Treating and Beating Low Thyroid
Your Thyroid Gland� The thyroid gland is shaped like a butterfly
and is located in the lower front part of your neck (just above the breastbone).
� It’s responsible for secreting thyroid hormones, which travel through the bloodstream and help cells convert oxygen and calories to energy.
� Basically, thyroid hormones control a person’s metabolism.
Metabolism � Metabolism is defined as the sum of all physical and
chemical changes that take place within the body.
� If your thyroid is compromised, every cell and organ is affected.

Thyroid Disorders�According to the American Association of Clinical
Endocrinologists over 27 million Americans suffer from thyroid dysfunction, half of which go undiagnosed.
�Over 500,000 new cases of thyroid disease occurs each year.
www.TreatingandBeating.com
Hypothyroidism� Over 10 million women with thyroid dysfunction go
untreated.
� Another 8 million have “true” or classic hypothyroid and go undiagnosed.
� Hypothyroidism affects women 5-7 times more than men.
Thyroid Disorders� Hypothyroidism is a condition in which the thyroid
gland does not make enough thyroid hormone-underactive or low
� Hyperthyroidism or Graves Disease, is a condition in which the thyroid gland makes too much thyroid hormone. The condition is often referred to as an "overactive thyroid."

Thyroid Hormones�The thyroid produces hormones that influence every
organ, tissue, and cell in the body.
�Thyroid hormones also control heart rate, body weight, body temperature, energy level, muscle strength and and menstrual regularity.
�Your thyroid controls cellular energy (metabolism), maintains body temperature, regulates proper cell and tissue growth, affects brain function, moods and emotions.
Symptoms of Hypo(low)Thyroid
� fatigue (the most profound symptom)
�headache
�dry skin
� swelling
�weight gain
�cold hands and feet
4/4/2014

Symptoms of Hypo(low)Thyroid
�poor memory
�hair loss
�hoarseness
�nervousness
�depression
Symptoms of Hypo(low)Thyroid
�joint and muscle pain
�burning or tingling in the hands and/or feet
�yellowing of skin from a build up of carotene (conversion of carotene to vitamin A is slowed by hypothyroidism)
�carpal tunnel syndrome
Symptoms of Hypo(low)Thyroid
� problems with balance and equilibrium
� constipation
� myxedema (non pitting edema due
to the deposition of mucin in the skin), especially around the ankles and below the eyes
4/4/2014
5
Symptoms of Hypo(low)Thyroid
�high blood pressure
�chest pain
�hardening of the arteries
�high cholesterol
�menstrual irregularities, PMS, and infertility
Symptoms of Hypo(low)Thyroid
� fibrocystic breast disease
� polycystic ovary syndrome
� reactive low blood sugars
�Psoriasis
�nasal allergies-sinus infections
Thyroid Hormones
�Hormones are internal secretions transported through the bloodstream to various organs.
�The thyroids main purpose is to produce, store, and release two important hormones-
� triiodothyronine (T3) and thyroxine (T4).
4/4/2014
6
Thyroid Releasing Hormone
�TRH causes the pituitary gland to secrete thyroid stimulating hormone (TSH).
�TSH goes up when the body needs more thyroid hormones and down when the body needs less thyroid hormones.
Thyroid Hormone Feedback Loop� The pituitary gland produces thyroid stimulating
hormone (TSH).
� TSH then triggers the thyroid gland to produce thyroid hormones.
� Once the brain brain senses the thyroid gland has released enough hormones, TSH will be decreased.
TSH� Through this negative feedback system TSH and
thyroid hormone production is controlled.
� The higher the TSH number the less thyroid hormones in the circulatory system (blood).
� The lower the TSH number the more thyroid hormones in the circulatory system (blood).
