Anemia Support Group
Anemia (or anaemia), which literally means "without blood," is a deficiency of red blood cells and/or hemoglobin. This results in a reduced ability of blood to transfer oxygen to the tissues, and this causes hypoxia; since all human cells depend on oxygen for survival, varying degrees of anemia can have a wide range of clinical consequences.
In an otherwise healthy 19 yr. old female, Anemia is generally caused by a Vitamin Deficiency. This can be lack of Iron, lack of B12 or lack of Folates any of these combined with a heavy menstrual cycle can cause Anemia. Your daughter is doing the opposite of what a Dr. is going to tell her to do. Treatment for all of these types of Anemia is to get more iron and protein rich foods into her diet, i.e. red meat, eggs, liver, oysters, clams, milk and cheese, whole grains, nuts and seafood.
So she may have to decide what she wants more to be a vegetarian or to go in the army. Supplements don't work as well as the Iron or B12 derived from foods.
I hope y'all get this figured out.
