I'm day 6 post op....and I haven't weighed myself...but I don't think I've lost any weight since the surgery. My clothes are all fitting the same. Is this normal?

Yes it is. You have been on a preop diet and probably lost some weight and it can take time for your body to catch up. Plus after surgery you tend to retain more fluid etc. And it takes a lot of weight loss before you start noticing a difference in clothes.

Don't panic. Just keep doing what you should be doing and the weight will come off. You didn't gain it overnight and the same is true for losing it.

I actually gain weight after surgery. But after a couple weeks I started to lose. Don't get discouraged.
