Assumptions In The Interest Of Time
• You Know the Basics of the Endocrine System
• This is Based on Literature and Experience
• Physicians have Preconceptions
• Linear vs Systems Thought Processes
• Modern Medicine is Disease Focused
• Dogma vs Truth and the Shades Between
• This is NOT a Comprehensive Discussion
• 2 hr lecture in 45 minutes
• A Few Busy Slides
• You Have My Bio

activation
Understand the link between the Adrenal, Thyroid,
and Pancreas (A-T-P)
Review how Stress, Metabolism, and Sugar are
linked in the approach of patient energy and vitality
Discuss a biology systems approach in assessing
future health risk (MetS, Sleep, CVD)
Review issues with focused organ treatment
If Time: Bring in a Little Nutrition
Adrenal-Thyroid-Pancreas Connection
• What will be missing:
• In depth detailed marker/hormone structure
discussion
• Detailed Testing Discussion
• Treatment of A-T-P connection imbalances
Adrenal-Thyroid-Pancreas Connection
• A-T-P Connection is a Systems of Vitality and
Energy
• When it’s GOOD
• Energy is great, stress in balance, you have a
general feeling of well being
• When it’s BAD
• Fatigued, weight gain, sluggish
• This is a fluid model of systems
• NOT Linear!
Adrenal-Thyroid-Pancreas Connection
• Our Systems act together in an Elegant Dance

Adrenal-Thyroid-Pancreas Connection
• EXERCISE as an example
• Moderate vs Intense
• Moderate: Improves mood, sugar metabolism,
oxygenation of tissues, increases enzymatic fat
burning activity
• Intense: Increased cortisol, dysglycemia, amino
acid deficits, immune stress, create catabolic
metabolism, and proneness to injury
Clinical Effects of Excessive HPA axis Activation
OUTCOMES?

Clinical Effects of Excessive HPA axis Activation
• OUTCOMES?
• Stress Response AHHHHHHHH!!!!!
• Sarcopenia, osteopenia, sydrome X, immunological
compromise, cognitive decline, frailty, CVD, etc.
• Chronic Stress
• Increased Allostatic Load
Hormones and Neurotransmitters
Adrenal
Thyroid
Pancreas
Adrenal Glands
Adrenal Glands Produce over 50 Hormones:
Cortisol and Aldosterone most abundant
ADRENAL CORTEX
ADRENAL MEDULA
Zona Glomerulosa: Aldosterone
Epi: 80%
Zona Fasiculata: Cortisol
Zona Reticularis: Androgens,
pregnenolone, progesterone
Norepi: 20%
CORTISOL
• The “Stress Hormone”
• Regulated by hypothalamis-pituitary-adrenal
(HPA) axis
• Cortisol levels follow a circadian rhythm in
metabolic homeostasis
Thank You Dr. James LaValle
Chronic CORTISOL Elevation
•Increased insulin secretion
•Increased fat deposition
•Alteration in immune function
•Muscle wasting
•Hypothyroidism (adrenal exhaustion)
•Memory loss
•Alteration in sex hormones
•Loss of REM, mental and emotional instability
•Increased blood lipids, plaque formation, CVD
•Receptor site activation of tumor cells
Thank You Dr. James LaValle
Normal Diurnal Hormonal Level

•ACTH and Cortisol levels positively associated with inc.
systolic and diastolic BP, triglycerides, fasting glucose, and
insulin resistance
•Cortisol (Not ACTH) positively associated with increased LDLcholesterol

