Hello! Both my Sister & I are going for LB surgery; I recently found out that I have a "slight" Hiatal Hernia...my sis found out about her Hernia a few years ago. From all that I know (which is limited...my surgery is coming up soon, hopefully in March) the Hernia is a concern, but it is also something that can be dealt with easily. It is quite common for people that are obese to have a Hernia, from what I'm told.
