What is the Thyroid Test? A Test for Thyroid Disorder

A thyroid disorder occurs when there is too little thyroid hormone or too much thyroid hormone. How do I know if my thyroid is healthy? Find out what your thyroid test results mean!

Thyroid Test

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 the thyroid problem?

  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 your 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 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 is 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, we 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).

What is the blood test for thyroid disorder?

You can check the below panel on each of your family with the above symptoms. Make sure your doctor refer the same for you. You can also book your own thyroid lab tests to evaluate your thyroid function. Common search for thyroid test, thyroid test in Pune, thyroid lab test, thyroid test near me ultimately ends here.

How to improve thyroid function?

A thyroid disorder occurs when there is too little thyroid hormone or too much thyroid hormone. Symptoms include feeling tired, having trouble sleeping, being unable to lose weight, and having difficulty concentrating.

10 things you can do to improve your thyroid function

  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.
  3. Deal with your stress and support your adrenal glands. The adrenal glands and thyroid work for hand in hand. We recommend restorative yoga and adaptogenic herbs such as this blend of Pure Encapsulations, which support the adrenal glands in coping with stress.
  4. Get 8 to 10 hours of sleep a night.
  5. Have a biological dentist safely remove any amalgam fillings you may have.
  6. Watch your intake of raw goitrogens. There is a bit of a debate surrounding this.
  7. Get fluoride, bromide, and chlorine out of your diet and environment.
  8. Heal your gut. A properly functioning digestive system (gut) is critical to good health.
  9. Find a functional medicine doctor in your area and have them run the above laboratory test and work with you to find your root cause of the thyroid imbalance.
