hi,i had a
gastric bypass 1 yr ago
and my mom had hers 3yrs ago ,she uses ibprufen all the time for her pain
and the dr prescribed it knowing about her g-bypass,also i take it on and off if i have very bad headache etc and never had any probs,i think the prob is if you take it every day for long eriod of time and thats not good for anyone never mind us as it can damage ur insides,so it goes for every one,but to take it on and off is fine,i asked my dr.
