Aldosterone can also be measured using a urine test.Read Article Now Book Mark Article Hyperaldosteronism can be primary or secondary. Causes Hyperaldosteronism occurs when the adrenal glands release too much aldosterone.Primary hyperaldosteronism is due to a problem of the adrenal glands themselves. Most cases are caused by a noncancerous (benign) tumor of the adrenal gland.Secondary hyperaldosteronism is due to a problem elsewhere in the body that causes the adrenal glands to release too much aldosterone. These problems can be with:Genes Diet Medical disorders such as with the heart, liver, kidneys, or high blood pressureThe condition mostly affects people 30 to 50 years old and is a common cause of high blood pressure in middle age. Symptoms Primary and secondary hyperaldosteronism have common symptoms, including:High blood pressure Low level of potassium in the blood Feeling tired all the time Headache HeadacheA headache is pain or discomfort in the head, scalp, or neck.

Your provider will tell you what to do before the procedure.Another procedure involves inserting a catheter into the veins of the adrenal glands. This helps check which of the two adrenal glands is making too much aldosterone. This test is important because many people have small benign tumors in the adrenal glands that do not secrete any hormones. Relying only on a CT scan may result in the wrong adrenal gland being removed. Treatment Primary hyperaldosteronism caused by an adrenal gland tumor is often treated with surgery. It can sometimes be treated with medicines.TumorA tumor is an abnormal growth of body tissue. Tumors can be cancerous (malignant) or noncancerous (benign).Read Article Now Book Mark Article Removing the adrenal tumor may control the symptoms. Even after surgery, some people still have high blood pressure and need to take medicine. But often, the number of medicines or doses can be lowered.Limiting salt intake and taking medicine may control the symptoms without surgery. Medicines to treat hyperaldosteronism include:Medicines that block the action of aldosterone Water pills (diuretics), which help manage fluid buildup in the bodySecondary hyperaldosteronism is treated with medicines (as described above) and limiting salt intake. Surgery is usually not used. Outlook (Prognosis) The outlook for primary hyperaldosteronism is good with early diagnosis and treatment.The outlook for secondary hyperaldosteronism depends on the cause of the condition. Possible Complications Primary hyperaldosteronism can cause very high blood pressure, which can damage many organs, including the eyes, kidneys, heart, and brain.Erection problems and enlarged breast tissue in men (gynecomastia) may occur with long-term use of medicines to block the effect of hyperaldosteronism.GynecomastiaWhen abnormal breast tissue develops in males, it is called gynecomastia.

For instance, the pancreas secretes insulin, which allows the body to regulate levels of sugar in the blood. The thyroid gets instructions from the pituitary to secrete hormones which determine the rate of metabolism in the body (the more hormone in the bloodstream, the faster the chemical activity; the less hormone, the slower the activity).Endocrine glandsillustrationAdrenal gland hormone secretion - illustration The adrenal gland secretes steroid hormones such as cortisol and aldosterone. It also makes precursors that can be converted to sex steroids (androgen, estrogen). A different part of the adrenal gland makes adrenaline (epinephrine). When the glands produce more or less hormones than required by the body, disease conditions may occur.Adrenal gland hormone secretionillustrationEndocrine glands - illustration Endocrine glands release hormones (chemical messengers) into the bloodstream to be transported to various organs and tissues throughout the body.
