In every issue of WebMD the Magazine, we ask experts to answer readers' questions about a wide range of topics, including some of the most common beliefs about medicine. In our September 2011 issue, we asked Jane Miller, MD, an associate professor of urology at Washington University's School of Medicine, about the link between diaphragms and painful bladder infections.
You're toiling on the treadmill, Stairmaster, or recumbent bicycle -- and the accident happens: a little urinary incontinence. Small leaks can occur whether you're a teen or a woman in her 20s and upward. Often incontinence starts after childbirth or as the result of athletic injuries. Some men have incontinence problems after prostate surgery.
"Unfortunately, people [with incontinence] stop doing things they enjoy, like high-impact aerobics," says Roger Dmochowski, MD, a urologist and director...
The reason is that urinary tract infections (common symptoms include burning pain and a constant need to pee), get triggered by bacteria, most often E. coli, which lives in the colon and rectum. And diaphragms are used with spermicides, "which can kill off the protective bacteria in the vagina, as well as change the pH balance of the vagina," Miller says. "This can increase growth of the kinds of bacteria that cause UTIs and bring it closer to the urethra and ultimately the bladder."
If you have recurring infections, you may be better off using alternative birth control methods, such as an IUD or the Pill. General tips for avoiding bladder infections include: Drinking plenty of water, peeing when you need to (instead of "holding" it), and wiping from front to back after urinating and bowel movements.
