I am 9 days post op and have only lost 2 lb in the last week. I lost 20 lbs before surgery and am frustrated that I haven't seen hardly any loss this week. I am making sure that I get my protein in each day. What am I doing wrong? Or am I being unrealistic in my expectations? Going through all of this and not seeing the scale show much is frustrating.

Well done on your total weight loss so far. You probably being little unrealistic given a couple of things. Firstly you are in recovery mode, your body has inflammation, you are possibly still have some fluid retention due to the iv fluids and inflammation. Secondly you lost a lot of weight in pre-op.

There is a reason some doctors say don't weigh yourself in the first few weeks or even the first month.

If you are following your post op guidelines re food and fluid intake you will be fine, the scales will reflect your efforts soon.
