Hyperaldosteronism is a medical condition wherein too much aldosterone is produced. High aldosterone levels can lead to lowered levels of potassium in the blood (hypokalemia) and increased hydrogen ion excretion . Aldosterone is normally produced in the adrenal glands.
Other medications for high blood pressure and a low salt diet, e.g. DASH diet, may also be needed. [1] [4] Some people with familial hyperaldosteronism may be treated with the steroid dexamethasone. [1] Primary aldosteronism is present in about 10% of people with high blood pressure. [1] It occurs more often in women than men. [5]
Familial hyperaldosteronism is a group of inherited conditions in which the adrenal glands, which are small glands located on top of each kidney, produce too much of the hormone aldosterone. [1] Excess aldosterone causes the kidneys to retain more salt than normal, which in turn increases the body's fluid levels and causes high blood pressure. [1]
Conn's Syndrome, also known as primary aldosteronism, is a condition that causes high blood pressure due to excessive production of the hormone aldosterone by the adrenal glands.
Aldosterone release causes sodium and water retention, which causes increased blood volume, and a subsequent increase in blood pressure, which is sensed by the baroreceptors. [39] To maintain normal homeostasis these receptors also detect low blood pressure or low blood volume, causing aldosterone to be released.
Aldosterone is increased by blood loss, pregnancy, and possibly by other circumstances such as physical exertion, endotoxin shock, and burns. Aldosterone feedback : [ citation needed ] Feedback by aldosterone concentration itself is of a non-morphological character (that is, other than changes in cell number or structure) and is relatively poor ...
Angiotensin II also causes the adrenal glands to release aldosterone, which stimulates the epithelial cells of the kidneys to increase re-absorption of salt and water, leading to raised blood volume and raised blood pressure. So elevated renin levels in the blood (normally 1.98-2.46 ng/ml in the upright position) [40] leads to hypertension. [2 ...
This in turn results in an increase of blood pressure and blood volume. Aldosterone is produced in the zona glomerulosa of the cortex of the adrenal gland and its secretion is mediated principally by angiotensin II but also by adrenocorticotrophic hormone (ACTH) and local potassium levels.
