A 2000 survey by Bayer Pharmaceutical of more than 1,000 women found that 58 percent have had at least one urinary-tract infection (UTI) -- about 10 percent more than previously thought. Of those who get UTIs, the average number of infections over a life span is 5.4.
The survey points to a lack of understanding among women about UTIs. While 87 percent had heard of Escherichia coli, only 53 percent knew it causes 80 to 85 percent of UTIs.
Some 73 percent had heard of antibiotic resistance but only 21 percent had discussed it with their physician, the survey found. And only 21 percent believe it could be a cause of recurring UTIs.
Bayer researchers say 94 percent of women who got a UTI went to their doctor for antibiotics, but many also had tried a home remedy such as cranberry juice. Prescription antibiotics proved more effective than self-treatments or over-the-counter medications, 71 percent of respondents said.
UTI, one of the most common infections seen by doctors, account for more than 9.6 million office visits and 1.5 million hospitalizations a year. They affect women more frequently than men. Symptoms can include an urgent and frequent need to urinate, sharp pain or burning sensation and a low volume of urine, tinged with blood and a strong odor.
