- WHAT IS ALDOSTERONE?
Aldosterone is a hormone released by the adrenal glands (ontop of the kidneys).
And it plays a HUGE role in balancing fluids and electrolytes inside the body.
In this video, we'll answer the question, what is aldosterone?? As well as dive into what you need to know about aldosterone for your med surg nursing classes, especially for your fluids and electrolytes modules!
Here's a quick summary of aldosterone function:
1. Aldosterone is released if the blood volume (fluid volume) or blood pressure get too low, or if there is a disease that releases aldosterone inappropriately.
2. Aldosterone tells the kidneys to hold onto more water
3. Aldosterone tells the kidneys to hold onto more sodium
4. Aldosterone tells the kidneys to get rid of potassium
So 3 major things happen when aldosterone is released:
1. There is more water in the body
2. There is more sodium in the body
3. There is less potassium in the body
In this video, I'll walk you through a critical thinking exercise to help bring all of this together and help you understand it for nursing school.

OMG.... I am not in nursing school yet, im taking a&p 2....we are learning about aldosterone, abg's, m&r acidosis, and m&r alkadosis. You are the cutest first off and your videos on these topics have helped me so much. Now I am gonna go watch your video on the professors who don't teach b/c that's what I am dealing w/currently! I appreciate you!!
Than you so much! We're glad that we can help!! Thanks for being here, thehotpinkrd!
This was so simple!!! 😮 thank you for helping me pass my upcoming A&p2 exam 🙏🏽 🙏🏽
Beautiful and efficient way of explaining things. Thank you
Yay, @CelebrantServicesPortugal! We are so glad this video helped you! Thank you for your support, it means the world to us. 😊
Thank you so much! You made this really easy to understand!
So happy to hear this video was helpful for you, @Nursemtv! You will do GREAT! Thank you for being here, your support means the world to us. 😊
As a student in a BSN to DNP program having to ingest an 8.5 lb patho textbook in a matter of 16 week course, these videos are greatly appreciated!
Thanks for letting us know you loved this video, Amanda Koballa! Thank you for being here😊 Your support means the world to us!
This is simple and clear. Thank you.
Thanks for sharing such info.. I was preparing about my upcoming ttes so i got to know to watch a lecture video about antidiuretic hormone but suddenly i came here and started watching aldostereone topic videoo. But still thank you sooo much for such a great video. Your body language was impressive..❤
Thank you for letting us know you loved this video, Zainzoni Baloch007. 😊 Our favorite part of our day is hearing about how our resources have helped YOU! Your support means the world to us. 😁
Tysm for this amazing explanation it really helped me to understand the topic nicely 😊
Thank you for letting us know you loved this video, @lizlovefrv. 😊 Our favorite part of our day is hearing about how our resources have helped YOU! Your support means the world to us. 😁
Thank you. Definitely good to understand why things happen in the body so we can understand and visualize the mechanism of action of these meds!
Absolutely! It takes it from memorizing to actually learning, understanding and being able to apply it! Thanks for letting us know you loved this video, Blueskywatcher! Your support means the world to us. Thank you for being here😊
Thank you! This was a simple way for me to remember this information.
We LOVE hearing this from students, @NurseGoals24_7!! 😁😁 So happy to hear this video helped you better understand it! You are going to do FANTASTIC!
Thank you for a simple exclamation! If our Aldosterone/Renin ratio is 1.6, Aldosterone is 9, and Renin is 5.51 is that a concern? Thank you!
Hi love your videos, so helpful. You mentioned a Med sure Ck list, where can I find that?
Hey Michelle! You can get the med-surg study checklist right here >> nursingsos.lpages.co/youtube-med-surg-study-checklist/ Enjoy!! :) Thanks for being here, friend!
wow i am in 10th grade and your vedio really helped me. thank u
Underrated channel 😮
Yay! 😃Thank you for being here. Have a fantastic day 😊
Increased levels of potassium (K+) in the blood directly stimulate the production of aldosterone, a hormone produced by the adrenal cortex, through several mechanisms. Here's why:
Direct Stimulation: High levels of potassium in the plasma directly stimulate the zona glomerulosa cells of the adrenal gland to produce aldosterone. Aldosterone, in turn, increases the activity of sodium-potassium pumps and channels in the kidneys, promoting the excretion of potassium into the urine. This helps to lower the potassium levels in the blood back towards the normal range.
Electrophysiological Effects: Potassium directly affects the membrane potential of cells. High extracellular potassium concentrations decrease the membrane potential (make it less negative), which can depolarize the cells in the adrenal gland. This depolarization opens voltage-gated calcium channels, leading to an influx of calcium ions. Increased intracellular calcium is a signal that promotes the synthesis and release of aldosterone.
Renin-Angiotensin System (RAS) Modulation: While the primary trigger for aldosterone secretion in response to potassium is direct stimulation, potassium levels can also influence the activity of the renin-angiotensin system (RAS), albeit indirectly. The RAS system primarily responds to blood volume and blood pressure but interacts with aldosterone secretion pathways. High potassium levels may indirectly affect RAS components, influencing aldosterone secretion.
Feedback Mechanism: The primary role of aldosterone is to regulate blood volume and potassium levels. By stimulating aldosterone secretion, high potassium levels activate a feedback mechanism designed to restore electrolyte balance. Aldosterone increases sodium reabsorption (which helps with water retention and blood volume) and enhances potassium excretion.
This elegant feedback loop ensures that potassium levels in the blood are tightly regulated, as both hyperkalemia (high potassium levels) and hypokalemia (low potassium levels) can have serious physiological consequences, particularly for cardiac function. Hyperkalemia, for example, can lead to dangerous changes in heart rhythm, making the regulation of potassium by aldosterone crucial for maintaining cardiovascular health.
Who's stimulate the release of aldosterone?? BTW nice video 😊😊
Priyanka Pradhan, aldosterone is released by the adrenal glands. I hope that helps clarify it for you, friend! Thank you for being here, your support means the world to us!
Thanks bb. Good luck 😊
You're so welcome. Thanks for being here, Hammouche DZ!
Understood in first glance, thank you.

List some function of aldosterone
Well done
We LOVE hearing this from students, Arin Amin Zuber!! 😁😁 So happy to hear this video helped you better understand it! You are going to do FANTASTIC!
May our ALMIGHTY GOD bless you enjoyed your video as a APP x🙏🙏🙏✝️✝️✝️💚💛❤️
Thank you so much!!
Any suggestions to help me completely and fully differentiate aldosterone and ADH? Thank you for the info!
Really the key thing to know is that they both tell the kidneys to keep more fluid in the body (aldosterone does this by telling the kidneys to retain sodium). But ultimately, both of them increase fluid volume.
My doc just did a blood test and im looking at the results.. what's a healthy range for my number to be in?

Hello,
Would an imbalance in aldosterone release cause frequent urinating?
It causes an increase in the amount of potassium excreted into the urine, usually not affecting the frequency of urination. Thanks for being here, aziza turner!
