Do Some People Actually Have Small Bladders?

We’ve all been there — on a road trip, in a long meeting, or stuck in traffic — you need to go. Now. 

If you seem to be always searching for the nearest restroom, you may wonder if you have a small bladder.

In this blog, our experts at Golden Gate Urology in Berkeley, California, take a closer look at what affects how often you need to go, and whether some people are born with smaller-than-average bladders.

What’s a ‘normal’ bladder size?

A healthy adult bladder can typically hold 400-500 milliliters of urine (some men can hold up to 700). That’s roughly 13-16 ounces, or about the size of a standard water bottle.

Most people start to feel the urge to pee when their bladder is about half full, and the sensation intensifies as more urine builds up.

How often is too often?

Most people urinate 6-8 times a day, depending on how much they drink. If you go more than that, if you urinate more than twice at night, and/or your bathroom habits interrupt your life, it’s worth chatting with one of our specialists.

Frequent urination could indicate something more than just a “small bladder.” It could point to an overactive bladder, a UTI, diabetes, or another condition that deserves attention.

Do some people have smaller-than-normal bladders?

Yes, but it’s not common. While there’s some variation in bladder capacity from person to person, most healthy bladders fall within the same general size range. If you feel like yours is small, it may be because of function, not size.

Your frequent need to urinate typically boils down to sensation and control (or a lack thereof). You might feel the need to go sooner or more frequently due to how your bladder communicates with your brain or how it reacts to certain triggers.

Reasons your bladder feels small

Okay, so you probably don’t have a tiny bladder, but you still need to go a lot. What gives? Here are a few common culprits. 

Overactive bladder (OAB)

This condition causes sudden, intense urges to urinate, even if your bladder isn’t full. It can lead to frequent trips to the bathroom day and night.

Interstitial cystitis

This chronic condition causes pain and pressure in your bladder, which can make you feel the urge to urinate, even when your bladder isn’t full. 

Enlarged prostate

An enlarged prostate can put significant pressure on your urinary system and cause frequent urination. The same goes for prostate tumors.

Urinary tract infections (UTIs)

A UTI can irritate the bladder lining and make you feel like you need to pee constantly, even when there’s little urine present.

Fluid and caffeine intake

Drinking a lot of fluids can ramp up your need to urinate, especially alcoholic and caffeinated drinks, which irritate the bladder.

Pelvic floor dysfunction

If your pelvic muscles aren’t working well, your bladder may not empty fully, leading to more frequent urges. That’s especially common in postpartum and menopausal women.

Diabetes

Diabetes doesn’t come with many warning signs, but increased urination is one. High blood sugar levels impair the kidneys’ ability to reabsorb glucose from the urine, resulting in more glucose in the urine and increased urine volume.

What can you do about it?

The good news? You can retrain your bladder and improve control.

One of the first things we recommend is making lifestyle adjustments. Cutting back on caffeine, alcohol, and late-night fluids can help reduce urgency and frequency.

Your Golden Gate Urology provider can prescribe medications and hormone therapies to help calm the bladder, especially if your symptoms stem from OAB or another medical condition.

We can also discuss bladder training and pelvic floor exercises (aka Kegels). Bladder training involves gradually increasing the time between bathroom trips to help your bladder learn to hold more. Pelvic floor exercises strengthen the muscles that support bladder control.
