Aldosterone release is stim. by this:
Low blood Na lvl.
Aldosterone release is stim. by this:
High blood K lvls.
Aldosterone release is stim. by this:
Lower BP (d/t loss of blood or dehydration) (Low BP activates RAA in the kids l/t Angiotensin II l/t increased secretion of aldosterone.).
Aldosterone release is stim. by this:
Aldosterone non-release: When BP rises the atria secretes ANP. That inhibits the rel. of aldosterone (renin) l/t the kids elim. Na l/t water following the Na, l/t BP going down.
This can be Primary or Secondary:
<Cortisol/Hydrocortisone, <Aldosterone, & 'Addison's Disease'.
re: Hyposecretion. This is an example of Primary:
ACTH from the Pit is elevated (in an attempt to stim. the Adrenal Cortex to synthesize more hormones).
This is an example of Secondary:
Deficient ACTH fails to stim. Adrenal steroid synthesis.
The following are s/s of < Cortisol/Hydrocortisone, < Aldosterone, Addison's Disease:
Sodium & water loss, < BP, hypotension, > HR (the response), the Pt craving Na.
If the Pt craves Na it could be a s/s of this:
< Cortisol/Hydrocortisone, < Aldosterone, Addison's Disease
S/s of < Cortisol/Hydrocortisone are similar to this:
S/s of <Aldosterone & Addison's Disease
This is how the body responds to <Cortisol/Aldosterone:
< BP then it > HR
This is a Mineralocorticoid that causes the kidneys to retain Na:
Aldosterone
This happens if there is no Aldosterone:
Na leaves & water leaves as well.
This stims the metabolism/breakdown of carbs:
Cortisol
Low Cortisol l/t this:
Hypoglycemia & lower blood sugar
Hypoglycemia & lower blood sugar l/t this:
Weakness, fatigue, wt. loss, confusion, psychosis, anorexia, n/v (which l/t electrolyte imbalances).
