Hi that was a really helpful video.
Just a quick question; if I used a high dose dex test and cortisol levels was still high; instead of it being a tumour in the lungs causing an increase in ACTH, could it instead be an adrenal adenoma releasing excess cortisol; I'm assuming dex would not stop the adrenal glands from producing excess cortisol if they were the issue?
Thanks
you are right… high dose dex test dont supress the production of the cortizol by adrenal adenoma
Incredible 😮
Thank you so so much!!
thank you

Is fasting recommended for dogs prior to the low dose dexamethasone test? My vet had us withhold all food for 24 hours. Her test came back negative, but I am afraid it was skewed from the extra long fasting.
I am so sorry!!! You gotta ask a vet...
Probably late to the party. My cardiologist did blood test (I have POTS with orthostatic high blood pressure) and also a blood test of my hormones. Test results came back (I will have my cardiologist visit in 3 weeks) and my ACTH and cortisol are both over maximum limit. Can this might be Cushings?
I only heard of POTS this past year (a woman with MG was misdiagnosed with panic disorder when she moved during a procedure!) I can't diagnose online - try to ask an endocrinologist!
I also have POTS (along with lupus) and am awaiting the results of this test.
Why doesn’t the high amount of cortisol in body suppress ACTH release in first place?
Negative feedback
High ACTH caused higher than normal cortisol which by negative feedback suppressed further more increase in cortisol. Dexamethasone administration now have negative feedback which makes the reduction from high cortisol noted before the test
What if a patient does shift work (11-7) or goes to sleep between 4 and 6AM? Can this interrupt the normal release of these hormones?
Hey Jen, my guess is that it makes no difference because cortisol will be suppressed either way, but I would ask an endocrinologist. Please let me know if you find out!
@@AJmonics I am here because my Endo doesn't know. I was referred to him because of low acth, dhea, and tumor on the adrenal. Last year he only did a baseline and 8mg suppression tests. Said everything is good. He said he'll do 8mg suppression test every year (no baseline) for 4 years to see if the tumor is active. This year, I questioned him about my sleep cycle and he said he'd research it.
From you wonderful presenters on CZcams, I've learned that I need acth and cortisol done and 1mg, then 8mg if necessary, correct?
I am sorry that must be a lot for you... correct 1mg of dex; then 8 mg if necessary.
@@AJmonics Thank you!
Is dexamethasone suppression test used these days?
Yes! Sorry for the delayed response..
When would you take the 1 mg before you get your blood drawn
Hello Qiana! You take 1 mg the night before (around 11pm), and your blood is drawn the next morning at around 8am. Please let me know if you need anything else! Good to hear from you!
@@AJmonics my lab work is for 9am so do I take it at 12
You can take it between 11 and 12.
Either one is fine!
@Qiana Tarver how did the test go Cushing ,mild Cushing or you're good ???
The background music is so distracting 😢
Totally agree - I made a mistake with my old videos
What does it mean if cortisol is very low after this test? Like under 1.20 is that normal?
Great question Jennifer. I believe anything lower than 1.8 micrograms in the morning is considered low.
My guess is that you are not in medical school. =) Medical students don't know values like that.
Let me know if you need anything else Jennifer!
❤
Very satisfied
Thank you!!!
