Does caffeine make you pee more?

Does caffeine make you pee more?

Does caffeine make you pee more? There is sort of a debate going on as to whether caffeine makes you urinate too much or not.

Some people say caffeine is a diuretic that makes you go to the bathroom too much and become hydrated. Others say the water in coffee and tea can even help to hydrate you, not dehydrate you.

But if you have six cups of coffee in one morning, obviously you are getting so much fluid that you are going to have to go to the bathroom more.

Also, some studies have found that if you take a large amount of caffeine even in non-beverage form it can make you urinate more.

Similarly, even a moderate amount of caffeine can make a person who is not used to caffeine urinate excessively.

The research

An article at WebMD.com that has been taken down stated about the research:

Some research has shown that caffeine intake can also affect our fluid balance. In one study, 12 caffeine consumers were told to abstain from caffeine for five days and were then given 642 mg of caffeine in the form of coffee. Their urine output increased when given the caffeine. Another study done on eight men tested the effect of 45 mg, 90 mg, 180 mg, or 360 mg of caffeine on urine volume. An increase in urine volume was seen only at the 360 mg dose of caffeine. One limitation to these studies is that they did not evaluate the impact of caffeine when consumed on a regular basis. A onetime dose may affect the body differently than daily consumption.

Back in 1928, caffeine was shown to have no significant impact on urinary output. Subsequent studies have shown that caffeine-containing beverages did not impact urinary output any differently than other beverages. Based on this, the Institute of Medicine recommends that ‘unless additional evidence becomes available indicating cumulative total water deficits in individuals with habitual intakes of significant amounts of caffeine, caffeinated beverages appear to contribute to the daily total water intake similar to that contributed by noncaffeinated beverages.’

Hydrate by drinking caffeinated beverages

In other words, you can actually hydrate yourself by drinking coffee, tea or soda, though plain water is still recommended as the best way to get your daily fluids.

But WebMD says caffeine can increase the need to pee. It can depend on how much caffeine you take, your tolerance for it and the type of food, drink or medicine you get it in. And if you have urinary incontinence or have frequent urges to urinate, it may increase after drinking a caffeinated beverage.

One good way to avoid excessive urination from drinking copious amounts of coffee or soda is to take Viter Energy Mints with caffeine [1].

The video answers whether coffee and caffeine make you pee more (answer: maybe).

Viter Energy Mints, available in our shop [2], are sugar-free, and the mintiness freshens your breath, which is handy if you are somewhere without a toothbrush. The mints also contain invigorating B vitamins and are made with wholesome ingredients.

Facts and myths

Caffeine Informer, a site that features many articles about the facts and myths surrounding caffeine, has an article titled Caffeine and Hydration: What the Research Says[3].

This article too cites the study that said caffeine can act as a diuretic that promotes urination, but only in doses of 360 mg or more and the second study that found that if you have built up a tolerance, the effect is less noticeable.

Those who have little to no tolerance built up to caffeine may experience significant diuretic effects. (There are references to these studies in the Caffeine Informer article.)

"Yet another study found that consuming caffeine prior to exercise negated the diuretic effect of caffeine as compared to consuming caffeine and then resting," Caffeine Informer writes.

Caffeine vs. taurine

But Caffeine Informer cited another study that considered energy-drink consumption and how caffeine vs. taurine affected hydration. The study found that the subjects who drank caffeinated energy drink urinated a lot more than the group that got just taurine in the drinks. They were already dehydrated, too.

"Therefore, based on the research, caffeine is a diuretic but not a very efficient one since there are several factors that determine how well it actually works in this capacity," the article states.

The article asks, Then why does coffee make me have to pee?

There are possibly a couple of reasons for this. Firstly, if you are already in a hydrated state any additional fluids will cause increased urine production. So, a 12-16 fl oz (355-500 ml) coffee will produce about the same amount of urine output.

Secondly, if you aren't a regular coffee or caffeine consumer then large amounts of caffeine does have a diuretic or dehydrating effect, thus increasing urine volume.

Lastly, caffeine can cause incontinence in some men and women. This causes the urge to urinate even if the bladder isn't yet full.

Does caffeine make you pee more?

In an article [4] exploring whether caffeine causes dehydration,

LiveScience.com asked Lawrence Armstrong of the Department of Kinesiology at the University of Connecticut and the director of the Human Performance Laboratory whether caffeine dehydrates people. He said:

'˜The truth of the matter is, a small increase in urine output has little to do with dehydrating the body. If you drink a liter of water, [urination] will increase. Doesn't mean you shouldn't drink water.
 

˜The fact that we don't have hospital emergency rooms filled [with patients] because they [drank] caffeinated beverages is clear evidence ... If there were negative health effects, [they] certainly would have been identified.'

University of Connecticut researcher and author of a study on diuresis and caffeine Sophie Killer told National Public Radio: "It's well understood that if you drink coffee habitually you can develop a tolerance to the potential diuretic effects of coffee."

By the way, that NPR article says [5]: "Bottom line: A daily coffee habit won't lead to dehydration. But it's best to limit caffeine to moderate levels to steer clear of jitters and interruptions to sleep."

No fluid loss, but you might pee more

Mayo Clinic lays out the facts on caffeine and peeing:

Drinking caffeine-containing beverages as part of a normal lifestyle doesn't cause fluid loss in excess of the volume ingested. While caffeinated drinks may have a mild diuretic effect — meaning that they may cause the need to urinate — they don't appear to increase the risk of dehydration.

As our blog stated [6]:

The idea that caffeine intake causes dehydration can be traced back to a 1928 study. It noted increased urination in people who drank beverages with caffeine in them.

But drinking any beverage in larger volumes, with or without caffeine, causes you to urinate more. And this includes water itself.

So go ahead and enjoy your caffeinated beverage, chocolate, mints, kola nuts or medicine. But if you haven't built up a tolerance for caffeine, expect to urinate more. And if you have more than 360 mg, expect to pee more even if you have built up a tolerance.

Does caffeine help with ED?
Can caffeine help with ED?

by Mark Miller 3 min read

Erectile dysfunction. In combination, those are two of the ugliest words known to man. But can caffeine help you get it up?

Science hasn't found the definitive answer to this question, but one study concluded that fewer men who consume caffeine have problems performing. The study said:

Caffeine intake reduced the odds of prevalent ED, especially an intake equivalent to approximately 2-3 daily cups of coffee (170-375 mg/day). This reduction was also observed among overweight/obese and hypertensive, but not among diabetic men. Yet, these associations are warranted to be investigated in prospective studies

Breastfeeding and caffeine
Caffeine while breastfeeding? Go ahead, it's OK

by Mark Miller 4 min read

Many breastfeeding mothers wonder if it's OK to take caffeine. In fact, many nursing mothers just avoid caffeine in case it would keep their babies fussy, jittery and awake.

The answer is yes, you can take caffeine while breastfeeding, as long as you don't go over about 300 mg a day.

It's an important question because caffeine is in so many products, and taking coffee, tea, or soda is such a common ritual.

And breastfeeding mothers may be tempted to take caffeinated products because they are deprived of sleep by their newborns' odd sleep schedule.
