If you are lucky, a short course of antibiotics will save you from infection. However, in some women, the infection returns again and again with discouraging regularity, sometimes after a few days, sometimes after weeks. Why does this happen? “Bacteria get into the bladder all the time, explains Dr. Whitemore, but this does not always lead to infection. They are simply washed out of the bladder, this is its main defense mechanism. ”
However, in some women, the natural defense mechanisms of the bladder are weakened. According to one theory, for those who suffer from a recurrence of urinary tract infections, the walls of the bladder are such that the bacteria “stick” to them and are not carried away with urine. Experiments are underway to find ways to prevent bacteria from attaching to the walls.
