Since being diagnosed with ceoliac disease, I have also been told that my iron is very low and the specialist recommended IV injection. My GP said that this is risky and needs to be administered in hospital and you can have a bad reaction, i.e. collapse. My GP said there are iron injections but Doctors stopped doing these as they are so painful. It has to be injected into the muscle. I know I had them for 3 weeks many years ago when I had my first daughter. Have any of you had to have any of this? Or have you just gone for tablets if your iron is low?