4/4/2014
7
TSH� When TSH is elevated (high) in a blood lab test
Above 4.5 on conventional lab tests
Above 3.0 on functional medicine lab tests
This is interpreted by doctors as Hypothyroid or low thyroid (TSH going up to trigger release of more thyroid hormones)
TSH� When TSH is deficient (low) in a blood lab test
Below .04 on conventional lab tests
Below 1.0 on functional lab tests
� This is interpreted by doctors as Hyperthyroid or overactive thyroid (TSH going down to trigger release of less thyroid hormones)
Thyroid Peroxidase (TPO)
�The release of TSH triggers thyroid peroxidase enzymes (TPO) to combine iodine with hydrogen peroxide creating T3 and T4 hormones.
�Anything that disrupts TPO enzyme function, interferes with proper thyroid hormone production and lowers thyroid function!
4/4/2014
8
T3 and T4�T3 hormone is a combination of the amino acid L-
tyrosine and three iodine molecules.
�T4 hormone is a combination of L-tyrosine and four iodine molecules.
T3 and T4�Eighty percent of thyroid hormones are T4 hormones
and seven percent are T3 hormones.
�T3 is considered the active hormone. It is 300 times stronger or more active than T4 and the hormone responsible for increasing metabolism.
T3 and T4� Twenty percent of T4 becomes active in the intestines,
provided there is enough “good bacteria” available(probiotics).
� Eighty percent of T3 comes from the conversion of T4 into the more active T3
� Most of the conversion of T4 into T3 conversion takes place in the liver.
4/4/2014
9
T3 and T4 Hormones�T3 and T4 are carried through the blood stream by
protein molecules known as thyroxine binding globulin (TBG).
�TBG carries the thyroid hormones to the appropriate cells.
�Anything that interferes with TBG will compromise thyroid function.
Stress and Nutritional Deficiencies
� The thyroid gland—which is controlled by the hypothalamus and pituitary—may become compromised by any disruption to the HPA axis.
� So stress definitely takes a toll on thyroid function. Short-term stress causes an elevation of cortisol, which then blocks the conversion of T4 to active T3.
� Long-term stress can also compromise thyroid function
Stress Compromises Thyroid Function� The thyroid gland—which is controlled by the
hypothalamus and pituitary, and linked with the adrenal glands (HPA axis)—may become compromised by any disruption to the HPA axis.
� So stress definitely takes a toll on thyroid function.
4/4/2014
10
Hypothalamus Regulation
� Your hypothalamus gland constantly monitors all the systems in your body.
� This master gland acts as your body’s regulatory computer, monitoring then making adjustments as needed.
� The hypothalamus produces thyroid- releasing hormone (TRH).
www.TreatingandBeating.com
Adrenal Fatigue� Acute or chronic long-term stress may compromise the
adrenals leading to a condition known as adrenal fatigue syndrome.
� Many of the symptoms of adrenal fatigue, fatigue, low moods, cold hands and feet, headaches, “brain fog,” low body temperature, etc., mimic those of low thyroid.
G.A.S� General Adaption Syndrome
3 Phases
� 1. Fight or Flight Response is the initial alarm reaction. Pituitary releases adrenocorticotrophic hormone (ACTH)
� Adrenaline and cortisol are released from the adrenal glands.
� Short-term stress causes an elevation of cortisol, which then blocks the conversion of T4 to T3.
4/4/2014
11
Resistance Stage � Cortisol is the main player in this phase of GAS. The
resistance reaction allows the body to endure chronic stress.
� However long term stress comes at a price.
Adrenal Exhaustion� Chronic over secretion of cortisol leads to adrenal
exhaustion, which accelerates the downward spiral towards chronic poor health.
� Once in adrenal exhaustion your body can’t release enough cortisol to keep up with the daily demands. Eventually you become deficient in cortisol
Adrenal Fatigue� Clues you may have adrenal fatigue:
� Crave salt
� Skip breakfast
� Low blood sugar
� Low blood pressure
� Cold hands/cold feet
� Less tolerant of stress
4/4/2014
12
Adrenal Fatigue� The best way to test for adrenal fatigue is to work with
your functional doctor and have them order a four sample adrenal cortisol/DHEA panel done.
� Another option is to self test by taking your blood pressure lying down, then again within 30 seconds of standing. Your systolic number should go up by 10 points, if not then you most likely have adrenal fatigue.
