Thyroid Functions in our Body and its importance

Last updated on January 21st, 2023 at 12:12 pm

Thyroid functions include the production, release, and uptake of thyroid hormones. These hormones regulate a wide variety of physiological processes, such as basal metabolic rate, body temperature, and appetite.

Thyroid hormones are produced in the thyroid gland and regulate metabolism – including the way your body uses energy. The thyroid gland is at the base of your neck, just under your Adam’s apple.

Thyroid Functions in our Body

Thyroid Functions – The thyroid gland, or simply the thyroid, is an endocrine gland in the neck, comprising two lobes connected by an isthmus. It is found at the front of the neck, below Adam’s apple. The thyroid gland secretes thyroid hormones, which primarily influence the metabolic rate and protein synthesis. The hormones also have many other effects, including those on development. The thyroid hormones triiodothyronine (T3) and thyroxin (T4) are created from iodine and tyrosine. The thyroid also produces the hormone calcitonin, which plays a role in calcium homeostasis. The hormonal output from the thyroid is regulated by thyroid-stimulating hormone (TSH) secreted from the anterior pituitary gland, which itself is regulated by thyrotropin-releasing hormone (TRH) produced by the hypothalamus.

What are the symptoms of an under-active thyroid?

  1. Fatigue after sleeping 8 to 10 hours a night or needing to take a nap daily.
  2. Weight gain or the inability to lose weight.
  3. Mood issues such as mood swings, anxiety, or depression.
  4. Hormone imbalances such as PMS, irregular periods, infertility, and low sex drive.
  5. Muscle pain, joint pain, carpal tunnel syndrome, or tendonitis.
  6. Cold hands and feet, feeling cold when others are not, or having a body temperature consistently below 98.5.
  7. Dry or cracking skin, brittle nails, and excessive hair loss.
  8. Constipation.
  9. Mind issues such as brain fog, poor concentration or poor memory.
  10. Neck swelling, snoring, or hoarse voice.

How does the thyroid gland work?

Thyroid hormone production is regulated by a feedback loop between the hypothalamus, pituitary gland, and the thyroid gland. Hypothalamic thyrotropin-releasing hormone (TRH) stimulates pituitary thyrotropin (TSH) synthesis and secretion.

TSH stimulates the production and release of T4 and T3 from the thyroid gland. When enough T4 is produced, it signals to TRH and TSH that there is enough thyroid hormone in circulation and not to produce more.

About 85% of the hormone produced by our thyroid gland are T4, which is an inactive form of the hormone. After T4 is made, a small amount of it is converted into T3, which is the active form of thyroid hormone.

To complicate matters, T3 also gets converted into either Free T3 (FT3) or Reverse T3 (RT3). It’s the Free T3 that really matters in all of this since it’s the only hormone that can attach to a receptor and cause your metabolism to rise, keep you warm, keep your bowels moving, mind working, and other hormones in check. The role of Reverse T3 is not well known. However, I see it elevated in people under extreme stress and those who have mercury toxicity.

And finally, Hashimoto’s thyroiditis, an autoimmune disease, is the most common form of hypothyroidism and its numbers are rising annually. An autoimmune disease is one in which your body turns on itself and attacks a certain organ or tissue, believing its foreign.

I routinely screen all of my patients for autoimmune thyroid disease by ordering Thyroid Peroxidase Antibodies (TPOAb) and Thyroglobulin Antibodies (TgAb).

  6. Thyroglobulin Antibodies (TgAb)

What are 10 things you can do to improve your thyroid function?

The thyroid gland produces hormones that regulate the body’s metabolism, which controls how quickly your body uses energy, makes proteins, and controls how sensitive the body’s organs are to other hormones.

10 Effective tips to improve thyroid functions
  1. Make sure you are taking a high-quality multivitamin with iodine, zinc, selenium, vitamin D, and B vitamins.
  2. Go gluten-free! If you have Hashimoto’s, try going completely grain and legume-free.

  5. Have a biological dentist safely remove any amalgam fillings you may have.
