Bladder Infection (Urinary Tract Infection—UTI) in Adults
View or Print All Sections
Definition & Facts
Bladder infections are the most common type of urinary tract infection (UTI), but any part of your urinary tract can become infected—the urethra, bladder, ureters, and kidneys. Your age, habits, or health conditions can make a UTI more likely.
Symptoms & Causes
Symptoms of a bladder infection may include a burning feeling when you urinate. Most infections in women are caused by bacteria from the bowel that reach the urethra and bladder. Most infections in men are the result of problems that restrict normal urine flow, such as an enlarged prostate.
Health care professionals use your medical history, a physical exam, and tests to diagnose a bladder infection. If you have repeat infections, your doctor may order additional tests to find the cause of your infection.
Treatments for bladder infections and other UTIs may include antibiotics and drinking lots of liquids to help flush bacteria from your urinary tract. Changes in habits, hygiene, or birth control method may help prevent another infection.
Eating, Diet, & Nutrition
Experts don’t think eating, diet, and nutrition play a role in preventing or treating bladder infections. If you have any type of UTI, talk with a health care professional about how much to drink each day to help prevent or relieve your infection.
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and other components of the National Institutes of Health (NIH) conduct and support research into many diseases and conditions.

The Urinary Tract & How it Works
The urinary tract is the body’s drainage system for removing urine, which is composed of wastes and extra fluid. In order for normal urination to occur, all body parts in the urinary tract need to work together in the correct order.
