Which weight?

So, I'm going to Mexico in a week and a half for my RNY, just saw my personal MD and got weighed. My questions is, since I obviously won't be seeing my surgeon at regular intervals, which scale should I use for my weight? I feel pretty confident in the accuracy of my scale but wondered what others in similar situations do?

I don't know of any 2 scales that weigh the same so I would go with the scale at home.  It may be different or even inaccurate but it should tell you whether you have lost weight or not.  But you may be better off staying off it completely, at least for the first few weeks when you may find that there is a gain from the fluids you get at the hospital.  If you can hold off weighing yourself except weekly or even monthly you will be much happier with what you see.  If not then remind yourself that the number you see is for information only and not a personal reflection of your worth as a person then you may be able to get away with weighing more often.

You will probably be getting weighed at the doctor's office, too.  What I did was weigh myself immediately before I went, in the same clothes as I would be wearing and then I could compare weights on the different scales.  Again, the number is only for information purposes and that will help you gauge your progress and know what is working or what you may need to change, it is not to be used to make yourself feel worthless or discouraged.  It takes a while to divorce yourself emotionally from the number you see but it can be done.  I have weighed myself pretty much daily since my surgery 2 1/2 years ago and I use the information, especially now that I am learning maintenance.  I have no way of knowing what my body needs to live on so by keeping track of what I eat and what I weigh I can learn how my body works and how much fuel it needs.  

I use my home scale. In fact when I see my doctor, I tell the nurse not to tell me the weight their scale shows me. It totally freaks me out. I always weigh myself first thing in the morning after using the bathroom. Otherwise, what clothes I'm wearing, if I had recently eaten or drank water, will affect the scale. Plus, as the poster before said, I don't think 2 scales are the same.

All of them....the doc has his; the surgeon has hers and then I have the one I use at home. Too me the weight doesn't matter; except it shows me the progress in pounds. I care more about how I fit in my clothes....it's what I see and others see. As long as my battery is working in the scales, I use my own to see my weekly progress. I used to weigh myself daily, then realized that was starting to make me worry. Only Sunday Mornings, now.
