Urinary Tract Infection - Prevention
Urinary Tract Infection - Prevention
There are several simple, do-it-yourself techniques that may prevent a urinary tract infection. Some may work some of the time, or only in some women. But, because they carry no side effects, they certainly are worth trying to prevent the often painful and bothersome symptoms the infection can bring:
Drink plenty of fluid—the equivalent of six to eight 8-ounce glasses -- every day to flush bacteria out of your urinary system. This does NOT mean eight glasses of water in addition to everything else that you drink.
Make sure you're getting vitamin C in your diet, either through diet or supplements. Vitamin C, or ascorbic acid, makes your urine acidic, which discourages the growth of bacteria. Drinking cranberry juice may also produce the same effect. Cranberry tablets are a more concentrated form of cranberry juice without the sugar content.
Urinate every two to three hours. Keeping urine in your bladder for long periods gives bacteria a place to grow.
Avoid using feminine hygiene sprays and scented douches. They also may irritate the urethra.
If you suffer from urinary tract infections more than three times a year, your health care professional may suggest one of the following therapies to try to prevent another recurrence:
a low dosage of an antibiotic medication such as trimethoprim/sulfamethoxazole or nitrofurantoin, taken daily for six months or longer
a single dose of an antibiotic medication taken after sexual intercourse if it is determined that your UTIs are related to sex.
a short, one- or two-day course of antibiotic medication taken when symptoms appear
Research
New research funded by the National Institutes of Health suggests that a woman's blood type may play a role in her risk of recurrent UTIs. Bacteria may be able to attach to cells in the urinary tract more easily in those with certain blood factors. Additional research will determine if such an association exists and whether it could be useful in identifying people at risk of recurrent UTIs.
Studies have found that children and women who tend to get recurrent urinary tract infections are likely to lack infection-fighting proteins called immunoglobulins. Children and women who do not get UTIs are more likely to have normal levels of immunoglobulins in their genital and urinary tracts. However, even most patients who get frequent UTI's have normal immune systems.
Vaccines are being developed to help patients build up their own natural infection-fighting powers. Vaccines that are prepared using dead bacteria do not spread like an infection; instead, they prompt the body to produce antibodies that can later fight against live organisms. Researchers are currently testing injection and oral vaccines as well as vaccine suppositories that are placed in the vagina.
