I've noticed this in my husband. He has had three hernia operations. I don't think he digests food as well as he did. He also isn't as active. He tends to sit around more. He still eats as much (if not more). I think I have my answers!
Not to say that this is so in your case though. What type of hernia did you have? Do you think your digestion is more sluggish?
