It is a usual thing for people to hold in their pee. Holding in of pee is mainly due to the chances of one being caught up in what they are doing at that particular moment or even lack of bathroom insight.
Peeing is important as it allows one to get rid of excess water and waste product present in the body. The urine is mainly stored in the bladder before one gets the chance of letting it out.
One of the main things to note about holding of pee is that each and everybody has their average time in which they can hold in their pee. Some can stay for longer hours, while others can only hold for a short time.
Secondly, holding in of pee results in stretching of the bladder. The good thing about the bladder is that they are elastic and they can always stretch to hold more than 1-2 cups of urine.
Depending on how often you own in your pee, the bladder gets used to the situation, and it finally ends up holding more.
Finally, holding of pee for long can lead to some leaking. It is always not a good thing holding in your urine for long as it might start leaking little by little.
Hence, whenever you have a chance of helping yourself, it is better to do so as soon as possible.
