Symptoms

Primary aldosteronism often doesn't cause clear symptoms. The first clue that you may have primary aldosteronism is usually high blood pressure, especially hard to control blood pressure.

Sometimes, primary aldosteronism causes low potassium levels. If this happens, you may have:

• Muscle cramps
• Weakness
• Fatigue
• Headache
• Excessive thirst
• A frequent need to urinate

When to see a doctor

Ask your doctor about the possibility of having primary aldosteronism if you have:

• Moderate to severe high blood pressure, especially if you need many medications to control your blood pressure
• High blood pressure and a family history of primary aldosteronism
• High blood pressure and a family history of high blood pressure or stroke at age 40 or younger
• High blood pressure and a growth on one of your adrenal glands (found in an imaging test done for another reason)
• High blood pressure and a low potassium level
• High blood pressure and obstructive sleep apnea
