Hi, I am a bander but may be this might help. From my own experience I believe after the surgery you can feel bloated and the body is still experiencing some changes and u might tend to gain weight. I did gained 5lb and I was so worried but when my body got healed and use to the changes I started loosing weight. And also they always advice not to worry about any weight gain at this early stage because its the healing stage ;i am sure before u know it, you will start loosing weight real quick. So Cheer up girl
And also if you are struggling to eat then you should know that the wound in your stomach is still healing and you might find it difficult to cope. What stage are on? Liquid or mushy diet. Also try to drink plenty, it does help.
