Yes! Your body is adjusting to having more food again. I am 5 months post -op (sleeve) about week 4 i strayed the same weight about 2 weeks and then started losing steadily again. 5 months out and I'm still losing about 3 to 4lbs a week. Exercise is the key! I started off doing it 2-3 times a week and now I go to the gym 4 times a week. It also depends on how much you have to lose too. Heavier people like myself lose it a little faster.
Don't worry! You got this! ?
