Factors influencing how long does a UTI last without antibiotics

The duration of a UTI without antibiotics can vary significantly from person to person. 

In some cases, a UTI may naturally resolve within a few days without any medical intervention.

While in others, the infection may remain or even worsen over time. 

It is important to note that there is no fixed or predetermined duration for a UTI to last when antibiotics are not used.

A study published in The National Library of Medicine tried to see what happens to people with UTIs if they don’t take antibiotics.

Researchers found that some people do get better on their own, especially within the first 9 days.

But for some women, the infection gets even worse over time.

That is why it is vital to ask a doctor if you have UTI because antibiotics are usually the best way to treat it.

There are several factors that influence how long a UTI can last without antibiotics.

It includes the following:


The severity of the infection can contribute to its duration. 

A mild UTI may resolve without antibiotics.

While a more severe infection might stay longer and need antibiotics for its treatment.

Immune system

Your body’s ability to fight the infection naturally plays a significant role. 

A strong immune system may help you to get away from the infection more quickly.

Lifestyle habits

It also depends on certain lifestyle habits on how long can a UTI last.

By taking a few preventive steps, some mild symptoms of UTI, like a constant need to urinate and painful urination, can go away on their own. 

These preventive steps include:

  • Practicing good hygiene
  • Drinking adequate water
  • Urinating regularly and completely
  • Wearing breathable underwear

Eating spicy foods may exacerbate the symptoms of UTIs and may increase their duration to last.
