Primary Aldosteronism

Primary Aldosteronism (PA) is a condition where your adrenal glands, which sit on top of your kidneys, produce too much of a hormone called aldosterone. Aldosterone plays a crucial role in regulating your blood pressure and potassium levels. When there's an excess of aldosterone, it causes your body to retain more salt and water, leading to high blood pressure (hypertension) that can be difficult to control, and often, but not always, low potassium levels. This form of high blood pressure can increase your risk for serious health problems, including heart attack, stroke, and kidney disease, more so than other forms of high blood pressure. The most common causes of Primary Aldosteronism include a non-cancerous growth (adenoma) on one adrenal gland, often referred to as Conn's syndrome, or overactivity in both adrenal glands, known as bilateral adrenal hyperplasia. Less commonly, it can be caused by adrenal cancer or inherited conditions. It's important to differentiate PA from other types of high blood pressure because it requires specific diagnostic approaches and treatments. Your doctor has ordered lab tests, such as measurements of aldosterone and renin (another hormone that interacts with aldosterone), to investigate your condition. These tests are essential to confirm if you have Primary Aldosteronism and, if so, to help determine the specific cause. Identifying the exact cause is critical because it guides the most effective treatment plan, which can range from specific medications to, in some cases, surgical removal of an affected adrenal gland. Early diagnosis and appropriate treatment can significantly improve blood pressure control and help prevent long-term complications.
