What Is Aldosterone?
Aldosterone is a hormone produced by the adrenal glands, which sit on top of the kidneys. It helps regulate blood pressure by controlling the balance of sodium, potassium, and water in the body. By affecting how much sodium and water the kidneys retain or remove, aldosterone plays an essential role in maintaining healthy blood pressure and fluid balance.
Abnormal aldosterone levels can contribute to high blood pressure, electrolyte imbalances, and certain endocrine disorders.
Why Aldosterone Matters
Proper aldosterone function helps maintain healthy blood pressure, supports normal nerve and muscle function, and keeps electrolyte levels within a healthy range. Too much or too little aldosterone may lead to serious health problems if left untreated.
Functions of Aldosterone
- Regulates sodium levels
- Controls potassium balance
- Maintains fluid balance
- Helps regulate blood pressure
- Supports kidney function
- Maintains healthy blood volume
Conditions Associated with Abnormal Aldosterone Levels
- Primary aldosteronism
- Adrenal gland disorders
- High blood pressure
- Heart failure
- Kidney disease
- Addison’s disease
How Are Aldosterone Levels Evaluated?
Healthcare providers measure aldosterone using blood or urine tests. Results are often interpreted together with renin levels, electrolyte testing, blood pressure measurements, and additional hormone studies to identify the underlying cause of abnormal results.
How Home Care Can Help
Home care professionals support individuals with hormonal and cardiovascular disorders by encouraging medication adherence, monitoring blood pressure, promoting healthy nutrition, observing for signs of fluid imbalance, and communicating changes in health to healthcare providers.
Home Care Tip
If you have a condition affecting aldosterone levels, take medications exactly as prescribed and attend regular follow-up appointments to monitor blood pressure and electrolyte levels.
Frequently Asked Questions About Aldosterone
What does aldosterone do?
Aldosterone helps regulate blood pressure by controlling the balance of sodium, potassium, and water in the body.
Can high aldosterone cause high blood pressure?
Yes. Excess aldosterone can cause the body to retain sodium and water, leading to elevated blood pressure.
Can aldosterone disorders be treated?
Yes. Treatment depends on the underlying cause and may include medications, lifestyle changes, or surgery for certain adrenal gland disorders.
When to Contact Your Healthcare Provider
Speak with your healthcare provider if you have difficult-to-control high blood pressure, unexplained muscle weakness, abnormal potassium levels, or symptoms of an adrenal gland disorder.
