In most cases incontinence is almost always curable even due to weak pelvic floor muscles.
My dad became incontinent due to weak pelvic floor muscles a few years ago and his doctor recommended doing Kegel Exercises and overtime after around 7 months of performing the Kegel exercises his incontinence was cured and he no longer need to wear the diapers he was wearing for incontinence.
Some people report it doesn't work but for my dad it worked and it's worth a try as you can't make anything worse by trying the Kegel exercises.
