Aldosterone is a salt corticosteroid secreted by the adrenal cortex, and its main role is to maintain the body’s water electrolyte metabolism, among other things. Aldosterone is secreted by the adrenal cortex and acts mainly on the distal tubules of the kidney to promote the reabsorption of sodium and chloride ions and the excretion of hydrogen and potassium ions. At the same time, aldosterone also acts on the salivary glands, sweat glands, muscles and mucous membranes of the gastrointestinal tract, causing them to retain sodium and potassium. Under normal physiological conditions, the daily secretion of aldosterone is small. If aldosterone secretion increases due to adrenocortical hyperplasia, etc., it can cause hypokalemia, tissue edema, and hypertension. If the secretion of aldosterone decreases due to hypoadrenocorticism, it may cause lower blood pressure. If there is any discomfort, it is recommended to consult a doctor in time for diagnosis and treatment.
