You Wanna Know the Reasons Why Beer Makes You Pee!

There are 3 main reasons why you run to the bathroom quite often after a party night. No need to worry. It’s all a normal process and most drinking individuals face it at least once in their lives. Let’s take a look…

Beer is a Diuretic

Even though beer is mostly water than alcohol yet, even the slightest amount of alcohol in beer (4%-5%) can affect your body. Alcohol affects your vasopressin (your antidiuretic hormone) which is responsible for retaining the necessary water required by the body. 

Due to heavy drinking, alcohol enters your bloodstream and starts messing up your kidney and bladder functions. Instead of retaining water, the kidneys push it straight to the bladder. 

Now what…

It’s time to head to the washroom. You start acting restless. Your friends suggest you not to go to the restroom, or you’ll “BREAK THE SEAL,” which is just a myth for first-time drinkers. In reality, there is no physical seal inside our bodies. It’s just a way to say that you’ll be visiting the washroom again and again for a few hours because you have consumed excessive alcohol.

All alcoholic beverages, including wine, beer, and hard liquors, are diuretics. So, if you are planning to consume a pack of 6 beers, be prepared because you might end up wetting your pants.

Beer is mostly Liquid

Beer is made of grains, yeast, hops, and water. However, water is the dominant ingredient making up the majority of beer’s volume. With 96% water in beer, your bladder gets full after 1-2 cans.

Any liquid you drink, whether it’s beer, wine, a refreshing cocktail, or a simple plain juice, the water present in these drinks finds a way to leave your system through urine. Your body takes in the water it needs and passes out the remaining.

After drinking beer, you may feel the urge to empty your tank frequently. As a result, you may find a clear-looking pee. But don’t be too happy about it…loss of extra fluids will make you dehydrated and cause hangovers the next morning.

For a habitual drinker, urine output may be less because the body is accustomed to the presence of alcohol and adjusts accordingly. Therefore habitual drinkers will feel less urge to urinate in comparison with first-time drinkers.

On average, your pear-sized bladder can hold up to 300-400 ml (13.5-20 oz) of urine. With beer being a diuretic, it inhibits the production of vasopressin and increases urine output. As a result, you end up losing 320 ml of urine after downing 200 ml of beer.

How Long After Drinking Beer Do You Pee?

It kinda varies from person to person. For 1 standard drink (12 oz beer), it takes 1 hour to metabolize it completely. So, after drinking a can or two, you might need to empty your tank after 60-120 minutes. If you’re drinking whiskey, gin, or any other high-ABV spirits, you may notice an increase in urine production as compared to a light beer.
