I am a 30-year old female, active, in very good health, and I have SVT. I have episodes on average of once every two weeks, my HR gets up to 180bpm, and will last anywhere from 15 minutes to 8 hours. I know this sounds vain, but what are the chances I will gain weight after my ablation, assuming it is successful? If I maintain my activity level will I gain weight? Thanks~!
