It's estimated that as
many as 25 million Americans have a thyroid problem, and half of them have no
idea that they do. Hypothyroidism,
or an under-active thyroid, accounts for 90% of all thyroid imbalances.
The thyroid, a butterfly-shaped gland in the center of your neck, is the master gland of metabolism. How well your thyroid is functioning is inter-related with every system in your body. If your thyroid is not running optimally, then neither are you.
Here are 10 signs that you could have an underactive 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 you 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.
In turn, 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, I do see it elevated in persons 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 begins to attack a certain organ or
tissue believing its foreign.
Why is hypothyroidism
so under diagnosed?
Many symptoms of
thyroid imbalance are vague and most doctors spend only a few minutes talking
with patients to sort out the cause of their complaint.
Most conventional
doctors use only one or two tests (TSH and T4) to screen for problems. They are
not checking FT3, RT3 or thyroid antibodies.
Most conventional
doctors use the ‘normal’ lab reference range as their guide only. Rather than
listening to their patients symptoms, they use ‘optimal’ lab values and
temperature as their guide.
Which lab tests are
best to determine if you have a thyroid problem?
Make sure your doctor
does the below panel of tests for you.
- TSH
- Free
T4
- Free
T3
- Reverse
T3
- Thyroid
Peroxidase Antibodies (TPOAb)
- Thyroglobulin
Antibodies (TgAb)
What are the ‘optimal’
lab values for thyroid tests?
The below are the
ranges in which patients thrive
- TSH 1-2 UIU/ML or lower (Armour or compounded T3 can artificially suppress TSH)
- FT4 >1.1 NG/DL
- FT3 > 3.2 PG/ML
- RT3 less than a 10:1 ratio
RT3:FT3
- TPO – <9 IU/ML or
negative
- TgAb - < 4 IU/ML or
negative
What are 10 things you
can do to improve your thyroid function?
1. Make sure you are taking a high quality multivitamin with Iodine, Zinc, Selenium, Iron, Vitamin D and B vitamins.
2. Take a tyrosine and iodine supplement to help with the FT4 to FT3 conversion.
3. Go gluten-free! If you have Hashimoto’s, try going completely grain and legume free.
4. Deal with your stress and support your adrenal glands. The adrenal glands and thyroid work hand and hand. I recommend restorative yoga and adaptogenic herbs, which support the adrenal glands in coping with stress.
5. Get 8 to 10 hours of sleep a night.
6. Have a biological dentist safely remove any amalgam fillings you may have.
7. Watch your intake of cruciferous vegetables.
8. Get fluoride, bromide and chlorine out of your diet and environment.
9. Heal your gut. A properly functioning digestive system (gut) is critical to good health. This can be done by using the following 4 R approach i.e. remove, replace, reinoculate, and repair -
10. Find a functional medicine doctor in your area and have them run the above laboratory test and work with you to find our root cause of the thyroid imbalance.
