Module 2 Flashcards
What is the biggest factor driving the release of aldosterone?
The renin angiotensin system (fluid, potassium, sodium)
List 3 ways to increase the body’s removal of estrogen?
a. Increased intake of fibre and fat combined together
b. Balance gut bacteria (reduce SIBO)
c. Decrease exogenous estrogens
d. Reduce alcohol consumption
e. Reduce Cortisol
`. Are high levels of aldosterone or low levels more detrimental to the body?
Decreased aldosterone levels can lead to altered cardiac function
What is the primary effect of cortisol on blood sugars?
Increases blood sugar levels (resistance)
What effect does chronic elevation of cortisol do the balance between aerobic and
anaerobic systems?
Drives toward anaerobic
What neurotransmitter does NOT undergo homotropic modulation?
Acetyl Choline
What effect does decreased T3 have on neurotransmitter function?
Reduced ability of the post-synaptic neuron to propagate an action potential due to
a decrease in the release of synaptic vesicles from the presynaptic bouton
Does cortisol inhibit insulin secretion?
a. No.
b. Long term elevation of cortisol decreases insulin receptor sensitivity
c. Cortisone directly inhibits insulin secretion
List three peripheral consequences for gluconeogenesis with respect to amino acids?
a. Loss of muscle tissue/mass
b. Loss of tendon structure/integrity
c. Loss of neuronal integrity and precursor amino acids for NT production
How does increased estrogen effect CRH levels?
Actively drives CRH production due to increased hypothalamic transcription
List two things that will affect the function of GABA?
a. Cortisol levels driving carbohydrate dysregulation
b. Hypothyroidism – reduced GAD 65 function
c. GAD autoimmunity (normally gluten derived)
d. Decreased levels of biotin which afffects GABA binding (gut dysfunction drives decreased biotin availability)
List three consequences of increased SHBG?
a. Increased estrogen / decreased testosterone
b. Estrogen based heterotropic modulation
c. Testosterone based heterotropic modulation
What is the best way to measure cortisol levels in the body?
Cortisol salivary
What is pregnenolone steal and when would you expect to see this in a patient’s history?
a. Pregnenolone steal is where upregulated cortisol production utilises the vast
majority of pregnenolone which results in a decreased ability of the body to produce
other steroid hormones (DHEA and sex hormones)
b. The patient’s history would have a history of chronic HPA dysfunction and long term
associated symptoms of this
If an OPK tape was run from the patients left to their right what muscle pattern weakness
would you expect to see if there was a HPA problem?
a. Left PMS inhibition
b. Right quadriceps and lats
