What kind of metal sensitivity are you wondering about?
I’ve been interested in this topic as well. I’m sensitive to nickel in both jewelry and foods (I get eczema when I eat foods high in nickel, like chocolate). Recently, I’ve wondered if my genetic variations have led to a build up of nickel in my body to the point that I became sensitive. I have some genetic variations that mean my liver is not very good at detoxing, so maybe I just have too much nickel in me and need to pull it out through detoxing or chelation, although I would have to go super slow and gentle to not overburden my inefficient liver!
Contact sensitivity to nickel is mostly from environmental factors, not genetic:
A low nickel diet and/or nickel chelation are possible therapies:
Thanks for your response! I have been having health issues and found out that I have metal clips in me from when I had my gallbladder removed. I am also unable to wear most jewelry because of sensitivity to metals. I have seen many Dr’s that tell me they have never heard of people being sensitive to sergerical clips. I appreciate the links you attached. I didn’t know if there are any genes related to metal sensitivity.
