So sorry to hear this. I have a chronic infection, also. The drs say it should be no problem with the surgery. *sigh* Thought I had a flareup a month or two ago, turned out to be bed bugs, LOL!
I'm sorry you're having problem with diarrhea. I don't have C-diff, but it's still something I have to be light about, anyway.
I hope you get better, soon. I just joined this forum today. I'm on my way to the vertical sleeve. I can't wait. I gained 8 lbs in one week, from last week for pete's sake. I eat, then don't go for days. That's my natural 'clock'. I can't wait to share with you guys.
