colon cleanses

can we use colon cleanses after RNY? are they safe?

I'm pretty sure you will NEED TO use them.... post-op you tend to be extremely "backed up".

Vets, correct me if I'm wrong?

That may depends on the cleanse. Like with everything else- use your comon sense.
Some coon cleanse use laxative herbs. That will work same as before RNY. other s- use a lot of bulking agent - fiber, powdered item - this you have to be careful - if too much fiber i sused - or not enough water - that may casue the opposite effect - severe constipation. 
 Some of the "colon clenase" itmes - may have too much sugar, or otehr stuff - not that good for us.

I use colon clenases - but in moderation, and only the ones that can be used by someone with RNY...
 

 I just had my RNY and the only thing I was told I could use was milk of magnesia but while in the hospital they gave me something to help and they made sure I had a bowel movement before I left. It'll probably be whatever your surgeon thinks is best for you.
