The reduction in recurring infections was probably because the increase in urine volume drove more frequent urination, both of which flushed more bacteria from the bladder, the study authors said. This study is the first randomized, clinical trial to examine the common recommendation of adding water to the diet, the authors said.
Drinking 1.5 liters a day is the equivalent of about six cups of water or four 12-ounce bottles of water.
At least half of all women are at risk of what doctors call “acute uncomplicated cystitis” or “urinary tract infections” at some point in their lives. Once they get one, about a quarter of those women will get another within six months. Up to 75% of women will have another within a year.
The intense burning, itching and frequent urination can make life miserable.
But experts said women should know about other risk factors and be counseled on how to avoid them.
Common recommendations: Do not delay urination. Urinate immediately after intercourse, and practice good vaginal hygiene, which includes using “plain, unperfumed soaps to wash the area around the vagina (the vulva) gently every day,” according to the UK’s National Health Service. Avoid douches and perfumed soaps, as they can interfere with the natural balance of bacteria and pH levels.
And of course, listen to Mom and drink up.
