A urinary tract infection (UTI) can affect any part of the urinary system, kidneys, bladder or urethra.
More than 3 million Americans, mostly women, experience a UTI every year.
Symptoms include frequent, painful urination, pelvic pain and traces blood in the urine. The infection does not normally last long, and most patients self-diagnose.
For many, the first port of call is a box of cranberry juice. However, new research suggests that while cranberry capsules can help, cranberry juice may be little more than a panacea.
Dr. Timothy Boone, PhD, vice dean of the Texas A&M Health Science Center College of Medicine in Houston, and colleagues wanted to know if cranberries can really help.
