This month we are going to be talking about Conn’s Syndrome, a disease caused by a tumor in the adrenal glands that is producing too much of the hormone aldosterone.
One of the functions of your adrenal glands is to produce a hormone called aldosterone that plays an active role in your blood pressure. It does this by maintaining the balance of sodium, potassium, and water in your blood. Hyperaldosteronism is an endocrine disorder that involves one or both of your adrenal glands creating too much of a hormone called aldosterone. This causes your body to lose too much potassium and retain too much sodium, which increases water retention, blood volume, and blood pressure.
The main symptom of hyperaldosteronism is high blood pressure, which can range from moderate to severe. In some cases, high blood pressure related to hyperaldosteronism doesn’t respond to medication. In others, it may only respond to a certain combination of medications.
High blood pressure does not typically have symptoms. But when it does, they can include: headaches, dizziness, vision problems, chest pain and shortness of breath.
The other main symptom of hyperaldosteronism is hypokalemia, which refers to low potassium levels in your blood. While it doesn’t always cause symptoms, more moderate cases of hypokalemia may cause: fatigue, muscle cramps, increased thirst, increased urination, muscle weakness or palpitations.
No. Conn's Syndrome is not rare, it is common, typically occurring in patients over 30 years of age. It used to be thought that primary hyperaldosteronism was very rare but we see a patient with Conn's several times per week. The reason Conn's Syndrome was thought to be rare is that many doctors did not know about it or were not tested for it because many patients were not feeling very sick and so the disease was not being diagnosed and the patients were just treated with highblood pressure pills (anti-hypertensives).
Unfortunately, over time having too much aldosterone being produced by your adrenal gland damages your heart, blood vessels and brain. But most doctors were not actively screening their patients with high blood pressure to find the disease. They should, as you will learn as you read on.
There are two types of hyperaldosteronism, known as primary and secondary hyperaldosteronism. While they have similar symptoms, their causes are different.
Primary hyperaldosteronism is caused by a problem with one or both adrenal glands. It’s sometimes referred to as Conn’s syndrome. Some people are born with overactive adrenal glands. Others might have it due to: a benign tumor on
one of the adrenal glands, adrenocortical cancer, which is a rare aldosteroneproducing cancerous tumor, glucocorticoid-remediable aldosteronism, a type of aldosteronism that runs in families and other types of inheritable issues that affect the adrenal glands.
Secondary hyperaldosteronism is caused by something outside the adrenal glands. It’s usually related to reduced blood flow to your kidneys. Several things can cause this, including: a blockage or narrowing of the renal artery, chronic liver disease, heart failure and diuretic medications.
If you have symptoms of hyperaldosteronism, we at Palmetto Endocrinology will likely start by doing a blood test to check your levels of aldosterone and renin, an enzyme released by your kidney that works with aldosterone to help balance blood pressure. People with hyperaldosteronism generally have low renin levels and high aldosterone levels.
Depending on the results of your blood test, we might run some other tests, including:
If you already take medication for high blood pressure, we might ask you to stop taking it for a brief period of time while they do these tests.
Treating hyperaldosteronism focuses on reducing your aldosterone levels or blocking the effects of aldosterone, high blood pressure, and low blood potassium. There are several ways to do this, depending on what’s causing your hyperaldosteronism.
High levels of aldosterone can cause a variety of health problems. ResearchTrusted Source, which is based in Oxford, England shows it can cause direct injury to heart tissues, leading to scarring and enlargement of the left side of the heart. In addition to injuring blood vessels and causing other complications related to high blood pressure, untreated hyperaldosteronism can put you at greater risk for: heart attacks, heart failure, stroke and kidney failure.
To avoid complications, work with us to come up with a long-term treatment plan
for your high blood pressure. Make sure to regularly follow up to check for any changes in your blood potassium levels as well.
While the effects of hyperaldosteronism can lead to complications over time, the condition itself can be managed with the right treatments. For many people, the best plans involve a combination of surgery, medication, and lifestyle changes. We at Palmetto Endocrinology are well versed and ready to help you.
