I'm very upset right now. I don't know how it happened but I've gained nearly 7 lbs in last week. As of today I am 16 days post op, I lost 15 lbs at my post op doctors visit a week ago and now I've gained. I'm on the same diet as before, I just switched up my protein drinks a bit. I'm worried because I'm drinking a ton but I don't feel like I'm going to the bathroom as often as I should. I think I may just be retaining water or something. I hope that's it. I even started going to the gym this week, but i still gained. I just feel its too early to be having these issues, I feel like I did all this for nothing. I hope the doctor will have an answer for me when I see him today.

I had the same thing happen. I think it's because you are starting to eat something. Not just drinking. Don't get discouraged. It will come off. I wish you the best of luck!

If your going to the gym its possible you've gained muscle mass and instead of loosing weight you've lost inches!

I think it was a combination of a few things, Water retention cause I'm not drinking enough, using milk with Protein drinks and other higher calorie Protein Drinks, and increased muscle mass.

My doctor weighs me on this high tech scale that gives out detailed readings. It said I gained 6 lbs, but lost 1.5 % body fat. So who knows...

Use water with your protein instead of milk. Cut calories where you can and cardio exercise daily.
