The drip is prescribed by a doctor. He does not know for sure why it's low. A while back I got the swineflu which put me on a respirator and I had a number of complications as a result.
I've been on a number of medications since, and regular blood work. Maybe it's the drugs, I don't know, or maybe I had it previously without knowing. I had one drip already, had to sit in the office for a half hour looking out for allergic shock.
Does your GF feel it when her iron is low, eg fatigue? I was asked if I had more energy after the drip but I couldn't really feel it. I'm feeling pretty tired now, hopefully it gives me a jolt of energy this time.
She has made bloodwork appointments in the past based on how she feels and they inevitably recommend a transfusion. Not edge of death or anything but they prescribed. She hasn't ever gone in for bloodwork when feeling fine, however, so whose to say if that would have come back low also, since there were at least a couple heavy periods between transfusions?
She hasn't had a test or transfusion for awhile but I remember her saying she felt a bit better, but it wasn't like night and day. Mind you, there were complicating factors as well, being stressed to tears with a nightmare foster kid, who is thankfully history (violent little bastard).
You're a Swede, right? Now... you can't mention The Rona without politics running off with the damn thread but I use Sundstrom safety gear which comes from your neck of the woods. Their SR200 mask is the duck's nuts, coupled with their SR510 P3 filter which they claim filters virus sized particles, your risk would be greatly reduced.
