Lately I have been very thirsty and have been drinking more and of course it makes you go to the loo a lot. I am going to the GP next week so hopefully it can be investigated. Because I am drinking a lot I am wondering if I am washing all important minerals out hence more problems with AF and ectopics. I know sometimes when I am in full blown AF I go to the loo about every 15 mins. I know that dehydration can cause AF sometimes it does sometimes with me.
