The Sneaky Hormone Driving Your High Blood Pressure
13 May
Summary
- Aldosterone, a hormone from adrenal glands, regulates blood pressure.
- Excess aldosterone causes water and sodium retention, raising blood pressure.
- Testing and lifestyle changes can manage aldosterone-related hypertension.
High blood pressure, often associated with diet and exercise, can also be influenced by a hormone known as aldosterone. This hormone, produced by the adrenal glands atop the kidneys, plays a crucial role in regulating sodium, water, and potassium balance. When aldosterone levels are too high, the body retains excess sodium and water, leading to elevated blood pressure.
Beyond increasing blood pressure, excessive aldosterone can directly harm blood vessels, the heart, and kidneys, potentially increasing risks of atrial fibrillation and heart failure. While previously thought to only affect severe cases with low potassium, experts now recognize that normal potassium levels can accompany high aldosterone. Common causes include non-cancerous adrenal tumors or the body compensating for other conditions.
Individuals with difficult-to-control high blood pressure, low potassium, or suspected endocrine hypertension may benefit from aldosterone testing. Treatment options include surgery for tumors or medications that block aldosterone's effects. Lifestyle changes such as reducing sodium intake, improving sleep, and regular exercise are also vital for managing aldosterone-related hypertension.
