Primary aldosteronism treatment: medication or adrenal surgery?
Primary aldosteronism can be treated with medicines that block aldosterone's effects or, in selected people with one-sided disease, removal of the affected adrenal gland. The decision depends on where excess aldosterone comes from, your fitness for surgery and your preferences. A CT nodule alone may not identify the hormone-producing side. Ask the endocrine team how it established the diagnosis and whether adrenal vein sampling would help choose between medication and surgery.

Understand what treatment is trying to change
Excess aldosterone can drive high blood pressure and, in some people, low potassium. Treatment aims to control that hormone effect as well as the blood pressure reading. Normal potassium does not exclude the condition.
Ask your clinician to show you the aldosterone, renin and potassium results and explain how medicines or testing conditions were considered. If a result needs repeating, get preparation instructions in writing. Never remove several blood pressure medicines from your routine on your own to prepare for testing.
Establish whether one or both glands are involved
A scan shows the structure of the adrenal glands. Adrenal vein sampling measures hormone production from each side and is often used when surgery is being considered. Small nodules on imaging can be misleading about which gland is responsible.
Ask what confidence the team has in one-sided disease and whether you are among the selected patients who may not need sampling. If sampling is proposed, discuss how the procedure is performed, its risks and what happens if the result is inconclusive. The answer should help decide treatment, not simply add another test.
When medication is the practical choice
Medication is commonly used for bilateral disease and for people who prefer to avoid surgery or are not suitable candidates. Mineralocorticoid receptor antagonists, including spironolactone or an alternative such as eplerenone, block aldosterone's action.
Ask about the initial dose, laboratory monitoring and possible side effects. Potassium can become too high, and kidney function needs monitoring. Tell the prescriber about potassium supplements and other blood pressure medicines. If side effects become troublesome, contact the team to review the regimen rather than abandoning treatment.
When an operation is worth discussing
If testing shows excess production mainly from one gland and you are a suitable surgical candidate, adrenalectomy may be considered. Discuss the expected hormonal outcome separately from the chance of reducing or stopping blood pressure medicines.
Ask which gland will be removed, why the evidence points to that side and what the operation and recovery involve. The surgeon should explain your individual risks and the plan for postoperative blood pressure and potassium checks. Bring up work, caring duties and follow-up near home while comparing the options.
Review the wider adrenal assessment
An adrenal nodule can also prompt evaluation of cortisol production. This can affect the interpretation of testing and the planning of care after surgery. Ask whether your assessment has addressed the hormones relevant to your finding.
Keep each laboratory result with its collection details rather than sending a list of abnormal values alone. If another clinic has recommended surgery from the scan alone, request an explanation of how the hormone-producing side was established. A review can clarify whether further testing would materially change that recommendation.
Follow the response whichever treatment you choose
Record home blood pressure as instructed and bring the readings to review. Ask when potassium and kidney function should be checked after a medication change or surgery. Your prescriber may need to reduce other medicines as treatment takes effect.
For ongoing medical treatment, the team may also review renin alongside blood pressure and laboratory safety results. Ask what target they are using and why. After surgery, request a written follow-up plan and know who will discuss persistent hypertension or an unexpected potassium result.
Prepare an adrenal consultation in Shanghai
Ruijin Hospital has endocrinology services and is a Shanghai resource for reviewing an adrenal hormone diagnosis. The useful starting question is whether your results support medical treatment or a further assessment for surgery.
EastMedGo can help organize your laboratory history, scan reports and any adrenal vein sampling report for an inquiry. Include current doses and the main difficulty, such as side effects or persistent hypertension. We can clarify the proposed clinic, required records and coordination arrangements before travel is planned.

Common questions
If only one adrenal nodule appears on CT, can it simply be removed?
The hormone-producing side often needs confirmation beyond CT. Ask whether adrenal vein sampling is appropriate before a surgical decision.

Will adrenal surgery cure my high blood pressure?
It may improve blood pressure and reduce medication needs, but the hormonal result and blood pressure result are assessed separately. Discuss your likely outcome and continued monitoring.
