Hi This is the first time I actually understood Addison's Disease in which I've had for 14 years. It was absolutely fantastic. Easy for non medical people to understand, explained clearly and thoroughly and even repeating things so we didn't miss anything. Thank you very much. Wish I had of found this earlier.

[@Medcram]

Thanks so much for the feedback. Glad the video was helpful!

[@Medcram]

As a point of note, the ovaries do secrete some androgens, but the adrenal converts most of it into a usable form.

[@maria-pazcoe1475]

Very good. Thank you

[@Medcram]

No Problem... ACTH is a tropic to the adrenal gland so even though potassium stimulates the zona glomulosa, too much ACTH will cause it to make more aldosterone. Additionally, high quanities of cortisol with cross-react with aldosterone receptors since they are both steriod molecules. This is what gives you the aldosterone effects of high ACTH.

[@manjitdhami]

I am so sorry, but you described Z glomerulosa (aldosterone secretion) not affected by ACTH levels and then when describing Cushing's disease (not syndrome) you say high ACTH will cause low K+, H+, high Na - signs of high Aldosterone secretion. How is that possible?

[@normulyani6416]

ACTH is necessary for aldosterone secretion but has little effect in controlling the rate of secretion.

[@shiwanisharma3746]

It's really useful for us sir thank u

Are you referring to Cushing's Disease (and not Addison's)?

[@albertonatividad8665]

Thank you very much!

[@aliassadi7164]

just i have one qus, for cushing syndrome there is no influence on zg just on zf and zr, so i think the aldosterone level will be normal since it stimulated by high K not by acth. thanks for all the effort

Hi and thanks for a very informative video! I wonder about Cortisol. If you suffer from adrenal fatigue after having had Graves disease, and thereby major anxiety (at its worst in the morning and best at night) and fatigue, is cortisol the friend or foe? And how does one recover from this? Only thing I know of is to ingest adrenal gland powder, in swedish binjureextrakt. (Not sure about the translation but a powder or pill that contains extract from animal adrenal gland.) Do you know how long it takes to recover from adrenal fatigue?

[@Donna777]

+Vixinaful - I'm sorry you have not received an answer to your question after all this time. I don't have an answer either (I also have AF), but I would like to share an AMAZING Facebook group with you called "Adrenal Fatigue Recovery". I just joined the other day and all I can say is WOW WOW WOW!!! The information within that group is astounding! I have been reading nearly non-stop for the past two days; I can't seem to pull myself away from it! I have never seen so many people who share the same problems I have...to a T. If you join the group I guarantee you will find the answers you seek. The people there are awesome! Very knowledgeable and ready to help with advice or just a listening, supportive ear. It's so nice to be in a place where people "get it" and totally understand me. It's the best group I've ever belonged to, feels like one big supportive family. Hope to see you there! :)

[@Vixinaful]

***** Thank you soo so much. I'll check it out straight away! :)

[@jasonkwok4095]

addisons is adrenal insufficieny = less aldosterone = less K+ and H+ secreted = more H+ in blood = metabolic acidosis

[@sujiewansuj3788]

what

[@positivevibes7425]

You have said in the video that aldostetone is not regulated by ACTH so why levels of aldostetone are increasing in Cushing syndrome or Cushing disease since they happen because of administration of pharmacologic doses of CORTISOL or production of high levels of ACTH by pituitary gland.

[@basimali2733]

Hi Dr Seheult. Great video. Just wanted to point that at 7:38 you say that the only source of androgen in females in the adrenal cortex. That's not true. Up to 25% of testosterone is normally synthesized by the ovaries in females. Thanks again.

I found out when i was 16 my mom was devistated but i knew everything would be ok. I have to take medicine every day for the rest of my life it sucks but having a sore chest is natural thankfully all is well just that i look like a child even though im 18 hehe but thankfully god blessed me in a time where there is medicine for my condition

[@Matt-re4et]

I don't think z. Glomerulosa relies soley on positive or negative feedback stimulus, doesn't ACTH play a role?

In Chinese medicine and meditation, this is referred to as the second gate or the Chia Chi. It is one of the major gates in the Microcosmic Orbit and its significance is confirmed by Western Medicine as it impacts so many physiological functions.

Thank you so much! But is it only K+ which controls aldosterone secretion? What about Angiotensin ll?

[@لاإلهالاالله-و6ح]

When Blood pressure decrease or hypokalimia that stimuli Renin_ angiotensin system in kidney to secret Renin that convert to angiotensin 2 to affect adrinal cortex and produce aldosterone

Hello and thank you. I have had a brain tumor removed, most of it. I can't stay awake much. I was looking around and was wondering if what could cause the tumor is the lack of cortex or the Adrenal Gland itself not feeding me enough cortex. Also is there anyway to work on the Adrenal Gland and help it out.. Thank you

Thanks for the video.Can I ask why PCOS wasn't mentioned when dysfunction with the glands was covered?

[@rdseheult]

sound like primary adrenal failure (addison's disease). this could make you tan as well. Should get that checked out soon.

[@chrishaywood9821]

So what if a person has one adrenal gland, and the other had been taken away with a partial nephrectomy?

[@MissAgentPerry]

I am surprised that the RAAS system was not even mentioned when you talked about what stimulates aldosterone release!!

[@swalls48]

i have addison disease so this is obviously very interesting to me. thank you for making this available to the public.

[@fraros04]

In cushings disease, I understand that glucose and testosterone levels rise due to increased ACTH but why would aldosterone be oversecreted as well if after some time potassium levels would be low?? wouldn't low potassium levels stop the secretion of aldosterone??

You said for women, their only source of androgens are from the renal cortex? I believe ovaries also make some testosterone in the theca cells.

[@josphellihsilak4588]

Nice, presentation but in Addison disease there is metabolic alkalosis not acidosis!!

In addisons disease metabolic acidosis occurs, as H+ secretion decrease

It causes metabolic acidosis with normal anion gap, and it is called as Renal Tubular Acidosis type 4
