Primary aldosteronism
Primary aldosteronism (PA), also known as primary hyperaldosteronism, is the excess production of the hormone aldosterone from the adrenal glands, resulting in low renin levels and high blood pressure. This abnormality is a paraneoplastic syndrome (i.e. caused by hyperplasia or tumors). About 35% of the cases are caused by a single aldosterone-secreting adenoma, a condition known as Conn's syndrome. Many patients experience fatigue, potassium deficiency and high blood pressure which may cause poor vision, confusion or headaches. Symptoms may also include: muscular aches and weakness, muscle spasms, low back and flank pain from the kidneys, trembling, tingling sensations, dizziness/vertigo, nocturia and 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 33% of cases are due to an adrenal adenoma that produces aldosterone, and 66% of cases...
