Report Burping in Dysautonomia Discussion Posted May 1, 2019 My son ( 28, ME / POTS) has been bedbound for 1,5 year. The last few months he developed constant burping, until now no medication helped. He will soon start taking Nalcrom, prescribed by his cardiologist.,suggesting it might have something to do with MCAS. He cannot sit up for more than a few minutes, so he is eating mostly laying down. Anyone having the same problem? Erica.
