ADH vs. Aldosterone: What's the Difference?
Edited by Sumera Saeed || By Sawaira Riaz || Published on October 12, 2023
ADH (antidiuretic hormone) regulates water reabsorption in kidneys; Aldosterone controls sodium and potassium balance.
Key Differences
ADH, also known as vasopressin, and Aldosterone are both hormones that play crucial roles in the body's fluid and electrolyte balance. However, their primary functions and modes of action differ significantly.

ADH primarily influences the amount of water reabsorbed by the kidneys, helping regulate the body's overall water balance. When ADH levels rise, more water is reabsorbed, concentrating the urine and maintaining hydration.

Aldosterone, on the other hand, chiefly affects the reabsorption of sodium and the excretion of potassium in the kidneys. This not only regulates electrolyte balance but also indirectly affects water retention, since where sodium goes, water often follows.

ADH's secretion is primarily triggered by increased blood osmolarity or low blood volume, signaling the body to conserve water. In contrast, Aldosterone is mainly secreted in response to low blood sodium or high blood potassium levels.

In essence, while both ADH and Aldosterone are pivotal for maintaining the body's fluid and electrolyte homeostasis, ADH focuses on water conservation, whereas Aldosterone emphasizes sodium-potassium balance.

ADH and Aldosterone Definitions
ADH
ADH acts on the kidneys' collecting ducts.
In response to ADH, kidneys reabsorb more water back into the bloodstream.

Aldosterone
Aldosterone plays a role in maintaining blood volume and pressure.
By influencing sodium retention, Aldosterone can indirectly affect blood volume and pressure.

ADH
ADH is a hormone that promotes water retention in the body.
High levels of ADH lead to decreased urine production.

Aldosterone
Aldosterone affects sodium and potassium levels in urine.
High Aldosterone levels promote sodium reabsorption and potassium excretion.

ADH
ADH is released by the posterior pituitary gland.
The synthesis and release of ADH occur in the brain.

Aldosterone
Aldosterone is produced in the adrenal cortex.
The adrenal glands, located above the kidneys, produce Aldosterone.

ADH
ADH plays a role in osmoregulation.
ADH secretion increases when blood becomes too concentrated.

Aldosterone
Aldosterone's release is influenced by the renin-angiotensin system.
Low blood pressure can trigger the renin-angiotensin system, leading to Aldosterone secretion.

ADH
ADH's levels can influence blood pressure.
Elevated ADH can lead to increased blood pressure due to water retention.

Aldosterone
Aldosterone is a steroid hormone that regulates electrolytes.
Aldosterone helps maintain sodium and potassium balance in the body.

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
