ADH vs. Aldosterone: Difference and Comparison
Edited by Muazma Batool — By Muneeza Rehman — Published on November 10, 2023
ADH (Antidiuretic Hormone) regulates water balance, while Aldosterone regulates sodium and potassium balance.
Difference Between ADH and Aldosterone
ADH, or antidiuretic hormone, and aldosterone are critical hormones for regulating bodily fluids. ADH primarily focuses on controlling the water balance in the body by acting on the kidneys to retain water. Aldosterone, on the other hand, manages electrolyte balance, ensuring sodium retention and potassium excretion.

The release of ADH, synthesized in the hypothalamus and stored in the pituitary gland, is triggered mainly by an increase in blood osmolality or a decrease in blood volume. Aldosterone is produced in the adrenal cortex and its release is largely influenced by the renin-angiotensin-aldosterone system, activated by decreased blood pressure or low sodium levels.

ADH's main mechanism of action lies in increasing water permeability in the collecting ducts of the kidneys, which leads to decreased urine production and therefore conservation of body water. Aldosterone acts mainly on the renal tubules, encouraging them to reabsorb sodium and excrete potassium, indirectly influencing water retention due to osmotic forces.

It's critical to note that both ADH and aldosterone are part of larger physiological systems and networks, working synergistically to maintain homeostasis in the body. While ADH is chiefly concerned with water reabsorption, aldosterone is focused on maintaining sodium-potassium balance, with both affecting blood pressure and volume in different but interconnected ways.

ADH vs. Aldosterone Comparison Chart
ADH vs. Aldosterone Definitions
◉ADH
ADH is synthesized in the hypothalamus and stored in the pituitary.
The hypothalamus creates ADH in response to dehydration.

◉Aldosterone
Aldosterone helps in maintaining sodium and potassium balance.
Aldosterone prompts the kidneys to reabsorb sodium effectively.

◉ADH
ADH increases water permeability in kidney ducts.
Due to ADH, the kidney ducts reabsorb more water back into the bloodstream.

◉Aldosterone
Aldosterone is produced in the adrenal cortex.
The adrenal cortex diligently secretes aldosterone to manage electrolytes.

◉ADH
ADH is a hormone that regulates water balance.
When you're dehydrated, ADH secretion increases.

◉Aldosterone
Aldosterone plays a pivotal role in regulating blood pressure.
High levels of aldosterone can lead to hypertension.

◉ADH
ADH helps to concentrate urine during water scarcity.
The desert animals have high ADH levels to conserve water.

◉Aldosterone
Aldosterone secretion is controlled by the renin-angiotensin system.
A decrease in blood pressure activates aldosterone release via the renin-angiotensin system.

◉ADH
ADH plays a role in maintaining blood pressure.
Elevated ADH can constrict blood vessels, raising blood pressure.

◉Aldosterone
Aldosterone influences fluid volume within the body.
When aldosterone levels rise, you may notice increased fluid retention.

◉ADH
hormone secreted by the posterior pituitary gland (trade name Pitressin) and also by nerve endings in the hypothalamus; affects blood pressure by stimulating capillary muscles and reduces urine flow by affecting reabsorption of water by kidney tubules

◉Aldosterone
A steroid hormone that is produced by the adrenal cortex and regulates salt balance, blood volume, and blood pressure in the body.

◉Aldosterone
(steroid hormone) A mineralocorticoid hormone, secreted by the adrenal cortex, that regulates the balance of sodium and potassium in the body.

◉Aldosterone
a corticosteroid hormone that is secreted by the cortex of the adrenal gland; regulates salt (sodium and potassium) and water balance
