Urinary tract infection - Lifestyle Changes

Description

An in-depth report on the causes, diagnosis, treatment, and prevention of urinary tract infections.

Alternative Names

Cystitis; UTI

Lifestyle Changes:

Although there is no evidence that good hygiene makes a real difference in preventing UTIs, it is always a wise practice. The following are some hygiene tips:

Clean the genital and urinary areas from front to back with soap and water after each bowel movement.
Keep the genital and anal areas clean before and after sex. Urinate before and after intercourse to empty the bladder and cleanse the urethra of bacteria.
Avoid tight-fitting pants.
Wear cotton-crotch underwear and panty hose, changing both at least once a day. (Mild detergents are best for washing underwear.)
Take showers rather than baths.
Avoid bath oils, feminine hygiene sprays, douches, and powders. As a general rule, do not use any product containing perfumes or other possible allergens near the genital area. Douching is never recommended as it may irritate the vagina and urethra and increase the risk of sexually transmitted diseases.
Choose sanitary napkins instead of tampons (which some doctors believe encourage infection). Napkins and tampons, in any case, should be changed after each urination.
Drink plenty of fluids and urinate frequently.

Appropriate hygiene and cleanliness of the genital area may help reduce the chances of introducing bacteria through the urethra. Females are especially vulnerable to this, because the urethra is in close proximity to the rectum. The genitals should be cleaned and wiped from front to back to reduce the chance of dragging E. coli bacteria from the rectal area to the urethra.

Sexual Precautions

The following recommendations may reduce the risks from sexual activity:

In women using contraceptives, consider alternatives, particularly if exposed to spermicides from condoms or diaphragms. Discuss the best contraceptive choice with a doctor.
Avoid sex with multiple partners. This can cause many health problems, including sexually transmitted diseases and UTIs.

Cranberries, Blueberries, and Lignonberries

Cranberries, blueberries, and lignonberry, a European relative of the cranberry, are three fruits that may have protective properties against urinary tract infections. These fruits contain compounds called tannins (or proanthocyanadins). Tannins may prevent E. coli bacteria from adhering to cells in the urinary tract, thereby inhibiting infection. Cranberry juice is the best-studied home remedy for UTIs. Some studies have indicated that cranberry juice may help decrease the number of symptomatic UTIs, especially for women with recurrent urinary tract infections.

It is not clear what the optimum dosage is for cranberries, or whether it is best to use juice or tablet form. Some research recommends drinking at least 1- 2 cups of cranberry juice daily, or taking at least 300 - 400 mg in tablet form twice daily.

Probiotics and Lactobacilli

Probiotics are beneficial microorganisms that may protect against infections in the genital and urinary tracts. The best-known probiotics are the lactobacilli strains, such as acidophilus, which is found in yogurt and other fermented milk products (kefir), as well as in dietary supplement capsules. The probiotics bifidobacteria and GG lactobacilli may also be helpful. Other probiotics include the lactobacilli rhamnosus, casel, plantarium, bulgaricus, and salivarius, and also Enterococcus faecium and Streptococcus thermophilus. Not all studies show a benefit for probiotics in preventing urinary tract infections. More research is needed.
