Prior to my jpouch surgery I never had a cold or flu last much more than a day or two. Even working in a retail environment. Since having the jpouch done and returning to work I have been sick 3 times(in as many months) and this time, I have now been sick with a sinus infection for nearly five days. It is my understanding that a huge portion of a humans immune system resides in the large intestine, so is that why I seem to be more susceptible to bacteria now? I try to use hand sanitizer and wash my hands frequently, along with trying to remember to not touch my face, but I'm certain I do it without even realizing it. In any event just curious if anyone else ran into this and if there were any remedies you found to be helpful. Thanks!
