Had my orbera ballon inserted 11 days ago and only lost 4 pounds. Is something wrong?

Hanna, the fact that all of your symptoms have resolved is very GOOD news. The first week to two weeks are all about adjusting to the balloon. We don't worry too much about the scale during that time. Once you've adjusted to the balloon (which you now have), you can then focus on weight loss for the next 6 months. It's completely normal to forget that the balloon is there. That's the goal -- you shouldn't have side effects continuously. As far as the weight loss, it will be steady but at times may slow down or even stall. Your body is going through many changes during this time, and the scale doesn't tell everything. Patience is key! 

You should speak with your provider. What does your nutritional coach suggested? Are you not feeling any fullness from balloon? Ate you eating same amounts as before the balloon. It is definitely best to speak with you provide and nutritional coach.
