Description

Primary hyperaldosteronism, another name for Conn syndrome, describes excessive aldosterone secretion. By controlling the levels of sodium and potassium in the kidney, aldosterone, which is released by the adrenal glands, is a key component in the management of blood pressure. Aldosterone promotes water reabsorption into the blood vessels by promoting potassium excretion into the urine and salt reabsorption back into the circulation. High blood pressure might result from water entering the circulation in large amounts. In addition, abnormal pulses and muscle cramps might result from low potassium levels. Renin is a protein that normally controls the production of aldosterone. However, in people with Conn syndrome, aldosterone levels are increased despite normal renin levels. The long-term effects of Conn syndrome make it possible to classify it as serious. uncontrolled hypertension Untreated hypertension can result in an increased chance of developing heart failure, heart attacks, kidney failure, and strokes. Additionally, the related hypokalemia, or low potassium levels, can cause an erratic heartbeat. Aldosterone is overproduced in Conn syndrome, also known as primary hyperaldosteronism. The hormone aldosterone, which is secreted by the adrenal glands, controls sodium and potassium levels to control blood pressure. It can become a significant issue if left untreated because high blood pressure raises the possibility of developing a wide range of other health issues. Adrenal tumors (adenomas) or bilateral adrenal hyperplasia are two common causes of Conn syndrome. Individuals frequently develop hypertension that is resistant to blood pressure treatment. They might also have cramps, headaches, excessive urination, and blurred vision. Conn syndrome can be diagnosed via imaging scans, suppression tests, and blood tests. Conn syndrome can be treated in one of two ways, depending on the underlying cause: taking medicine to regulate aldosterone levels or having a tumor that produces aldosterone. Conn syndrome is inherited. Although Conn syndrome itself is not inherited, it can be brought on by a hereditary disorder, such as bilateral adrenal hyperplasia. In patients who acquire hyperaldosteronism before the age of 20 or in those under the age of 40 with a family history of stroke or hyperaldosteronism, medical professionals frequently desire to undertake genetic testing.

Conn syndrome is recognized. A Conn syndrome diagnosis often starts with a thorough medical history and physical examination. After that, medical professionals would probably run blood tests to evaluate a patient's hormone and electrolyte levels. Conn syndrome can be identified specifically by measuring aldosterone, renin, sodium, and potassium levels. Adrenal vein sampling, which involves drawing blood from the adrenal veins using a catheter to compare the hormone levels produced by each individual adrenal gland, may also be desired by some healthcare professionals. A suppression test might be employed in some circumstances to assess if the body is producing too much aldosterone or not. Saline or captopril suppression tests are just two examples of the several types of suppression tests. An individual will get an IV salt solution for the saline suppression test, and their aldosterone level will be checked. In a similar vein, in the captopril suppression test, also known as the captopril challenge test, a person is given the blood pressure-lowering drug captopril, and as a result, their aldosterone levels are measured.

Causes

An adrenal tumor, such as adenomas that produce aldosterone, is the most common cause of Conn syndrome. These tumors are often benign but can occasionally be cancerous. Bilateral adrenal hyperplasia, a hereditary condition that affects the production of hormones in the adrenal glands, can less frequently induce Conn syndrome.

Treatment

The underlying reason will determine how Conn syndrome is treated in most cases. Aldosterone-producing adenomas and other adrenal tumors can frequently be removed surgically using a laparoscopic technique. On the other hand, drugs that block aldosterone, like spironolactone, can be used to treat bilateral adrenal hyperplasia. Most of the time, people are also advised to keep up a low-salt diet, give up smoking, consume less alcohol, and exercise frequently.

Symptoms

Conn syndrome most frequently results in high blood pressure that is resistant to treatment with blood pressure medicines. Other symptoms and indicators include nocturia, or the need to urinate at night; extreme thirst; and increased frequency of urination. In addition, people may also have headaches, dizziness, blurred vision, weakness or tingling, and muscle cramps.
