Urinary Tract Infection (UTI)
Overview
A urinary tract infection (UTI) occurs when bacteria — most often E. coli from the gut — enter the urinary tract and multiply, typically in the bladder, causing inflammation and the classic burning sensation.
UTIs are one of the most common reasons for urgent medical visits and are usually straightforward to treat, though infections that spread upward to the kidneys need prompt attention.
Symptoms
Causes
Bacteria travel up the urethra into the bladder. Women are more prone to UTIs due to a shorter urethra; other contributing factors include sexual activity, catheter use, incomplete bladder emptying, and diabetes.
Risk Factors
Diagnosis
A urine dipstick test screens for infection quickly, while a urine culture confirms the specific bacteria and the antibiotic it will respond to best — particularly useful when infections keep recurring.
Complications If Untreated
Untreated infection can travel up to the kidneys, causing a more serious infection called pyelonephritis, and in rare severe cases can progress to a bloodstream infection requiring hospital care.
Treatment Options
Prevention Tips
Good hydration, urinating after intercourse, avoiding delayed urination, and proper hygiene meaningfully lower UTI risk.
Lifestyle Advice
Drinking enough water throughout the day, avoiding holding urine for long periods, and wearing breathable cotton underwear all support urinary tract health.
