One in five women will have at least one UTI in a lifetime,
with 20% of these women experiencing reoccurrences. There is a very high prevalence
among the long-term care population due to polypharmacy, frequent catheterization, and incontinence.
Current Research on
Medical Nutrition Therapy
2016 – Largest study to date evaluated the influence on
cranberry product consumption on UTI incidence
39% reduction of clinical UTI episodes – 24-week consumption
of cranberry beverage
37% reduction of UTI with pyuria episodes – 24-week consumption
of cranberry beverage
Recurrent UTI
Management and prevention – eliminating risk factors that
increase incidence of recurrent UTI
Antibiotic prophylaxis – most effective medical treatment
Possible causes may

Nutritional
prevention strategies:
