A few years ago, I started having heart palpitation, I went to the cardiologist, they monitored it, did the whole ekg and everything came out good! I was hospitalized last year after having my son because I caught eclampsia and they saw I had low potassuim? Can this effect my surgery of a bbl that I'll have next week? I'm taking my vitamins, iron and eating healthy as much as I can right now.
