CBT. Is “cognitive behavior therapy”. I have read clinical studies ( unfortunately only very small groups) that found it to be transformative for supragastric belching, but NIH website also has more info that is encouraging. None of my numerous doctors , GI and alternative, have ever suggested it as a possibility even, but my new GI referred me for therapy , along with speech therapy ( for which there is also positive feedback in google land on non commercial sites). My last ENT about two years ago would not prescribe it, saying it is not worthwhile. I intend to try it if needed after I do speech therapy and feel like I still need help.
