Thyroid
Sex Organs
Functions of Hormones
1.) Help Regulate:
‐ Metabolism and energy balance
‐ Biological clock (circadium rhythm)
‐ Glandular secretions
‐ Some immune activities
Functions of Hormones (cont.)
2.) Control growth and development
3.) Govern reproduction

•Controls rate at which bodyproduces energy
•Controls body temperature
Thyroid
y p
•Affects mood
•Impacts immunity
Adrenal Glands
The Adrenals
Four basic hormonal functions:•Glucocorticoids regulate blood sugar and inflammation
An important part of the “fight or flight” h imechanism
•Mineralocorticoids regulate mineral balance, particularly sodium and potassium
•DHEA production – our ‘anti‐aging hormone’Production of sex hormones

FUNCTIONS OF CORTISOL
•Literally can’t live without it•Mobilizes and increases amino acids•Boosts energy levelsI di ti•Improves digestion
•Eases joint movement•Lessens inflammation and pain•Enhances immune function•Maintains personality and emotional stability
FUNCTIONS OF DHEA
•Increases muscle mass; decreases body fat•Improves cardiovascular function
•Enhances immune systemEnhances immune system
•Helps prevent decreased mental function
•Helps fat loss; increases lean body mass
•Stimulates new bone growth
• Ovaries produce the female sex hormones: estrogens and progesterone in cycling
Sex Organs
women.
• Testes produce the primary male sex hormone, testosterone.

DIS‐EASE OR DYSFUNCTION
Stressors
• Poor Diet• Mental/Emotional/• Physical• Biochemical
DIETARY STRESSORS
•Poor nutrient intake = bad fuel
•S.A.D. can lead to gut issues
•Caffeine/alcohol overuse
•High carb = glycemic/adrenal issues
•Food allergies/intolerances
•Insufficient protein can createneurotransmitter deficiencies

MENTAL STRESSORS
•Work overload • Late hoursSl d i i•Sleep deprivation
•Financial worries• Unfulfilling life •Negative thoughts
MENTAL STRESSORS
EMOTIONAL STRESSORS
Death of loved one DivorceJob Loss AngergUnfulfilling relationships GuiltFearfulness LonelinessNot feeling heard Not having fun

PHYSICAL STRESSORS
•Trauma or illness•Lack of exercise•Excessive physical exertionp y•Whiplash and Subluxations•Surgery•Chronic pain•Lack of relaxation
BIOCHEMICAL STRESSORS
Liver overload AllergiesDysbiosis MoldsI f ti I fl tiInfection InflammationXenobiotics EMFsAnemia Malabsorption
SYMPTOMS OF ADRENAL DYSFUNCTION
•Hypoglycemia•Cravings for sweets•Moments of confusion/Poor memory•Premenstrual tension•Weight control problems•Food and/or inhalant allergies•Poor resistance to infections

Chief Complaints of Adrenal Insufficiency
•Excessive fatigue•Nervousness/Irritability•Mental Depressionp•Inability to concentrate•Apprehension•Light‐headedness•Insomnia

ADRENAL/THYROID CONNECTION
Low thyroid function is usually secondary to
adrenal stress!
