Bowel care position

For The past couple months I've had to do BC laying down on my side. As sitting down in the commode even though that's what I've been doing since I left the rehab started to take hours and not being fully "affective". So I started doing it on my side and comes much quicker and larger. But does doing this continuingly on my side potential side affects on intestinal system more junk left behind because it's not aided by gravity
