ADH Full Form: Antidiuretic Hormone
Overview:
– Antidiuretic Hormone (ADH), also known as vasopressin, is a crucial hormone produced by the hypothalamus and stored in the posterior pituitary gland.
Functions of ADH:
– Water Retention: Increases water reabsorption in the kidneys, reducing urine output.
– Blood Pressure Regulation: Constricts blood vessels, which can elevate blood pressure.
– Osmoregulation: Helps maintain the body’s water balance by responding to changes in blood osmolarity.
Importance of ADH:
– Hydration: Helps the body retain water, which is vital for overall hydration and cellular function.
– Homeostasis: Plays a key role in maintaining fluid balance and electrolyte levels in the body.
Conditions Related to ADH:
– Diabetes Insipidus: A condition characterized by insufficient ADH, leading to excessive urination and thirst.
– Syndrome of Inappropriate Antidiuretic Hormone (SIADH): A condition where excess ADH is secreted, causing water retention and dilution of blood sodium levels.
Conclusion:
Understanding the role and functions of Antidiuretic Hormone (ADH) is essential for grasping how the body regulates water balance and maintains homeostasis.
