It’s apart of some candida symptoms you will get as you detox. I had it before and during the diet, but now I don’t get it anymore. I used to get palpitations 6 times a day or more.
I think in general it might mean you have a weak heart; if you were to get it checked out I think a doctor would say not to worry about it. It freaked me out as well; the first time I had it I went to the ER and they said it was due to hyperventilation.
