Hyperaldosteronism is a type of hormone disorder in which the adrenal glands produce excessive aldosterone increasing its level in the blood. Aldosterone balances the sodium and potassium in the blood. Hyperaldosteronism causes the adrenal glands to produce an increased amount of aldosterone, which leads to sodium retention. This leads to high blood pressure. There are two types of hyperaldosteronism:

  • Primary hyperaldosteronism occurs due to a problem with the adrenal gland causing them to produce increased amounts of aldosterone. These problems include a benign growth in an adrenal gland which produces aldosterone (Conn’s syndrome) and over activity of both adrenal glands (idiopathic hyperaldosteronism).  

  • Secondary hyperaldosteronism occurs due to a problem elsewhere in the body that prompts the adrenal glands to produce increased amounts of aldosterone. Example of such a scenario is the presence of a renin-producing tumour which leads to increased aldosterone levels, since renin regulates the body’s aldosterone levels. Other causes can be genetic disorder, dietary habits or another medical disorder.​

Symptoms for hyperaldosteronism include:

Ideally, you should have your blood pressure regularly checked especially if:

  • You are in your forties

  • You have a family history of high blood pressure

  • You do not exercise regularly or at all

  • You smoke

  • You are overweight

  • You have unhealthy eating habits (too much salt intake)

  • You consume too much alcohol

Visit a doctor at the Internal Medicin​e Service Line​ at the Aga Khan University Hospital, for expert diagnosis to determine the underlying cause of high blood pressure.​​​

Your time with your doctor maybe limited, so make sure to prepare for your visit beforehand. Here are some tips to help get you started.

Your doctor may begin the diagnosis with an evaluation of your medical history and discussion about your symptoms. Following this you may be asked to get the following tests conducted:

  • Blood test to determine the levels of certain hormones and chemicals in your blood stream, including:​

    • ​Aldosterone

    • Renin

    • Potassium

  • Urine test in which you will be asked to collect your urine for the length of one day to measure the amount of aldosterone removed in the urine in a day

  • Abdominal computerized tomography (CT) scan in which a series of detailed cross-sectional images, of the abdomen, are taken by a computer using X-rays​

The goal of your treatment is to either normalize the aldosterone levels or block its effects. Your treatment options will be based on the underlying cause of hyperaldosteronism. Generally, the treatments available include:

  • Surgery to remove the adrenal gland (adrenalectomy) in case of the presence of an aldosterone secreting tumour on the gland 

  • Aldosterone-blocking drug that blocks the action of the aldosterone. Medications are preferable if you want to avoid or cannot undergo surgery

  • Lifestyle changes. Medications are only effective if you change your lifestyle as well. You should increase the intake of a healthy well-balanced diet and exercise regularly ​​
