The operation I had was to remove most of my colon, then they attached the
small & large (colon), back together. The area they needed to remove from the
small intestines to attach the colon was the area which helps with the
processing of B12. I used to get B12 shots each month but now am taking time released
ones every day. Hope this helps.
Hugs-prayers & pain free moments to all of my extended family!!!!!!!!!!!!!!!!
