A Question regarding urine output

[twolzy2p_42]

Assuming I were to drink these using the same volume. Which would make me pee more and why.

1. Orange Juice

2. Milk

3. Beer

4. Water

5. Gatorade

I'm going to say the beer because it has a diuretic effect.

[Imafloat, BSN, RN]

I think it is beer because alcohol supresses ADH. ADH 'punches' holes in the tubule, allowing fluids to be reabsorbed. With less ADH more of the fluid you drink is lost in urine.

Does gatorade have caffiene? If so, it may stimulate the bladder/kidneys and cause more output? Otherwise, the berr is my guess.

Hi, twolzy2p_42!

ADH, antidiuretic hormone, regulates the water in our bodies. It is able to act on the kidneys to partially cause them to hold or release water. When ADH production is decreased, or somehow interrupted, urinary output of water is increased. Drinking something high in electrolytes or salt will cause the blood plasma osmolality to rise so that ADH production will increase causing water retention. So, ingestion of your Gatorade is going to make you pee less by having the opposite effect of helping you to retain water. The ingestion of alcohol decreases the secretion of ADH and shuts off the ability of the kidney to retain water resulting in the patient diuresing. This is why drinkers are constantly having to visit the bathroom. The answer to your question is #3, the beer.

That's why I've always said that you don't buy beer.........you RENT it.

I agree Beer is the correct answer to explain some of the mechanisms in more detail Adenosine physiologically constricts the afferent renal artery, meaning it will derease the renal flow rate which decreases urine synthesis, stimulates renine release, increasing Angio tension II, increasing aldosterone, and thus stimulating the production of more ADH. Because alcohol is a an inhibitor of adenosine meaning it blocks adenosine receptors renine would not be secreted by the kidneys without renine angiotensinogen cannot be converted to angiotension I which is ultimately converted to angiotension II. Without the presence of this precursor the kidneys would not be stimulated to secrete aldosterone or vasopressin (ADH) More simplistically, low renine, low angiotension II, low ADH, more Urine.

to clarify how the kidney shuts off the ability to retain water which was introduced in another post is because angiotension II which produces ADH also stimulates the zona glomerolosa of the adrenal cortex to synthesize and secrete aldosterone, which was stated previously. Aldosterone increases Na reabsorption. Reabsorbing Na is necessary in order to reabsorb Glucose, Amino Acids, Cl-, and lastly water due to the hypotonicity of the lumen in the renal tubule system once these other solutes have already been reabsorbed into the bloodstream. Since aldosterone is not secreted followed all the way back to the blocked adenosine receptors Na is not being reabsorbed if Na is not being reabsorbed water is not being reabsorbed into the blood stream so water along with Na and the other solutes continue further through the renal tubule system to be excreted from the body.

I must admit I am not a nurse just a student in PA school who happens to be taking physiology currently and thought I could add further detail to the discussion.

It doesn't have caffeine to my knowledge, but lots of sodium and potassium. I know when I drink gatorade I have to pee like no other... but same with beer (for reasons discussed), and also orange juice (I blame the vitamin C).

I'd go along with beer to the question posted in the first post, tho.
