Lactobacillus & Urinary Tract Infections

Evidence is emerging to suggest that Lactobacilli may be useful in the prevention and treatment of urinary tract infections (UTI), according to researchers at the Canadian Research & Development Centre for Probiotics. However, as of 2010, further research is still needed to support this claim.

  1. What are Lactobacilli?

    • According to the National Library of Medicine, Lactobacilli are probiotic bacteria that produce vitamin K, lactase and beneficial anti-microbial substances including acidolin, acidolphilin, lactocidin and bacteriocin. In humans, Lactobacilli are naturally found in the small intestine and vagina.

    Potential Treatment

    • The urinary tract consists of the kidneys, ureters, bladder and urethra. UTI's occur when bacteria, such as E. coli, invade these areas. A study published in the "Journal of Physiology and Pharmacology" explains that UTIs in women are often caused by uropathogenic strains of E. coli colonizing in the vagina.

      Researchers at the University of Wisconsin Medical School found that compounds secreted by Lactobacilli may be able to prevent and treat UTIs by inhibiting the growth and colonization of E. coli.

    Side Effects

    • According to the National Library of Medicine, the most common side effect associated with Lactobacilli acidophilus is abdominal discomfort or gas.

      Some women also may experience a burning feeling in the vagina after using Lactobacilli acidophilus vaginal tablets.

    Considerations

    • Although generally considered safe, the National Library of Medicine recommends people with artificial heart valves, severely weakened immune systems or intestinal damage not consume Lactobacilli acidophilus.

      Pregnant and breastfeeding women should also consult a physician prior to use.

    Warning

    • Always seek medical attention if you suspect a UTI. According to the National Women's Health Information Center's website, if not properly treated, UTIs can spread and cause serious problems in the kidneys and other areas of the body.

      In pregnant women, a UTI may increase the risk of high blood pressure, early delivery and other problems. Pregnant women are also more susceptible to kidney damage from a UTI.