Adrenal Glandular Supplements� Adrenal cortical glandular extracts
� Typically use 500mg twice a day breakfast and lunch.
� Here is the adrenal supplement I use for my patients
� http://store.drmurphreestore.com/adrenal-cortex-500501.html
� Don’t recommend using whole glandular supplements only adrenal cortex
� Read more about adrenal fatigue http://drrodgermurphree.com/adrenal-fatigue/
Stress and Nutritional Deficiencies
� Long-term stress -depletes the nutrients needed to keep thyroid hormones at peak levels. Nutrition is involved in every aspect of T4 production, utilization, and conversion to T3.
� The minerals zinc and iodine; vitamins A, B2, B3, B6 and C; and the amino acid tyrosine are all needed for the production of T4.
4/4/2014
13
Nutritional Deficiencies� A deficiency in just about any of the B vitamins will
contribute to low thyroid function.
� Low levels of copper, magnesium and manganese may also prevent optimal thyroid function.
Stress and Nutritional Deficiencies
� Selenium is needed to convert T4 to T3, so a deficiency in this mineral can also cause thyroid dysfunction.
� High blood levels of fatty acids can also inhibit conversion of T4 to T3.
� A deficiency in iodine or the amino acid tyrosine especially can lead to thyroid dysfunction.
Iodine Deficiency
� Iodine is simply necessary to generate thyroid hormones (T4 has four atoms of iodine, and T3 has three).
� While many experts suggest that iodine deficiencies are rare in this country, our consumption has dropped drastically over the last 20 years.
4/4/2014
14
Iodine Deficiency
� One test for iodine deficiency is the skin-patch test.
� Using a 2% Lugol’s solution (available at any drug store), paint a 2-inch square patch onto your abdomen.
� Iodine deficiency is indicated if the painted patch disappears within 24 hours. If it lasts longer than 24 hours, your iodine status is normal.
Iodine Self Testing
� If you test low in iodine, add one of any number of kelp or iodine supplements to your diet.
� Hashimoto’s Thyroiditis may become worse with iodine therapy (check for thyroid antibodies).
Prescription Medications and Low Thyroid
� Antidepressant medications alter the HPA axis by making the thyroid-releasing hormone(TRH) and thyroid-stimulating hormone (TSH) pathway less efficient.
� Antidepressants also divert the amino acid L-tyrosine, the precursor for the neurotransmitters dopamine and norepinephrine, from converting into the thyroid hormone T4.
� This is a bit ironic, since low thyroid function is a major cause of depression.
4/4/2014
15
Prescription Medications and Low Thyroid
� Interferon typically interferes with thyroid function, and secondary thyroiditis occurs in up to 14% of those taking interferon.
� Methadone, synthetic estrogen, Tamoxifen, and cholesterol-lowering drugs increase the binding of thyroid hormones to chemicals that inactivate thyroid hormones.
� Dilantin (Phenytoin) and Carbamazeprine(Tegretol) decrease T4 and T3 by about 20%.
Leads to Low Thyroid Function� Certain Foods: Some foods eaten to excess may
contribute to goiters and alter thyroid function: broccoli, cauliflower, Brussels sprouts, cabbage, mustard, kale, turnips, canola oil, soy, pine nuts, millet, and peanuts.
Hashimoto’s Thyroiditis
Chronic thyroiditis is a swelling (inflammation) of the thyroid gland that often results in reduced thyroid function (hypothyroidism).
4/4/2014
16
Over-Stimulated Immunity
� Hashimoto’s thyroiditis is a type of autoimmune thyroid disease in which the immune system attacks and destroys the thyroid gland.
� Hashimoto’s thyroiditis is the most common form of hypothyroidism and is generally treated with thyroid hormone replacement therapy.
Hashimoto’s Thyroiditis
� In most cases of Hashimoto’s thyroiditis there is a steady slow, gradual attack against the thyroid tissue leading to a decline of optimal thyroid function.
