I had the band put on in January 2005. I became pregnant in August and my son was born in April 2006. I kept the band tightened until the 4th month. I had to deflate it because I continued to lose weight. After it was deflated, I only ate a little more than when the band was tightened. I don't know if this is because the placenta was pushing up on my stomach or what. Six weeks after his birth I went to have my first adjustment and it was found that my band had slipped. I had to have the surgery completely re-done. They took the old band out and put a new band in. The doctor says it probably slipped because I threw-up too much during the pregnancy. I was super sick the entire time. I began taking anti-nasuea medicine in the 3rd month, but, I guess it was too little too late from the band aspect. My doctor says that there is no guarantees that this one won't slip again if I decide to have another. I will need to start the anti-nasuea medicine as soon as a start to feel morning sickness if I decide to have another one.
