Question: What Does Aldosterone Test For?

Is Conn’s Syndrome serious?

Without proper treatment, patients with hyperaldosteronism often suffer from poorly controlled high blood pressure and are at increased risk for heart attacks, heart failure, strokes, kidney failure, and early death.

However, with appropriate treatment, this disease is treatable and has an excellent prognosis..

What does aldosterone do in the body?

The adrenal glands, located atop each kidney, secrete many hormones, including aldosterone. Aldosterone helps the kidneys manage water, sodium, and potassium. Too much aldosterone can cause the kidneys to retain water and sodium and flush potassium.

What happens when aldosterone levels are high?

In hyperaldosteronism, overproduction of aldosterone leads to fluid retention and increased blood pressure, weakness, and, rarely, periods of paralysis. Hyperaldosteronism can be caused by a tumor in the adrenal gland or may be a response to some diseases.

What are the symptoms of low aldosterone?

Signs and symptoms may include:Extreme fatigue.Weight loss and decreased appetite.Darkening of your skin (hyperpigmentation)Low blood pressure, even fainting.Salt craving.Low blood sugar (hypoglycemia)Nausea, diarrhea or vomiting (gastrointestinal symptoms)Abdominal pain.More items…•

What does high renin and aldosterone mean?

High renin with normal aldosterone may show that you’re sensitive to salt. Low renin and high aldosterone may mean your adrenal glands aren’t working the way they should. If both are high, it can be a sign that there’s a problem with your kidneys.

How long do aldosterone test results take?

Results are usually available in 2 to 5 days. An overgrowth of normal cells in the adrenal glands (called adrenal hyperplasia) or a tumor of the adrenal glands affects the adrenal glands directly and causes a condition called primary aldosteronism.

How does aldosterone affect the heart?

Aldosterone excess, whether from genetic causes or primary aldosteronism (hyperplasia or aldosterone-secreting adenomas), is well documented to cause hypertension. Hypertension, in turn, has significant adverse effects on the cardiovascular system, including left ventricular hypertrophy and cardiac fibrosis.

Can stress cause high aldosterone levels?

Psychological stress also activates the sympathetic-adrenomedullary system which stimulates rennin release leading to increases in angiotensin II and aldosterone secretion. Aldosterone activates MR which in turn may lead to vascular injury and inflammation, and ultimately heart disease, renal disease, and stroke.

Can too much aldosterone cause weight gain?

Fast-growing tumors sometimes cause the adrenal gland to produce elevated levels of aldosterone, cortisol, and adrenal sex hormones such as androgen. Symptoms of adrenocortical carcinoma—such as high blood pressure, weight gain, and diabetes—can easily be attributed to or confused with many other medical problems.

What are the signs of adrenal gland problems?

What are the symptoms of adrenal gland disorders?Upper body obesity, round face and neck, and thinning arms and legs.Skin problems, such as acne or reddish-blue streaks on the abdomen or underarm area.High blood pressure.Muscle and bone weakness.Moodiness, irritability, or depression.High blood sugars.Slow growth rates in children.

What triggers aldosterone release?

Aldosterone secretion is stimulated by an actual or apparent depletion in blood volume detected by stretch receptors and by an increase in serum potassium ion concentrations; it is suppressed by hypervolemia and hypokalemia.

What is a aldosterone blood test for?

What is an aldosterone (ALD) test? This test measures the amount of aldosterone (ALD) in your blood or urine. ALD is a hormone made by your adrenal glands, two small glands located above the kidneys. ALD helps control blood pressure and maintain healthy levels of sodium and potassium.

What is the most common cause of hyperaldosteronism?

Most cases of primary hyperaldosteronism are caused by a noncancerous (benign) tumor of the adrenal gland. The condition mostly affects people 30 to 50 years old and is a common cause of high blood pressure in middle age.

Is aldosterone a stress hormone?

The adrenal cortex—the outer part of the gland—produces hormones that are vital to life, such as cortisol (which helps regulate metabolism and helps your body respond to stress) and aldosterone (which helps control blood pressure).

What happens when aldosterone is blocked?

It’s also possible to have low levels of aldosterone. Primary adrenal insufficiency, a disease that causes a general loss of adrenal function, can be a cause. Patients with primary adrenal insufficiency causing low levels of aldosterone may experience low blood pressure, increased potassium levels, and lethargy.
