All that you need to know about Thyroid Gland

Written by Dana Peterson

1) What is thyroid gland

The thyroid gland is a glandular portion of the immune system that generates the hormones that are needed to maintain a healthy human body. This organ secretes the hormones thyroxine (often abbreviated TSH) and thyroid stimulating hormone (TSH).

Also, this organ works on producing the thyroid-stimulating hormone (TSH), which serves as an emergency signal to the pituitary gland that shuts off the thyroid.

Mainly, the thyroid secretes the hormone thyroxine, which travels through the blood stream throughout the body, to the target tissues where it aids in the growth and repair of cells and protein, particularly of the muscle strength.

This vital organ also secretes and produces the hormone thyrotropin. The thyroid controls and regulates the body temperature by regulating the variation in core body temperature and circulating hormonal imbalance.

As the thyroid aids in these functions, it also increases the heart rate, increases the body’s muscle strength and regulates the brain and other organ functions. It is thus vitally important for the health of a human being.

2) How does the thyroid gland work?

the doctor shows the patient a brochure about the thyroid gland and its functions.

The thyroid gland is an important part of your endocrine system. It is mainly made up of small glands that produce, store, and secrete hormones into your bloodstream so that the hormones will reach the different cells of your body.

The hypothalamus makes TSH, a type of thyroid hormone, that triggers the pituitary gland in your brain to trigger the thyroid to produce more T4 and TSH.

These two hormones are used to help control your metabolism and help maintain your normal daily function.
One should note that, Iodine is required for the normal functioning of your thyroid gland. When you do not get enough iodine, your thyroid will produce too little hormone.

In other words, HYP iodine is an underlying factor of many thyroid diseases like goiter, anemia, chronic fatigue and chronic pain. So, make sure you get enough iodine in your diet.

On the other hand, the thyroid gland is an extremely important small organ, which is located in front of the sternum, just behind the Adams apple (thyroid cartilage).

It is shaped roughly like a butterfly with two large wings which extend around your back and down the left side of your neck. The thyroid gland is actually a gland made up of a single cell which produces and releases thyroid hormones which regulate metabolism and growth.

These hormones also regulate the metabolism of other cells such as muscle, fat and other tissues. If you have a malfunction in these hormones, it can lead to serious health conditions, including hypothyroidism. The thyroid also produces and secretes high levels of calcium, which is necessary for bone mass.

3) Common thyroid diseases

1- Hypothyroidism

The symptoms of hypothyroidism are many, but they generally involve weight gain, depression, hair loss, dry skin and brittle nails. As the thyroid hormones start to go wrong, the body cannot produce enough of the thyroid hormones, leading to hypometabolic state and other disorders.

For example, the most common type of thyroiditis is Hashimoto’s thyroiditis, which is caused by an imbalance in the thyroid hormone called TSH or thyroid stimulating hormone.

This leads to the overproduction of thyroid hormones. There are many causes of Hashimoto’s thyroiditis including radioactive iodine, diabetes, medication, food allergies, and an underactive thymus. Nodules (including moles) can also be a symptom.

This condition is caused by an underactive thyroid or a disorder of the thyroid gland that can be caused by an accident or disease. Some doctors believe that hyperthyroidism may also be caused by radiation therapy, especially after cancer surgery.

Hyperthyroid patients may feel restless and cold like many times a day and may be prone to constipation. The symptoms of this disorder include sweating, restlessness, and jaundice.

People suffering from hypothyroidism may have problems such as constipation, fatigue and hypoglycemia. They are also prone to weight gain, muscle weakness, palpitations, sleep disorders and depression. Many people suffering from hypothyroidism take thyroid hormones but they find it difficult to tolerate the synthetic hormone.

2- Clinical depression

Clinical depression can be a factor if the patient suffers from hyperthyroidism or nodules of the thyroid gland. In this condition, the patient will have high levels of cortisol, which is produced because the body needs energy.

People with this type of depression may show signs of insomnia, fatigue, and anger. They can also go through mood swings and severe episodes of panic attacks. A person with hyperthyroidism or nodules of the thyroid should seek medical attention.

3- Autoimmune disorder

Autoimmune disorder can also be a root cause for hypothyroidism. An autoimmune disorder is a disorder of our bodies’ immune system. This system starts to attack the healthy cells or tissues causing damage and leading to illnesses. Systemic Lupus erythematosus, septic arthritis and reactive arthritis are some autoimmune disorders that can lead to hypothyroidism.

4- Peeding-induced hyperthyroidism

Peeding-induced hyperthyroidism is caused by the body trying to use up too much thyroid hormone by way of an overactive thyroid. When the thyroid gland makes too much thyroid hormone, it stimulates the pituitary gland to release iodine.

Iodine is needed for many normal body functions including thyroid gland production. This condition called hyperthyroidism can cause fatigue, hair loss, slow pulse, dry skin, muscle weakness, constipation, and fast heart rate. Feeding induced hyperthyroidism can even cause hearing loss.

Hypothyroidism can affect people who have a thyroid gland problem but are unaware of it because the symptoms do not fit any typical description. Butterfly-shaped bend in the neck can occur due to a subacute thyroid problem or acute.

A subacute thyroid problem can be life threatening because it involves damage to the brain, lungs, or liver. Acute hypothyroidism affects the thyroid gland directly, producing very few symptoms, and thus very few medical tests are required to diagnose it.

In case you or a loved suspect that you are dealing with such symptoms, a visit to your primary care physician becomes necessary in order to start the treatment as soon as possible and avoid serious complications.
