Hi Maxxim,
I've also had a similar experience with my band. I was banded in February of 2009. Things were going great and I was losing alot of weight. I was able to eat solid proteins but not things like bread or chips. Around June of 2010, I started noticing that I would get acid reflux at night. It was miserable and very painful. I also started to get sick frequently due to eating too much and trying to eat around the band. I was still happy though because I was losing so much weight. Eventually in August of 2010, I noticed I could only eat mushies and soups and then eventually just liquids. Again, it wasn't fun but I was losing weight so I was happy. One day in mid August, water and hot tea would not even go down. I tried every liquid but nothing worked. I would develop a mucus plug and would have to purge to get some relief. I finally decided to go see my lap band doctor. I was self pay so I was very worried. They did a barium swallow and saw that nothing was going through. I was told that my pouch was very inflammed and the band had almost slipped. My docotor was very worried and now, so was I. He had to completely unfill the band to give the pouch time to heal. It healed rather quickly and now I feel so much better. I can't think of any incidents where I was horribly sick or vomited alot. It just seemed to get worse and worse. Anyway, I feel so much better now. I really didn't want to see the doctor since I was losing so much weight but I feel so much better now. I tried to just stay on liquids to see if that helped, but it didn't. My advice would be to see your doctor as soon as you can before you do perminent damage. I was so close to having damage since I waited. Once the pouch healed, I was able to be refilled and I am back on track. Hope this helps!
