Laymanz,
Before surgery, I had active Crohn's and would get anemic and have blood transfusions, too. At its worst, my hemoglobin went down to a 6, and I was extremely exhausted, so I really feel for you.
Ever since my colon and rectum removal two years ago, I have been disease-free and my blood levels have been excellent, so this surgery will really help you, too.
Hang in there, October 6th is right around the corner!
Cecilia
