Wills - I am sure you are going to say :she never gives up"... and I don't
But I thought the last sentence was appropriate in your case too....

Extract from Primal Health Research newsletter, vol 10 no 3:
In many countries, the amount of red blood cells pigment (hemoglobin concentration) is routinely measured in pregnancy. There is a widespread belief that this test can effectively detect anaemia and iron deficiency. In fact, this test cannot diagnose iron deficiency because the blood volume of pregnant women is supposed to increase dramatically, so the hemoglobin concentration indicates first the degree of blood dilution, an effect of placental activity. A large British study, involving 153,602 pregnancies (17), found that the highest average birth weight was in the group of women who had a hemoglobin concentration between 8.5 and 9.5. Furthermore, when the hemoglobin concentration fails to fall below 10.5 there is an increased risk of low birthweight, preterm birth and pre-eclampsia. The regrettable consequence of routine evaluation of hemoglobin concentration is that, all over the world, millions of pregnant women are wrongly told that they are anaemic and are given ironsupplements. There is a tendency both to overlook the side effects of iron (constipation, diarrhea, heartburn, etc.) and to forget that iron inhibits the absorption of such an important growth factor as zinc (18). Furthermore, iron is an oxidative substance that can exacerbate lipid peroxidation (free radicals) and might even increase the risk of pre-eclampsia (19).
