Correcting Erroneous information from James. The credible sites mention nothing about food consumption as a possible cause of obstruction. Confirming what the doctor here has been telling me. I'm still likely to be at least a little bit careful. In my case, if it happens, it is the scar tissue from my cancer surgery, and them causing obstruction is a random event that is just going to happen if it's going to happen. I'm still likely to take slight Care at least in what and when I consume.
