Aldosterone is a hormone made by the adrenal cortex. Its main role is to keep your body’s salt and water balance in check, which directly affects blood pressure. It acts on the kidneys, telling them to hold on to sodium (salt) and water while excreting extra potassium. By doing this, aldosterone helps maintain proper fluid levels and ensures stable blood pressure.

Key Functions of Aldosterone

• Regulates salt and water balance: keeps the right amount of fluids in the body.
• Maintains blood pressure: prevents sudden drops or rises by controlling fluid volume.
• Balances electrolytes: conserves sodium, excretes potassium.

Supports circulation: ensures enough blood reaches vital organs.
