As we are all aware, if you drink a large quantity of water in a short time period, you will likely have to go to the toilet not too long afterwards.
The body detects the increase in fluid volume (or more precisely in this instance the decrease in sodium concentration) and kicks off the renin-angiotensin-aldosterone pathway.
This ultimately results in a decrease in anti-diuretic hormone (ADH) which in turn decreases water absorption from the collecting ducts and distal convoluted tubule in the kidney.
So my question is, if we rapidly consume a large volume of water in a very short period of time, could the resulting decrease in ADH hormone overshoot the mark and result in the body eliminating more water than what is ideal.
That is, could drinking a large amount of water in a short time actually have a dehydrating effect?
