aldosterone
Adrenal salt regulator
Aldosterone is a hormone produced by the adrenal glands that regulates sodium and potassium balance in the body.
It signals the kidneys to retain salt and excrete potassium, which affects blood pressure and fluid balance.
Conditions involving too much or too little aldosterone can cause hypertension or dangerous electrolyte imbalances.
