heart rate and blood pressure.
  • Maintains bone health: Thyroxine helps to maintain bone health by promoting the formation of new bone and preventing the breakdown of old bone.
  • Regulates the nervous system: Thyroxine helps to regulate the nervous system by promoting the development and function of nerve cells.

If you have any concerns about your thyroid health, talk to your doctor. They can do a blood test to check your thyroxine levels and recommend treatment

First, for the records, what are Thyroxine hormone?

Thyroxine hormones are a type of hormone secreted by the thyroid gland and they help regulate the rate of metabolism and also stimulate physical growth in young animals and humans.

Now that is Thyroxine hormones, but what if the body malfunctions and over-secretion takes place or there is a secretion, What are the possible effects?
Effects of over-secretion of Thyroxine hormone
Thyroxine hormone can be said to be over-secreted if the following conditions are observed in the body
1. The over secretion of Thyroxine hormone causes hyperthyroidism which is a condition of increase in metabolism rate. This is the increase in the way the body system carries out internal activities in order to release energy.
2. Over activities or hyperactivity is a definite effect of over-secretion of Thyroxine hormone.
3. Excess secretion of the Thyroxine hormone leads to excessive growth beyond the normal.
4. It also leads to loss of weight in animals
5. Over secretion of Thyroxine hormones can cause exothermic goitre also as enlarged thyroid gland
6. It causes high rate of heartbeat
7. Enlarged eyeballs are an effect of over over-secretion of Thyroxine hormones
So having looked at the effect of over-secretion of Thyroxine hormones, let’s take a look at the effects of under-secretion of Thyroxine àlso.
Effects of under-secretion of Thyroxine hormones in the body
1. One major sign of under-secretion of Thyroxine hormones is that it leads to hypothyroidism which is a condition of decrease in the metabolism rate of the body. This state of low Thyroxine hormone production in the body is also known as myxoedema
2.  An under-secretion of Thyroxine can lead to mental and physical sluggishness
3. Whenever Thyroxine hormones are secreted and are under-secreted, it ultimately leads to dwarfism or cretinism in infants (children)
4. One of the major causes of obesity or overweight is the under-secretion of Thyroxine.
5. It causes a low heartbeat rate
6. Under secretion of Thyroxine hormones can lead to the formation of goitre, a type known as hyperplastic goitre.
The over-secretion and under-secretion of Thyroxine hormones play a very important role in the development of the body system of animals. When you notice any of those listed conditions in an animal, then you are faced with hormone imbalance which is the result of malfunctioning of the Thyroid gland.