� In Graves disease the attack is against the thyroid cells-leading to hyperfunction.
� Most people who have Hashimoto’s never actually develop over active thyroid disease.
Hashimoto’s Thyroiditis� Treating the symptom, elevated TSH, instead of the
autoimmune disease leaves patients vulnerable to ongoing health issues and risk for further thyroid decline.
� Patients often go on meds yet never feel any better. The key is to treat the trigger or cause of the autoimmune attack-the trigger that is causing the attack of thyroid tissue.
4/4/2014
17
Hashimoto Thyroiditis
� Symptoms include those normally seen in hypothyroid disease, including fatigue, depression, sensitivity to cold, weight gain, muscle weakness, coarsening of the skin, dry or brittle hair, constipation, muscle cramps, increased menstrual flow, and goiter (enlargement of the thyroid gland).
Hashimoto’s Thyroiditis
� Polycystic ovary disease syndrome (PCOS)-has been identified as a trigger for causing autoimmune thyroiditis.
� PCOS is the most common female hormone disorder in the United States. It typically presents as the inability to lose weight, infertility, hair loss, fatigue after meals, hormone dysfunctions, and sugar cravings. Insulin resistance is the driving factor.
PCOS
� A blood test will reveal elevated fasting glucose, triglycerides, testosterone, and cholesterol.
� Triglyceride levels above the total cholesterol is strongly suggestive of insulin resistance.
� Insulin resistance is a condition in which the cells of the body become resistant to the hormone insulin.
4/4/2014
18
PCOS
Insulin resistance increases the activity of the enzyme 17,20 lyase, found in the theca cells of the ovaries, which leads to increased production of both testosterone and estrogen.
Over-Stimulated Immunity
� Low progesterone in women age 30–50 may lead to Hashimoto’s disease as elevated estrogen levels cause the immune system to become over-stimulated.
� To compound this potential problem, estrogen-like chemical compounds can also block thyroid function. By binding to the estrogen-receptor sites on cells, they cause an increase in circulating estrogen.
Over-Stimulated Immunity
�These chemicals include common environmental pollutants such as PCBs (polychlorinated biphenyls), dioxins, and pesticides. Unfortunately, though no longer produced in the US, these chemicals are routinely found in our food and water supply.

What Else Can Go Wrong with the Thyroid Gland?
� An imbalance in the estrogen-progesterone ratio can also
interfere with proper thyroid function. So a vicious cycle may
ensue when low thyroid function (from chronic stress) alters
the normal estrogen-progesterone balance, which then
contributes to further low thyroid. This case may be especially
true for autoimmune thyroid disease.
� About 75% of autoimmune diseases occur in women, most
frequently during their childbearing years.
Hashimoto’s Triggers
� Low vitamin D levels-Vitamin D-optimal 50 ng/ml
� Gluten intolerance or full blown Celiac disease-
� Elevated estrogen
� Iodine is the major cofactor and stimulator for thyroid
peroxidase (TPO). TPO is the enzyme under attack in
Hashimoto’s. Iodine supplements can make condition
worse.
� Infectious agents
Viral Triggers
�Rubella-German measles
�Rubeolla-measles
�Retrovirus-RNA Virus
� Influenza B
�Coxsackie
�Yersina-bacteria in the enterobacter family
�EBV
� I use XFLM to treat Hashimoto’s:http://store.drmurphreestore.com/thyroid1.html

20
Thyroid Antibodies
� Elevated thyroid antibodies indicate the body’s immune system is attacking and compromising the thyroid gland. Thyroid antibodies may trigger hypo or hyper thyroid function.
Thyroid Antibodies
� Thyroid Peroxidase antibody (TPO)
� This is the most common elevated antibody.
� Thyroglobulin antibodies (TgAb) isn’t nearly as common as TPO but should be ordered on initial blood work.
� Thyroid stimulating Hormone Receptor Antibody (TRAb) is ordered only when hyperthyroid is suspected-TSI
The first antibody, anti-TPO, attacks an enzyme normally found in your thyroid gland, called the Thyroid Peroxidase, which is important in the
production of thyroid hormones.
