I had my rny almost 14 years ago. I’ve had two short series of iron infusions to address lower hemoglobin levels. Keep an eye in it. I found out about the issue when I fell asleep at the wheel going 85mph on I95. Luckily it was a quiet Saturday and although I hit the jersey barrier, the only damage was to my car. It prompted a transfusion to make sure I got my levels higher, but it was the rudest wake-up call of my life. BTW, I too have lost 120+ and maintained it for almost 11years.
