I appreciate you responding to my post. I know that my Calcium level is good. When I take anymore Calcuim my blood pressure drops through the basement. My Mg was fine but i do sometimes lack Sodium. I know I can not go conventional medical treatment due to the fact it drops my heart rate extremely low. They also have just found that I have an underactive thyroid. I am now going to research it to see what all I can find on it here at curezone. Do you think my underactive thyroid could be causing my heart problems. Or do you think there is still an underlying cause? I have tried several cleanses. I am planning on going on another Juice fast and maybe some cleanses at the same time. I do believe my immune system is low. Once i get ride of something another pops up. If you have any suggestions please let me know.