The second antibody, TgAb, attacks the key protein in the thyroid gland, the thyroglobulin, which is essential in the production of the T4 and T3 thyroid hormones.

There are three types of hypothyroid:
primary, secondary, and tertiary.
� Primary hypothyroidism arises from a deficiency in the thyroid gland.
� Secondary hypothyroidism involves the pituitary gland.
� In tertiary hypothyroidism, the hypothalamus gland shuts down in response to overwhelming stress.
Hypothyroid Protocols
� There are a variety of different causes or triggers for low thyroid function. In the next several slides I outline the various protocols.
The majority of this information comes from my 5th edition book, Treating and Beating Fibromyalgia and Chronic Fatigue Syndrome
www.getfibrobooks.com
www.TreatingandBeating.com
Primary Hypothyroidism
�True dysfunction of thyroid gland
�TSH will be elevated above 3.0 on blood test
�Free and Total T4 usually normal or low
�Free T3 normal or low
�T3 uptake normal
�RT3 is normal
4/4/2014
22
Protocol
� Thyroid glandular supplement or RX
� Priority One Thyroid 300 one BID on empty stomach
Re-check labs in 6 weeks
� Good optimal daily allowance multivitamin
� Don’t recommend thyroid glandular with iodine and or L-tyrosine.
� Iodine can aggravate autoimmune thyroiditis and tyrosine can suppress TPO function.
Pituitary Hypofunction Protocol
� Thyroid glandular 300
� Pituitary glandular
� Good optimal daily allowance multivitamin
� Patient will often have low blood sugar issues
� Adrenal cortisol panel and adrenal fatigue protocol recommended
Under Conversion
� Chronic adrenal stress leads to excess cortisol
� Excess cortisol will block T4 from converting into active T3 hormone
� Infections and free radical damage can interfere with cellular absorption
� Since low T3 doesn’t affect blood levels of TSH these patients often get missed
4/4/2014
23
Under conversion
� Free T4 and Free T3 will be low
� All other markers will be normal
www.TreatingandBeating.com
Thyroid Resistance
� Brought on by stress. Pituitary and thyroid producing adequate hormones but hormones aren’t entering cells.
� All thyroid labs are normal.
� Adrenal Fatigue is the usual culprit here.
� Test for and treat adrenal fatigue using appropriate protocols.
Autoimmune Thyroid
� Elevated TPO and or TBG = autoimmune attack and thyroid gland destruction
� Thyroid Peroxidase and Thyroglobulin antibody
� When either or of these antibodies shows up on a blood test-first look for trigger, look for and treat cause, second use appropriate nutritional protocols to reduce the antibody.
� Use XFLM to treat http://store.drmurphreestore.com/thyroid1.html

TH-1 and TH-2 and Cytokines
�TH-1 dominance
�TH-1 is the initial response to a foreign invader or antigen. T-Helper cells are up regulated and release cytokines, cellular protein messengers.
�TH-1 release inflammatory cytokines IL-2 and TNF-a
TH-2
�TH-2 is a delayed reaction where cells release anti-inflammatory cytokines IL-4, IL-5, IL,10, and IL-13.
Blood Test for TH-1 or TH-2
� TH-1/TH-2 Panel
� TH-1 dominant
elevated IFN and or IL-2 will be elevated
� TH-2 dominant
� IL-4 and or IL-10 will be elevated
4/4/2014
25
TH-1 TH-2 Challenge90% of cases are TH-1
TH-2 dominance best treated with:AstragalusEchinaceaGlycyrrhizinLemon BalmMaitake mushroom
Mycoceutics is what I use http://store.drmurphreestore.com/thyroid1.html
TH-1
�TH-1 dominance best treated with:
Pine bark extract-pycnogenol
Grape seed extract
Green tea extract
Resveratrol
XFLM is what I use with my patients http://store.drmurphreestore.com/thyroid1.html
Challenging
� Use one or more of the stimulating products for either TH-1 or TH-2.
