Why drinking caffeine and ethyl alcohol both tend to dilute urine and increase urinary volume ?


maybe anatgonizing ADH activity?????


Alcohol inhibits release of ADH from post.pituitary causing enhanced diuresis,this effect is also supplemente by alcohol induced release of ANP.....however tolerance develops and this increase urine output subsides after a certain period of time.

Upon withdrawal there is increased release of vasopressin from post.pituiitary and consequent retention of water....may cause diluitional hyponatremia .


coffain acts by dilating afferent arterioles and binding to ADH. :roll:
