So I am 12 days post op and have done okay with the weight loss. But today when I weighed myself I gained 1.5 lbs from yesterday. I've been trying not to weigh myself daily but over the past few days I have not moved the scale so I was curious and saw the gain. I'm doing everything they tell me to do. I want to cry!

Forget it about it. Your body will go up and down. It wants to grab on to every calorie and pound and retain it. This creates stalls and it will happen many times in this process. If you are following the process, you will lose weight. Keep your head up.

totally agree it is not fat gain, it's a fluctuation in fluids. Don't worry!!!

Day to day changes are completely normal. I like to keep track of my weekly and monthly losses. And usually around week 2 -3 there is a stall.
