While it is possible for a UTI to resolve on its own in a healthy individual with a healthy immune system, it is often advisable to seek medical attention. Untreated UTIs can lead to more severe complications, such as ascending infections involving the kidneys. Antibiotic therapy is typically recommended to alleviate symptoms and prevent further progression of the infection.
No, UTIs are not contagious.
The duration of a UTI can vary depending on whether it is treated. With appropriate antibiotic therapy, symptoms should generally improve within 48 hours.
