The Hypothyoird Connection to Weight Regulation

Thursday, May 03, 2012

The thyroid gland which is located right below your larynx normally produces a hormone called thyroxine. This hormone controls the body's metabolism as I have explained on many occasions, but just to refresh:

"Metabolism is the set of chemical reactions that happen in the cells of living organisms to sustain life. These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environments. The word metabolism can also refer to all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells."

Thyroxine is more known as T4 where as triiodothyronineis known as T3. Both which work in sync in the body.

* T3 is needed for fat loss
* T3 protects against arrythmias
* T3 decreases with stress or dieting
* T3 is active hormoneT4 is prohormone
* T4 does not necessarily convert to adequate T3

Hypothyroid is becoming more common: with only 10% diagnoses in 1920 and now anywhere from 70%-80% today.(subject to bias and many other factors of coarse)

When the thyroid gland begins to produce less thyroxine the functions of the body begin to slow down and many health complications ensue. People may experience anything from fatigue and sluggishness to hair loss and boner loss. Why is it that many practitioner's feel it's more accurate to make the diagnoses on clinical grounds?

Most of the thyroid hormone circulating in the blood is bound to transport proteins. Only a small portion of the thyroid hormone is free(unbound) and active, thus measuring free thyroid hormone in the blood is of great value.

Measuring the total amount can be misleading since not all of thyroid hormone is unbound as stated above.

The thyroid hormones act on nearly every cell in the body through membrane transport. They work to increase the basal metabolic rate, affect protein synthesis, Regulate long bone growth, and increase sensitivity to Catecholamines (such as adrenaline).

    Yikes, yea these posts are more for people with sluggish thyroid not necessarily having it removed. (I'm not qualified to handle anything of that magnitude). I wonder is people who have had their thyroid removed would fair better with dessicated thyroid instead of synthetic? Guess it's case dependent.

    Had Hashimoto's, thyroid removed 2008. Have slowly gained 30 pounds over that time. A recent synthroid adjustment gives me hope that I may be able to reverse this horrible trend. Thanks on behalf of myself and all others who do not understand why they are experiencing these horrible symptoms.
