What science reveals about urinary tract infections (UTIs) | By Sampath Management | November 2025

Urinary tract infections (UTIs) are among the most common bacterial infections in the human body, affecting millions of people worldwide each year. Many readers may have heard of “bladder infection” or “kidney infection” – but the underlying mechanisms, associated risks and emerging challenges (such as antibiotic resistance) are often not well understood. In this article, we will explore what a urinary tract infection is, the different types (from bladder to kidney), how they appear, why they occur, how they are diagnosed and treated, and most importantly, how they can be prevented and managed. Our goal is to provide a clear and authoritative overview – while remaining accessible to the general public – thus providing you with sound knowledge about this important health topic.
