Some people with mild cases of hyperaldosteronism have no symptoms (are asymptomatic). The symptoms of hyperaldosteronism can vary based on the severity of the condition. What are the signs and symptoms of hyperaldosteronism? Experts estimate that as many as 25% of people who have medication-resistant high blood pressure may have hyperaldosteronism. Some studies suggest that 5% to 10% of people with high blood pressure have primary hyperaldosteronism.

It’s difficult for researchers to estimate how common hyperaldosteronism is. It more often affects people assigned female at birth than people assigned male at birth. Hyperaldosteronism mostly affects people 30 to 50 years old. Hyperaldosteronism causes high blood pressure (hypertension) and low potassium levels in your blood.

Secondary hyperaldosteronism: An issue somewhere else in your body causes your adrenal glands to make too much aldosterone.

Primary hyperaldosteronism (Conn’s syndrome): An issue within your adrenal glands causes them to release too much aldosterone.

There are two main types of hyperaldosteronism: You have two adrenal glands - one atop each kidney. They make hormones your body needs to carry out daily functions. Your adrenal glands are part of your endocrine system. Aldosterone is a hormone that helps regulate your blood pressure by controlling the levels of potassium and sodium in your blood. Hyperaldosteronism is a condition in which one or both of your adrenal glands produce too much aldosterone.

Hyperaldosteronism happens when one or both of your adrenal glands produce too much aldosterone, a hormone.
