Aldosterone hormone

Aldosterone is a hormone produced by your adrenal glands, which are located on top of your kidneys. Its main job is to help regulate the balance of salt and water in your body. When your body needs to hold on to more salt and water, like when you're low on fluids or your blood pressure is low, aldosterone tells your kidneys to reabsorb more salt and water from your urine. This helps increase your blood pressure and maintain the right balance of these substances in your body. So, in simple terms, aldosterone helps control your body's salt and water levels to keep things in balance.
