5 Functions of the Thyroxine Hormone in the Body

Windowofworld.com – The thyroxine hormone is one of the important hormones in the human body. Its main function is to regulate the body’s metabolism. Therefore, the level and function of the hormone thyroxine needs to be maintained to remain normal, so that the body’s metabolism can run well.

The thyroxine hormone or T4 is one of two types of thyroid hormone produced by the thyroid gland in the neck. Another type of thyroid hormone is triiodotironin or T3. The production of T4 and T3 hormones is regulated by thyroid stimulating hormone (TSH which is produced by the brain).

These hormones play an important role in regulating the functions of various organs of the body and maintaining our overall body health.

Various Functions of Thyroxine Hormone

The thyroxine hormone is actually a non-active form of thyroid hormone. When needed by cells and body tissues, the thyroxine hormone will be converted into its active form, the T3 hormone. This T3 hormone works directly on the cells and tissues of the body.

This thyroxine hormone in the active form will later work to regulate various functions of the body’s organs and ensure the body remains healthy. The following are some functions of the thyroxine hormone in the body:

1. Regulate the body’s metabolism

Metabolism is the process of forming energy and the natural heat of the body by all cells and tissues of the body. If the metabolic problem, then automatically the performance of the body’s organs will also be disrupted.

Therefore, metabolism needs to be regulated so that it can take place stable. This thyroxine hormone plays a role in regulating how fast or slow metabolism progresses.

2. Maintaining the function and work of the heart

The heart works endlessly to pump blood that carries nutrients and oxygen throughout the body. Sometimes the body’s organs or tissues need more blood flow. To regulate this process, the thyroxine hormone works by strengthening the heart pump so that blood flow is sufficient.

3. Maintain brain function

The thyroxine hormone also functions to ensure the brain stays awake, alert, and sensitive to surrounding conditions and stimuli received by the body. When the thyroxine and T3 hormones are reduced, the body will become more sleepy and difficult to concentrate.

4. Maintaining the function of reproductive organs

The thyroxine hormone has an important role in regulating the performance of the reproductive organs in men and women.

Thanks to the thyroxine hormone, a woman’s body can ovulate and menstruate regularly every month. Whereas in men, the thyroxine hormone plays a role in stimulating the hormone that regulates the process of sperm formation.

5. Stimulate growth hormone production

The thyroxine hormone plays an important role in the growth of the fetal brain in the womb and ensures the growth and development of the baby runs smoothly after birth.

In children, the thyroxine hormone also works to help the formation of growth hormone. Thanks to this hormone the child’s body size and weight can increase and they can experience puberty.

Deficiency and Strength of the Thyroxine Hormone

Too little or too much thyroxine in the body can cause health problems. The following are various effects that can be experienced by the body if the deficiency or excess of the thyroxine hormone:

Excess thyroxine hormone

The condition when the body has too much thyroxine in the blood is called thyrotoxicosis. The signs are as follows:

  • Goitre or swelling in the neck due to enlarged thyroid gland.
  • Irregular menstrual cycles.
  • Reduced weight.
  • Not resistant to temperature or hot weather.
  • Fatigue.
  • Emotions and moods change quickly, for example being anxious and more irritable.
  • The heart beats faster.
  • Indigestion, such as more frequent bowel movements or stomach discomfort.
  • Excessive sweating.
  • Trembling hands.

Thyrotoxicosis can occur due to several conditions, namely thyroiditis or inflammation of the thyroid gland, hyperthyroidism, Graves’ disease, use of thyroid hormone stimulating drugs.

Thyroxine hormone deficiency

The body can also produce too little the thyroxine hormone. This condition is known as hypothyroidism. Some of the symptoms are:

Hypothyroidism can be caused by several conditions or diseases, such as Hashimoto’s disease, congenital hypothyroidism, surgical removal of part or all of the thyroid, radiation therapy to the thyroid gland, iodine hormone deficiency, and side effects of drugs, such as drugs to reduce thyroid hormone.

If you feel symptoms that indicate a disruption in the amount of thyroid hormone, this condition should be checked by a doctor.

To diagnose disorders of the thyroid hormone and thyroxine hormone, the doctor will conduct several examinations, such as blood tests, thyroid ultrasound, to scanning tests on the thyroid gland that utilizes radioactive iodine.

After the doctor finds the cause and diagnosis, treatment will be given so that your thyroxine hormone returns to normal.

Steps to Maintain the Function of the Thyroxine Hormone

The following are some steps you can take to maintain a healthy thyroid gland:

  • Eat nutritiously balanced foods, such as fruits, vegetables, milk and processed products, and seafood.
  • Reducing foods that contain bad fats and simple carbohydrates, such as sugar, fast food, and processed foods.
  • Avoid consumption of offal, such as the intestine, tripe, or animal spleen.
  • Eating enough iodized salt, which is no more than 2 grams per day.
  • Do not smoke.
  • Exercise regularly.

In addition to the above steps, regular health checks to the doctor regularly are also important steps taken to maintain the health of the thyroid gland.
