The answer in nearly all cases is exercise. Specific, targeted, effective exercise, not to become strong, but to regain CONTROL over your pelvic floor function and the ENDURANCE to hold on.
This exercise is known as pelvic floor muscle training (PMFT), or Kegel exercises.
Pelvic floor exercises can be done effectively on your own at home.
This website aims to give you a self-help route to effective pelvic floor exercises, by giving you the understanding that you need to find the best treatment for you and, where appropriate, the necessary guidance to help you to exercise effectively on your own.
If you are not in a position to help yourself, there are a number of options available through the NHS. You will need to speak to your GP to find out what they are.
It's worth bearing in mind that you may be in a better position to get the services you need if you can show that you have already tried the self-help route.
