Why urinary tract infections come back — and how to lower the risk

Urinary tract infections are common, and for many women they return. Understanding why can help you take simple steps to protect yourself.

A urinary tract infection (UTI) happens when bacteria — most often Escherichia coli — enter the urinary tract and multiply. Women are more likely to get UTIs, and many experience them more than once.

Why they recur

Bacteria can attach firmly to the lining of the urinary tract. Repeated courses of antibiotics can also disturb the natural balance of healthy bacteria, which may make recurrence more likely.

How cranberry may help

Cranberries contain proanthocyanidins (PACs), which research suggests can make it harder for E. coli to stick to the cells lining the urinary tract.

Simple prevention habits

Drink plenty of water, don't delay going to the toilet, wipe from front to back, and pass urine after intercourse.

When to see a doctor

Seek medical care promptly if you have fever, pain in your back or side, blood in your urine, or if symptoms don't improve. These can be signs of a more serious infection.
