My dad is experiencing constant burping from past 4 weeks. General physician prescribed pantocid citing it as a stomach acid related issue but that did not helped. So it was related to his anxiety issues for which he is already taking psychiatric medicines namely - daxid, etizola and quel 50. The psychiatrist also prescribed pentopump but that medicine also didn't helped in stopping burping. Wanting to know if there could be any other underlying reason for continuous burping?
