A lot of the GB pt's that have posted this same problem are out post op about the same length of time when this happens to them. It seems to be 4-5 yrs when they start to have problems. I have heard that it is from the ~type~ of procedure that you have, not all are the same type as you know. My sister 1 yr post op and cousin 4 yrs post op both had this done and both remained on iron in their prenatal vitamins, plus iron supplement 2X daily and B-12 shots monthly. They still only absorb a little each day but have been able to keep their Ferritin up at this point.
You can use the search box at the top of this page and search for others on this subject and there are many threads here with lots of information under IV infusions.
The bottom line is that you most likely will have this procedure of IV iron replacement therapy for the rest of your like. That's just how it works for a certain percentage, I forgot what that was now, but it happens to many people. At least you can fill your stores quickly and feel better while building HGB in a much shorter period of time. The information that the doctors and posters here have told you is correct. Good luck.
