First: This is my concern with people going out of the country for any type of surgery. Cut and dump. They get their money and that's the end of your care. I am sure this is not the case with every surgeon but it isn't a rare occurrence either. Unfortunately that is the risk you take.
Second: Everyone is different and everyone stalls. Your body is in shock, and now you are eating a fraction of the calories it was used to before surgery. It basically goes into starvation mode and stores EVERYTHING it can until it realizes it is not actually starving and this is the new normal. Your body will adjust, the human body is quite amazing.
I lost like 12 lbs the first week and then nothing for like a month but then my body was like oh ok and I started dropping weight like crazy. (102 lbs in 6 months) I am currently in another stall and have lost 2 lbs in a few days shy of a month now. It does suck but it will pass.
The bottom line is if you have a calorie deficit you WILL lose weight. The surgery helps you be able to eat less, resulting in less calories.
Try to stay off the scale for a while, measure yourself and find other ways to see the results. Smaller clothes, non-scale victories, etc.
be patient, you got this!
