Often it produces few symptoms. Most people have high blood pressure which may cause poor vision or headaches. Occasionally there may be muscular weakness, muscle spasms, tingling sensations, or excessive urination. Complications include cardiovascular disease such as stroke, myocardial infarction, kidney failure, and abnormal heart rhythms.Primary hyperaldosteronism has a number of causes. About 66% of cases are due to enlargement of both adrenal glands and 33% of cases are due to an adrenal adenoma that produces aldosterone. Other uncommon causes include adrenal cancer and an inherited disorder called familial hyperaldosteronism. Some recommend screening people with high blood pressure who are at increased risk while others recommend screening all people with high blood pressure for the disease. Screening is usually done by measuring the aldosterone-to-renin ratio in the blood with further testing used to confirm positive results. While low blood potassium is classically described this is only present in about a quarter of people. To determine the underlying cause medical imaging is carried out.Some cases may be cured by removing the adenoma by surgery. A single adrenal gland may also be removed in cases where only one is enlarged. In cases due to enlargement of both glands treatment is typically with medications known as aldosterone antagonists such as spironolactone or eplerenone. Other medications for high blood pressure and a low salt diet may also be needed. Some people with familial hyperaldosteronism may be treated with the steroid dexamethasone.Primary aldosteronism is present in about 10% of people with high blood pressure. It occurs more often in women than men. Often it begins in those between 30 and 50 years of age. Conn's syndrome is named after Jerome W. Conn (1907–1994), the American endocrinologist who first described adenomas as a cause of the condition in 1955."@en }
