THYROID DISEASE IS KILLING US

More than 30,000,000 people in the US and 200 million worldwide have a Thyroid Disorder Most affected are women. Some estimates are over 50 million in US and over 200 million worldwide, and growing.

Estimates vary widely as most patients are misdiagnosed or undiagnosed because doctors don't know what they are looking for.

Thyroid disease is also an autoimmune disease. This means that over 27 million people have one or more of the over 105 known autoimmune diseases.

Thyroid Health – The Affects of Iron on Your Thyroid, T4 and T3

Iron…why do we need iron?

Because, when we’re iron deficient we can become anemic, causing tiredness, fatigue, weakness, dizziness, irritability, shortness of breath or depression. Other signs may include pale skin, brittle nails, chest pain, cold hands or feet or an irregular heartbeat. Less common symptoms of anemia include pica, an urge to eat ice and other nonfood items. Low iron may also cause sexual dysfunction and problems concentrating on mental tasks.

Boy, sounds like all the symptoms of hypothyroidism!

Check with your practitioner and get a lab test to check your iron if you have these symptoms, but most of them may just be your thyroid.  Don’t assume that just an over the counter iron tablet is the answer.

Iron, in addition to iodine, selenium and zinc,

are essential for normal thyroid hormone metabolism.

 

LOW IRON LEVELS CAN AFFECT T4 AND T3

low iron levels decreases deiodinase activity, i.e. it slows down the conversion of T4 to T3. Biologically, insufficient iron levels may be affecting the first two of three steps of thyroid hormone synthesis by reducing the activity of the enzyme “thyroid peroxidase”, which is dependent on iron.

Thyroid peroxidaxe brings about the chemical reactions of adding iodine to tyrosine (amino acid), which then produces T4 and T3. Insufficient iron levels alter and reduces the conversion of T4 to T3, besides binding T3. Additionally, low iron levels can increase circulating concentrations of TSH (thyroid stimulating hormone).

 

IRON AND PRODUCTION OF CORTISOL

Even worse, good iron levels are needed in the production of cortisol via the adrenal cortex. An iron-containing protein is present in high amounts in the adrenal cortex and is involved in the synthesis of corticosterone. So by having low iron, you can potentially lower your cortisol levels.

    i have my graduation project about the effect of iron in thyroid gland
    the result come back with:
    low dose of iron 800 micron/day show significant increase in T3 & T4
    but show significant decrease on TSH

    high dose of iron 8000 micron /day show no significant in all parameter

    my study was held on male albino rats 200-250 gm for 2 months

    no i want explanation or mechanism of low dose to my thesis

      Hi Ahmed,
      I am not a medical practitioner, but I am a great researcher! I’ll have to refer you to your local medical field or online search. Sorry! Good luck and I’m so glad that you’re studying this!

      Hi Javier,

      Your thyroid health is more in-depth than just kelp!

      Your doctor will only be able to help you in small ways if they are not a thyroid trained practitioner – to do the right lab tests and then read them correctly – to see what all is happening in your body to prescribe the right plan for you, which includes diet and supplements to rebuild your thyroid health. Go to my site page and find one in your area ASAP for a 2nd opinion if your doctor is not doing these things for you right away. http://thyroidu.com/practitioners/ He or she may tell you to start thyroid medication, but this is only a fraction of the answer.

      You’ll need a thyroid healing diet as well. You can get this in my manual and get a jumpstart on your work with your thyroid trained practitioner – see here: http://thyroidu.com/bookstoreresources/my-thyroid-health-plan-manual/
