STARTING WEIGHT (256.6) I went on a 10 day pre-op diet with which I lost 16 pounds. My 5th day post op I had reached 28 pounds lost. On the 26th I had gone back to 236 pounds. My coordinator with whom I still speak with has told me that it can be excess Water. I'm in my second week post op. What should I be drinking/doing to see some significant weight loss? PLEASE HELP ME!
