Urinary Tract Infection - Symptoms, Causes & Treatment
A urinary tract infection (UTI) is an infection in any part of the urinary system including kidneys, ureters, bladder, and urethra. Most UTIs affect the lower urinary tract.
Overview
UTIs are among the most common bacterial infections, affecting approximately 50-60% of women at some point in their lives. Women are 30 times more likely to develop UTIs than men due to anatomical differences.
While most UTIs are easily treatable with antibiotics, recurrent or untreated UTIs can lead to serious complications including kidney infections and sepsis.
Symptoms of Urinary Tract Infection
- Burning UrinationPrimary
Burning urination (dysuria) is a painful or burning sensation during urination. It is one of the most common urinary symptoms.

Frequent urination is the need to urinate more often than usual. It can be a symptom of various conditions including diabetes, urinary tract infections, and prostate problems.

Abdominal pain is discomfort felt anywhere between the chest and groin. It can range from a dull ache to sharp, severe pain and can have many causes.
