I have had the band for more than 12 months and done pretty well but over the last couple of months beginning to experience what seems like heartburn, only lasts for a few minutes at most but the area it covers (around the breast bone) is gradully increasing. It started at about the size of the width of a pencil. It happens at any time, while eating or not. I had a hiatus heria fixed at the time of the op. Has anyone else experienced something similar?
