As a flight attendant, my experience with the band has not been a good one. I wrote a letter to my surgeon regarding aviation and the band for his case studies. I have a complete unfill and still feel chest pain. However, i must tell you that upon banding three years and four months ago had a 5cm hiatal hernia. Last year my crew encountered severe turbulence that required months of PT. Since I had pain all over I did not contribute it to the band. Upper GI's and endoscopies reveal it has herniated above the diaphragm. My port site has always been sore, very touchy, I yelp when my husband brushes his hand over it. So, if you are considering the band and are an aviator, be sure to discuss your concerns with your surgeon. Keep in mind while making your WLS decision, this industry has a higher injury rate than construction workers. Case studies would be useful (occupational/WLS stats) in making a decision. I should have known better. It is common sense that anything filled with fluid or is sealed on an airplane at a certain altitude may not remain intact.
