It is impossible to hold your urine for 100 days, and it is harmful to your body to hold it for long periods of time.
A normal person urinates about four to six times a day during the day and zero to one time at night. Usually the normal amount of urine in a day is about 1500-2000ml.
And too little urine may be caused by hot weather, too much water evaporation or less hydration, insufficient rehydration and so on. It may also be caused by kidney stones, ureter stones or tumors, etc., resulting in urine not being able to be discharged and staying in the body.
Holding back urine for a long time not only causes great damage to the bladder, but also contains many bacteria in the urine, which can lead to cystitis or ureteral inflammation or pyelonephritis.
If you have symptoms of abnormal urine output, it is recommended that you seek medical attention in a timely manner and under the guidance of your doctor for targeted treatment. Avoid holding your urine as much as possible in your daily life.
