I was banded 4 weeks ago and getting ready to resume normal food tomorrow. I initially lost 22 lbs post banding (weeks 1-3) but noticed that I have been gaining weight (5 lbs) in the last week. Last couple of weeks I have been eating soft food but small plates, no beverages 15 minutes prior 60 minutes after meal, not more than 1500 calories a day, etc, etc....

Should I be concerned or weight fluctuations normal ? My next doctor's visit is in a couple of weeks. Is this an indication that I should get a fill?

Completely normal for lots of people. At four weeks I completely stopped losing anything and stayed like that for weeks longer. Then I had my first fill, and it just started dropping. Your first fill should be done on the timeline your doctor suggests. Your body has just lost a ton of weight at one time and it is adjusting. Mine did that all along... drop a lot then stall for months, then drop, then stall. It was annoying sometimes, but now looking back I realize how important the stalls were for my self-awareness and knowledge.

Congratulations on doing wonderful things for yourself!

Yup, I'm similar, I'll lose 2-3 in 1 week, gain back 1 or 2, then hold steady a couple weeks, I guess while everything evens out. After my initial post-op loss when I started semi-normal foods, I gained 5 in a week, even though I was exercising and eating 1200-1300 calories a day. Sometimes I think my body is 2-3 weeks behind my scales.

Yup, yes, normal. I just had my second fill and am just now having restriction. And I was hungry! It was everything I could do to not gain anything. I only maintained. Didn't gain. But many people do gain. So, in answer to your question, yes, people gain. But if you're careful you can maintain or even lose a little more. Best wishes!!!
