E26.01
Conn's syndrome
Clinical Classification Guidelines
Code Also
- adrenal adenoma (D35.0-)
Medical Intelligence & Overview
Conn's syndrome, also known as primary hyperaldosteronism, is a condition characterized by the overproduction of the hormone aldosterone by the adrenal glands. This hormone plays a vital role in regulating blood pressure, sodium, and potassium levels in the body. Excess aldosterone can lead to high blood pressure and imbalances in electrolytes, which may cause various health issues if left untreated. Conn’s syndrome is most commonly caused by benign tumors in the adrenal glands but can also result from other adrenal-related conditions.
Causes & Symptoms
Clinical Causes: Aldosterone-producing adenoma (benign tumor in one adrenal gland) Bilateral adrenal hyperplasia (enlargement of both adrenal glands) Adrenal hyperplasia or other adrenal gland abnormalities Rarely, genetic factors or familial syndromes Unknown causes in some cases
Key Symptoms: High blood pressure (hypertension), often resistant to medication Muscle weakness or cramps due to electrolyte imbalances Frequent urination or increased thirst Headaches Fatigue or weakness Paresthesias (abnormal sensations like tingling) Persistent numbness, particularly in the extremities Vision problems, sometimes related to high blood pressure
Diagnostic & Treatment
Diagnosis Path: Diagnosing Conn’s syndrome involves a combination of laboratory tests and imaging studies. Initial blood tests may reveal elevated levels of aldosterone and low levels of renin. Confirmatory testing often includes salt loading tests or suppression tests to assess aldosterone regulation. Imaging studies such as CT scans or MRI of the adrenal glands can identify tumors or hyperplasia. More specialized adrenal vein sampling may be performed to determine if one or both glands are overproducing aldosterone. Accurate diagnosis is essential for guiding appropriate treatment options.
Treatment Protocols: Treatment options for Conn’s syndrome depend on the underlying cause. Surgical removal of the affected adrenal gland (adrenalectomy) is typically recommended for patients with a detected adrenal tumor. Medical management with mineralocorticoid receptor antagonists like spironolactone or eplerenone can be effective, especially in cases of bilateral adrenal hyperplasia or when surgery is not suitable. Managing blood pressure and electrolyte imbalances through medication and lifestyle modifications is an integral part of treatment. Close medical follow-up is essential to monitor the condition and prevent complications.
