A urinary tract infection (UTI) is an infection in any part of your urinary system–your kidneys, ureters, bladder, and urethra. Most UTIs involve the bladder and urethra. Bacteria, usually E. coli from the gut, are the most frequent culprits.
Common UTI Causes
The primary cause is bacteria entering the urethra and traveling up to the bladder. Several factors increase your risk: holding urine for extended periods, infrequent urination, not wiping correctly after bowel movements (from back to front), sexual intercourse, and certain anatomical factors (e. g., shorter urethra in women). Pregnancy also increases vulnerability. Certain medical conditions, including kidney stones and diabetes, can also contribute.
Less Common Causes
While less frequent, other bacteria, fungi, or even viruses can occasionally cause UTIs. Certain medical devices like catheters can also introduce bacteria, increasing infection risk. Proper hygiene and prompt medical attention are vital for managing UTIs effectively.
