What are Bladder Norms?

January 25, 2023

Patients coming to pelvic health physical therapy often have abnormalities with the bladder or bowel habits. And often, if these habits have been around for a while, it is difficult for someone to know what is normal. So what is a ‘normal’ bladder like?


-Voids aka peeing, should occur 5-8 times in 24 hours. That equates to voiding every 3-4 hours during the day

-Nighttime voiding should occur 0-1x per night, or 1-2x per night for those over 60 years old


-The average amount voided is about 200-250ml or 6-8 ounces

-Post-residual volume, aka the amount left in your bladder after a void should not exceed 50ml


-Maximum bladder capacity is 450-550ml or about 15-19 ounces

-The first sensation of fullness occurs at 100-250ml or about 3-8 ounces

-The typical desire to void occurs at 200-300ml or 6-10 ounces

-A strong urge to void occurs at 350-550ml or 11-18 ounces


-There should be no hesitation or difficulty initiating a stream

-A void should take about 8-12 seconds (increased age in men can lead to a natural slowing of stream and thus increase time to void)

Medications and medical diagnoses can sometimes lead to deviations from these norms. However, sometimes deviations from these norms can indicate a musculoskeletal or neuromuscular dysfunction at the pelvic floor. Seeing a pelvic health physical therapist can help return you back to these ‘norms’.
