I don't know for sure but I think I might be starting to retain fluid. I have gained 10 pounds lately. Can't really say when I started gaining it but it has definitely been in the last couple of months since my last doctor's appointment. Not only that but I have been having more irregular heartbeats lately and the odd dizzy spell which I haven't had many of either since I had surgery the end of may. If I could justify the weight gain then that would be one thing. But I have been eating well balanced meals and avoiding junk food so I know my weight gain isn't from my diet. Anyway made my cardio's appointment for december 7th so hopefully I can get to the bottom of it then.