� Challenge one at a time. If symptoms become worse then suspect need the one not challenging.
� Ex-if challenging with TH-1 stimulants and have negative reaction then switch to TH-2 stimulant supplements
4/4/2014
26
Antioxidant Mix
� I normally start an antioxidant anti-inflammatory supplement with with then if no problems redo blood tests in one month to see if the TPO and or TGB are going down. If they aren’t going down I’ll challenge with opposite formula and retest again in one month.
� To learn more about this formula go to www.treatingandbeating.com store
Hashimoto’s Thyroiditis
� May not see an elevated TSH
� Blood work may still look normal
� WHY? Because doctors are not doing a comprehensive panel
� We want to catch them before they go through years of misery.
� Do the detective work!
Review Triggers
� PCOS
� Elevated testosterone & estrogen levels
� Low vitamin D
� Gluten intolerance
� Insulin resistance
� Autoimmune, ie: Epstein Barr Virus
4/4/2014
27
Elevated TSH
� OTC Glandular T3 (Priority One thyroid 300 one BID)
� Thyroid 300 http://store.drmurphreestore.com/thyroid1.html
� Most doctors don’t treat people with a level of 3.5 or even 4.0, but in the Functional Medicine world, anything above 3.0, they need to be treated.
www.TreatingandBeating.com
TSH is Above 3.0 & Everything Else is
Normal.
� Put them on a good Optimal Daily vitamin and Priority 300 one BID� http://store.drmurphreestore.com/thyroid1.html
� Make sure their adrenal function is optimal – adrenal test kit or test them with an orthostatic blood pressure test.
� Most will need an adrenal protocol.� http://store.drmurphreestore.com/adrenal-boosters.html
� Re-check at 6 weeks. Adjust OTC supplements that you recommended as needed.
Elevated Reverse T3
� Place them on OTC Thyroid 300
� Re-check in 4 weeks, make sure it’s decreasing.� Thyroid 300 is what I use
http://store.drmurphreestore.com/thyroid1.html
If patient is on a synthetic medication, ie, Synthroid, that can cause an elevated Reverse T3 because the synthetic T4 is NOT converting into active T3.
� Encourage them to get their doctor to write them a Rx for Armour Thyroid instead or use Thyroid 300
4/4/2014
28
OTC Glandulars Alter Blood Work
Tell them to discontinue the OTC medication at least 3-4 weeks before they go back to their doctor, because their blood work will be altered. The medical doctor will assume he needs to reduce their hormone replacement medication, which will then compromise their treatment.
Dr. Broda Barnes was the first to show that a low basal body temperature was associated with low thyroid. His first study was published in 1942 and appeared in The Journal of the American Medical Association.
This study tracked 1,000 college students and showed that monitoring body temperature for thyroid function was a valid if not superior approach to other thyroid tests.
Self Test for Low Thyroid
A reading at or below 97.8 strongly suggests hypothyroid. A reading above 98.2 may indicate hyperthyroidism (over active thyroid).
If using a digital thermometer wait 2 hours after waking up and take under the tongue (don’t eat, drink or brush your teeth 10 minutes before taking temperature).
4/4/2014
29
Thyroid 300� Put them on OTC Thyroid 300
� http://store.drmurphreestore.com/thyroid1.html
� Re-test in 4 weeks
� Continue to monitor their body temperature
� Will NOT always see the body temperature go up (Like in Wilson’s protocol)
� Goal is to change the subjective symptoms and continue to monitor their blood work.
Keep It Simple.
� Always address adrenal fatigue.
� Always check if TSH is above 3.0
� Check under/over conversions
� Elevated Reverse T3 can be due to Stress
� Low body temp with Low thyroid symptoms – Treat them for Euthyroid.
Using these Protocols
� You can help 85-90% of people that come to your practice
� For 10%-15% who are not responding, take the Apex course, and you will definitely benefit, as I have.

4/4/2014
35
Reverse T3 (RT3)
� When your body needs to conserve energy, it may convert 50% or more to RT3, and the T3 is compromised.