associated with cardiovascular risk factors

•112 adults
•295.3ng/g active MI cases
•224.9ng/g control
•Controlling for all AMI factors Hair Cortisol was the
strongest predictor of AMI
~~Gotta Ask: How many
Cardiologists measure cortisol?
1.) Pereg et al., Stress: Vol.14 Issue 1 p. 73-81 January 2011
CORTISOL and Sleep
• Sleep and Cortisol Release
• Controlled in slow-wave sleep
•
By decreases in corticotropin-releasing hormone (CRH)
and increases in GH
• Increase Stress
•
•
•
•
•
1.)
HPA-axis dysfunction, disruption of diurnal patter of
GH, CRH, ACTH release
Results in a paradoxical rise of nocturnal cortisol levels
Sleep phase dysfunction
Nocturnal hypercortisolism
Feeds into itself increasing cortisol even more
CORTISOL and Exercise
• Hyper/intense exercise without counter-
measures drives up cytokine/inflammatory,
metabolic “dysbalance”
• People don’t appreciate the term “moderate
exercise”
1.)
CORTISOL
• Prime Target in Approach to Healing metabolic
Homeostasis?...
• The Circadian Rhythm
• Elevated serum Cortisol produces an overall
net acid effect
• Blood pH homeostasis actually become
detrimental to overall physiology
• Mg and Ca pool is depleted to help buffer blood pH
Chrousos, G. P. Organization and integration of the endocrine system: the sleep and wakefulness
perspective. Sleep Med. Clin. 2, 125–145 (2007)
Adrenal-Thyroid-Pancreas Connection
• Adrenal Glands and Chronic Stress:
• Elevated Cortisol:
• DHEA Levels Decrease
•
•
Now Focused on Stress
Sex Drive drops-changes making testosterone, Progesterone, etc.
• Seratonin Levels Decrease
•
Depression, anxiety, cravings for sugar/carbs, “flat” feeling
• Melatonin Levels Decrease
Melatonin and Insulin Regulation
Melatonin influences insulin secretion via the Gprotein-coupled at MT1 and MT2 receptors
•Interferes with insulin secretion from beta cells and
transmitting circadian timing information to the islets
•Circadian insulin secretion is adapted to day/night
changes via melatonin-dependent synchronization
Melatonin regulates blood sugar and circadian
insulin secretion
THUS: SLEEP IS OFF, BLOOD SUGAR DISRUPTED,
DIABETICS

Metab. 2010;24(5):829-41.
Adrenal-Thyroid-Pancreas Connection
• Adrenal – Thyroid Connection Closely Linked
• Both under hypothalamic control/tropic hormones
• Thyroid competes with adrenals for tyrosine
• Chronic stress……increased cortisol….dec thyroid
• Not enough tyrosin for T3/T4 production
• Under stress body unable to convert from
phenylalanine

Saunders Elsevier; 2015
Adrenal-Thyroid-Pancreas Connection
• Adrenal – Thyroid Connection
• Increased Cortisol Output
•

•
•
1.)
Inhibits 5’deiodinase limiting T3 production from T4
TRH unregulated to form more T4
Alters metabolism of fats, sugars, and proteins
Adrenal-Thyroid-Pancreas Connection

•
1.)
rT3 Binds to T3 receptors
Blocks T3 from binding!
Exercise Intensity and Thyroid Function
• 2005 Clinical Study
• n=60 male well trained athletes
• Compared thyroid hormone levels at 45%, 70% and
90% of max HR
• TSH, T4 and fT4 levels increased at 70 and 90% vs.
45%
• fT3 and T3 increased at 70%, but fell at 90%
• Thought to be due to elevations in cortisol

How Insulin Receptor Should Work
Thyroid-Pancreas and PGC-1 α
•T3 regulates PGC-1α (1)
•PGC-1α co-activates the thyroid receptor
• PGC-1α stimulates hepatic gluconeogenesis and
fatty acid oxidative metabolism(2)
• PGC-1α increases the expression of GLUT 4 in
skeletal muscle.
•Increases glucose uptake in cells
~PGC-1α expression reduced in obesity/DM-T2/IR(3)

• Practical Usefulness of Markers

• Dominance of Each Organ System
• Bone Disease, Cancer Risk, Obesity, etc.

Quick Clinical Pearls
• Think ACTUAL Underlying Issue
• Think Diurnal Cortisol Disruption
• Look Up-Stream
• If treating a system and Tx is not working?
• “Adrenal Fatigue?” Not so much
• HPA-axis no longer signals adrenals
• Centrally Mediated Effect
• L-Carnitine 2-4 grams a day regulates T3 and T4 entry
into the cell helping to modulate hyperthyroid state
