Key Points about Conn’s Syndrome:

  • Definition: Conn’s Syndrome, also known as primary hyperaldosteronism, is a condition characterized by excessive production of aldosterone from the adrenal glands, leading to hypertension and hypokalemia.
  • Causes: The most common cause is an aldosterone-producing adenoma (benign tumor) of the adrenal gland. Bilateral adrenal hyperplasia is another cause.
  • Symptoms: Symptoms include hypertension that is often resistant to treatment, muscle weakness, fatigue, and in severe cases, metabolic alkalosis due to low potassium levels.
  • Diagnosis: Diagnosis involves measuring plasma aldosterone concentration (PAC) and plasma renin activity (PRA), with a high aldosterone-to-renin ratio being indicative of the condition. Imaging and adrenal vein sampling may be used to localize the source of excess aldosterone.
  • Management: Treatment includes surgical removal of the adenoma (if present) or medical management with aldosterone antagonists like spironolactone for patients with bilateral hyperplasia or those not suitable for surgery.
  • Complications: Untreated Conn’s Syndrome can lead to severe cardiovascular complications, including heart failure, stroke, and chronic kidney disease due to prolonged hypertension.
