Summary
Conn syndrome, also known as primary hyperaldosteronism, is a rare disorder caused by high levels of aldosterone hormone. Aldosterone is produced by the adrenal gland, promotes Sodium conservation in the kidney, and helps the body keep Sodium and water balance.
In Conn syndrome, the adrenal gland produces too much aldosterone, and this causes the body to retain too much salt and water. This can lead to high blood pressure, edema, and hypokalemia (low potassium levels in the blood). Conn syndrome can be caused by adrenal hyperplasia or adrenal adenoma.
