Can a colon cleanse hurt a gastric bypass patients stomach?

I've been taking Dr.Natura's Colonaide for a few days now and the results are great. I've done my research and know its perfectly natural for the intestines and all that to bloat. The problem is that it feels like my stomach has expanded and i'm able to drink much more than normal. I'm worried this could effect me after I stop the cleanse. Please someone help!
