If you're 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 immediately after a few days, sometimes after weeks. Why does this happen? “Bacteria enter 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 protective mechanisms of the bladder are weakened. According to one theory, in those who suffer from recurrences of urinary tract infections, the walls of the bladder are such that the bacteria “stick” to them and are not carried away in the urine. Experiments are now underway in order to find ways to prevent bacteria from attaching to the walls.
