Urinary tract infections (UTIs) are a common complication of MS, and they pose unique risks to people with MS. That's because infections can be a trigger for MS symptoms. So if you’re living with MS, it’s important to understand and recognize the signs of a potential UTI.

Here’s how to spot the symptoms, plus what to know about treatment and prevention.

Why Are UTIs Common in MS?

At least 80% of people with MS will experience bladder problems. MS-related inflammation, scarring, and nerve damage in the brain or spinal cord can interfere with the normal transmission of signals between the brain and the urinary system. This can lead the bladder to have trouble storing and emptying urine, which can lead to UTIs.
