It is possible that it could be your gallbladder. Also what comes to mind is GERD... have you had yourself checked for this? I have GERD (hasn't flared lately) and I will get really full and start burping. Another reason for this is that you may be swallowing too much air when you eat. Eating too fast and drinking through straws are the culprit of these. I'm sure someone will come and talk about
gallbladder disease... we have a few on here.
