How Does Endocrinology | Adrenal Gland: Aldosterone Work?

The adrenal gland makes a hormone called aldosterone, which helps your body keep the right balance of salt and water.

Imagine you're playing with clay. You shape it into little balls, then push them through a tiny hole to make long, thin snakes, that’s like how aldosterone works in your blood vessels. It tells your kidneys, "Keep more salt inside your body!" So, when your body needs to keep water (like when you're hot or sweaty), aldosterone helps it hang on tighter.

Your body is always trying to stay balanced, like a seesaw in the playground. If you’re losing too much salt through sweat or urine, aldosterone steps in and says, "Let’s keep that salt!" This keeps your blood pressure steady and helps your body not get too dehydrated.

Think of aldosterone as a helpful friend who makes sure your body doesn’t run out of water when it needs it most. Just like how you might add more water to your glass if it starts getting low, aldosterone does something similar inside your body, all the time.
