GP phoned on Friday to tell me that a blood test has showed that I'm 'a bit' anaemic. My hb is 8 and should be around 12-15 
Can anyone tell me, how low then is 'a bit' anaemic? Is 8 really 'a bit' or actually in fact rather 'a lot' anaemic?! What can I do to sort it? GP has just said adjust diet - more red meat
and green veg etc. A nurse friend has suggested that with an hb of 8 (she described this as very low) I should have been given iron tablets.
Any tips on what to take and how long to expect it to work in bringing the iron level up?
