How Long Does It Take To Pee After Drinking Water (And Why)?

Exact Answer: 9 To 10 Hours When The Urinary Bladder Is Empty

Depending on how much one drinks, it can take a while to pee, but the average person pees 1-2 times per day. 

Normally, if the urinary bladder is full, it only takes 10 to 15 minutes to pee after drinking one glass of water. However, if the urinary bladder is empty, it may take 9 to 10 hours to pee after drinking water.

Overall, liquid intake depends on how long one gets to pee. It is also important to note that drinking water for proper body hydration is necessary.

The amount of time it takes to pee after drinking water will vary depending on age, gender, how much water was consumed, etc. 

A study found that when one drinks less than 600ml in an hour or more than 1500ml in one hour, there is no difference in how long it takes to urinate. 

It can take up to two hours for urine production rates to return to normal after excessively heavy consumption of fluids, resulting in urinary tract infection or kidney failure. If the pee is yellow, this may be a symptom of a urinary tract infection, and one should consult a medical professional.

Overall, it takes about 15 minutes to urinate after drinking water if the urinary bladder is already full. If the urinary bladder is empty, it might take 9 to 10 hours.

Patients are instructed to drink plenty of fluids, especially after being put on diuretic medications with a dehydrating effect. When too little fluid enters the body, the kidneys will concentrate urine excessively to conserve water. 

Hence the need for more frequent trips to the bathroom on doses of diuretics which can otherwise lead to a dangerous loss of fluids through respiration and perspiration. 

A key thing is how much one is drinking concurrently with medications. If one is not taking enough liquid with it, they should take some at intervals to not interrupt the dose with an urgency later if needed because of dehydration.

Why Would Peeing After Drinking Water Take So Long?

Some people might take longer peeing after drinking water because of how the body’s kidneys can filter and retain fluids. Drinking too much water too quickly puts the body in a state of diuresis or extreme urination.

Trying to flush excess water in the bladder is one of water’s many functions in our bodies. Drinking lots of fluids causes the kidneys to try harder, and they are more likely to overshoot when they decide how much liquid should be living in the bladder. 

The body also holds onto liquid because it’s nervous about not having enough–in other words, for insurance purposes. 

Some people might have a medical condition that prevents their kidneys from operating normally, but there’s nothing wrong with them.

Some people have a harder time excreting urine normally. People with interstitial cystitis have sensations of having to pee, but their bladder doesn’t contract fully, so they can’t get all the urine out. 

It may take longer for these individuals to expel the water because there is more water in the body to urinate out. This persists until they feel full and drink less fluid or exercise – then it’s easier for them to go. 

A person also might not be able to completely void all of the contents of their bladder because they are constipated or irritated by other things in their diet that are causing hemorrhoids.

There are a few potential reasons, including that drinking an excessive amount of water too quickly will not allow proper absorption of fluids into the bloodstream.


The kidney normally produces 800 to 200 ml of urine per day if the water intake is about 1 liter per day. It takes 9 to 10 hours for the body to produce 2 cups of urine. The length of time for each individual depends on their body, age, and water consumption.

If a person is dehydrated, it may take 1 or two hours to urinate. Unhealthy individuals who have kidney issues might urinate more than those with normal kidney functions. 

People with diabetes will urinate quickly after drinking one glass of water, and other conditions include alcoholism, diuretic intake, bladder stones, and more.
