Welcome to life after bypass. I've had the constipation issue since surgery. I pretty much just settled for pooping every few days until about 4 months ago. I had a hysterectomy 3 months ago and was warned that I could do absolutely no straining after that while I healed or I could risk rupturing internal sutures. So I started myself on Miralax and Colace daily. Immediately after the hysterectomy, I even added in Milk of Magnesia for a few weeks just to make sure I truly had no straining. But yeah, the constipation is completely normal, unfortunately. Miralax and Colace will become your best friends. My surgeon recommended a shot of Milk of Magnesia mixed with prune juice daily and told me this as I was being discharged from the hospital after bypass. I really wish I'd taken his advice then. Not that my weight loss hasn't been awesome, but I wonder if it could have been even better had I been more "regular" for those first few months.
