Thyroid problems affect over 25 million Americans, half of whom are not even aware they have this medical issue, studies confirm. Most of thyroid disorders, 90% to be more specific, are hypothyroidism or under-active thyroid.

This butterfly-shaped gland is located bilaterally at the base of the neck. Taken that numerous processes in the body depend on this gland, it’s no wonder the thyroid is one of the most important parts of the human body. When thyroid function is affected, so is your entire health.

These are the 10 warning signs of an under-active thyroid:

  1. Emotional tantrums, anxiety or depression.
  2. Mental issues, including brain fog, inability to focus and poor memory.
  3. Weight gain and inability to lose weight.
  4. Hormone imbalances: PMS, sporadic periods, infertility and low sex drive.
  5. Muscle agony, joint torment, carpal tunnel disorder or tendonitis.
  6. Neck swelling, snoring or dry voice.
  7. Dry and peeling skin, fragile nails and unreasonable male pattern baldness.
  8. Exhaustion after 8 to 10 hours sleep at night or need to take a nap during the day.
  9. Cold hands and feet, or having a body temperature lower than 37 degrees Celsius.
  10. Clogging.

What’s the thyroid gland function?

The secretion of thyroid hormones largely depends on three factors – the hypothalamus, the pituitary and the thyroid gland. The hypothalamic thyrotropin – discharging hormone (TRH) enables pituitary thyrotropin (TSH) production, which in turn creates grounds for the secretion of T4 and T3, both hormones produced by the thyroid. When enough T4 is secreted, TRH and TSH receive signals that there is sufficient thyroid hormone available for use. It’s this signal that stops further production of T4.

As found by studies, T4, which is an idle type of hormone, accounts for nearly 85% of the hormone secreted by the thyroid. After T4 is released, some of it transforms into T3 – the dynamic type of thyroid hormone.
