Can a UTI Go Away on Its Own?

A urinary tract infection (UTI) causes burning, urgency, and frequent bathroom trips. While you may hope it will clear up on its own, most UTIs need treatment. Here's what the research says about whether a UTI can go away without antibiotics.

Can a UTI Resolve Without Antibiotics?

Some uncomplicated UTIs can clear up on their own. Studies show that 25-42% of women with mild UTIs become symptom-free within one week without antibiotics. However, this means more than half of untreated UTIs don't resolve naturally.

Without treatment, UTI symptoms typically last about 5 days. With antibiotics, symptoms often improve within 3 days. So while waiting it out is possible for mild cases, treatment gets you feeling better faster.

How Long Does a UTI Last?

An untreated UTI can last from a few days to several weeks. In mild cases, you might feel discomfort for 1-2 weeks. But without treatment, the infection can persist or spread to your kidneys, causing a more serious condition called pyelonephritis.

Risks of Not Treating a UTI

Ignoring a UTI can lead to serious problems. The infection can travel from your bladder to your kidneys. In rare cases, this can cause sepsis, a life-threatening blood infection. Kidney infections require stronger antibiotics and sometimes hospitalization.

How to Get Rid of a UTI

The most effective way to get rid of a UTI is with antibiotics. A typical course lasts 3-5 days for uncomplicated infections. While waiting for treatment or alongside antibiotics, drink plenty of water to help flush bacteria from your urinary tract.

Some people try cranberry products, though research on their effectiveness is mixed. Pain relievers can help manage discomfort while your body fights the infection.

When to See a Doctor

See a healthcare provider if you have UTI symptoms like burning with urination, frequent urge to pee, or cloudy urine. Get immediate care if you develop fever, back pain, nausea, or vomiting, as these may signal a kidney infection. Pregnant women, people with diabetes, and those with weakened immune systems should always seek treatment for UTI symptoms.
