I have a small sliding hiatus hernia (<5cm). I just wanted to know if anyone has an idea of what 'sliding' means? I understand that it means the stomach can potentially move between above the diaphragm and below it, however in reality how often does this movement take place? Does this movement happen everytime you, for e.g., swallow? Or does it happen once a month, year etc. for any random reason? Is the stomach likely the be above the diaphragm most of the time, or below it most of the time?
Also, does anyone know if its possible to manually move the stomach back down if its stuck with massage techniques or is that just nonsense?
Thanks for the help
