DEAR MAYO CLINIC: As a woman in my mid-60s, I have been diagnosed with a urinary tract infection for the first time ever. I was surprised to find out that I don't need antibiotics because I don't have any symptoms. There's a lot of conflicting information online about UTIs, like whether every infection needs to be treated and if sex causes an infection. Can you help me distinguish between UTI myth and fact?
ANSWER: Urinary tract infections, also called UTIs, are the most common infection for women in the U.S., so you are not alone. About 40% of women will have at least one UTI in their lifetime, and 1 in 10 postmenopausal women had a UTI in the last year.
A UTI is an infection that occurs in the urinary system, such as the bladder, ureters and kidneys. Most infections involve the bladder, which is known as the lower urinary tract.
