Sorry about the pun, but it will.
I had a similar problem at about the same time post-op, and I asked doctor about laxatives, including Fiber ones (believing they might be more "natural" than MOM or chemicals), & he advised not to take any pills or pharmacy products. Fiber swells in the gut, could cause restriction problems, and he recommended nothing more than raw fruit (ripe bananas, if you can swallow them) and juices (including prune), smoothies, etc.
He also suggested that partof the problem may simply be reduced quantities going in means reduced quantities coming out... another thing we have to adapt to.
