This information tells you how long you can hold your urine

Our healthy bladder can hold about 500 - 600 ml of urine which is considered full and creates a feeling of needing to urinate. The bladder is an elastic organ whose volume is not constant. In men, the amount of urine in the range of 200-300ml can produce the feeling of urinating while in women from 250-350ml. However, depending on the size of the person, the bladder can hold as much as 900 to 1500 ml. It takes your body 9 to 10 hours to make about 400 - 500ml of urine. That's the amount of time you can stay in and remain in a safe zone where holding your pee isn't likely to damage your organs.

Your bladder is a stretchable organ. The process of emptying your bladder is not like a simple contraction of the bladder muscles but a combination of the abdominal muscles. Two urinary tubes called ureters carry filtered urine from the kidneys into the bladder. When your bladder holds 500 – 700 ml of urine, it is considered full.
Research tells us that the bladder has a direct line of communication with the brain. The bladder is filled with receptors that tell the brain how full the bladder is.
Basically, there is an invisible limit in your bladder. When your urine reaches that point, your brain gets a signal that you need to pee. This happens when your bladder is only a quarter full.
When you first feel the urge to urinate, your bladder probably has quite a bit of time to urinate before it is completely full. And when your bladder is full, the surrounding muscles contract to keep urine from leaking out until you're ready to empty it.

As mentioned above, the bladder in an adult takes 8-9 hours to fill, so this is a safe period for you to hold your urine under certain circumstances. urinate. This time period may change if you add more water or reduce your water intake.
Complications and other health problems with your bladder can lead to conditions like urinary incontinence, overactive bladder, and urinary retention. These conditions are more common when you are over 50 years old.

Normal frequency of urination varies greatly from person to person. It also depends on how much fluid you drink each day.
Babies and children have a smaller bladder volume, so they need to empty their urine more often. Newborns typically urinate between six and eight diapers a day, but can urinate more than that.
Toddlers seem to like going more, especially during toilet training, maybe more than 10 times a day.
When you're an adult, peeing six to seven times a day is considered average. Going at least 4 times and at most 10 times is still within the range that is considered normal.

Some medications, such as diuretics for high blood pressure, can make you need to urinate more often. Medical conditions, such as diabetes, pregnancy, and sickle cell anemia, can also cause you to urinate more often.
3.1. Dehydration If you don't feel the need to urinate for a while, you may be dehydrated. Dehydration occurs when your body loses more fluid than it absorbs. When you lose too much fluid, your body's functions are affected. Symptoms of dehydration may include:
Dizziness Frequent urination Brown or dark yellow urine Dry mouth 3.2. Problems that can affect your ability to urinate Sometimes you may want to urinate, but you have trouble doing so. Several conditions can affect your ability to urinate. These conditions include:
Kidney failure Urinary tract infection Prostate enlargement Problems with bladder control, such as urinary incontinence, overactive bladder, interstitial cystitis Obstruction a blockage that prevents bladder emptying (urinary retention) If you have trouble urinating, you should see your doctor. This is not a symptom you should try to learn to live with.
If your bladder function is compromised in any way, it could be a symptom of another underlying health problem. Don't wait too long for difficulty urinating to resolve. After 36 to 48 hours of symptoms, it's time to seek a professional diagnosis.

For young children, it can be difficult to know when your child has difficulty urinating. Especially during infancy or toddlerhood, your child may not be able to communicate with you about what is going on in their body. Your pediatrician will likely ask you to count the number of wet diapers your baby produces each day. If you count fewer than 4 wet diapers a day, call your pediatrician. Pay attention to the color of the urine in your child's diaper. It should be clear to pale yellow in color. Urine that is dark amber or darker may indicate dehydration. Pay particular attention to dehydration for babies and toddlers during the summer months.

The dangers of fasting are mostly cumulative. Holding your pee for six hours during that memorable trip probably won't hurt you in the long run.
But if you regularly ignore the urge to pee, you may experience these complications. In general, you should go when you feel the need to go!
Here are some of the dangers of holding in urine:
If you don't empty your bladder often enough or don't empty it all in a few days, it can lead to a urinary tract infection (UTI). If you hold your urine out of habit, your bladder may begin to atrophy. Over time, you may develop urinary incontinence. When you hold your urine for 10 hours or more, you may experience urinary retention, which means the muscles in your bladder can't relax and won't let you urinate on your own, even if you wanted to. In rare cases, holding in urine can cause the bladder to burst.

The chances of you dying from holding your pee are very, very low. Some doctors may even say it doesn't exist. In general, your bladder will empty on its own long before you're in physical danger.
In rare cases, a person may hold in urine for so long that they eventually cannot urinate on their own because the bladder muscles are too stretched and unable to contract. This can lead to bladder rupture. If your bladder ruptures, you will need immediate medical attention. A ruptured bladder is a life-threatening condition.
When you hold your urine for days, you are exposing your body to harmful bacteria (bacteria that should have been excreted). This can lead to a UTI, which can escalate to all sorts of complications, including sepsis.
Most people can hold their urine occasionally for a few hours and it's okay.
Holding urine can feel like an emergency. But you'll have peace of mind knowing that it's very rare to die from complications from holding your urine. As a general rule, empty your bladder whenever you feel the urge. Leave it completely blank each time you go and try not to rush it.
There are a number of medical conditions that can make urinating painful, uncomfortable or even impossible. If you have trouble urinating, you should see your doctor within a day or two of the onset of symptoms.
