Copper and Zinc

There seems to be a strong connection with copper/zinc imbalances, low zinc, and low magnesium and HG. You can read about it here, here, and here (the latter has a commenter testimony about copper deficiency causing her HG). HyperGPregnancy suggests having an RBC Magnesium draw done which tests all three levels. I don't know about you...but I have copper pipes. There's not much more to add to this, other than it's another possible factor for some women with HG. Of which, I am more certain than ever, that there is not just one cause, but many possible causes.
