Respected user, hi I evaluated your query thoroughly. * All symptoms narrated don`t fit in the typical picture of exclusive IBS, rather there is definite underlying pathological process / inflammatory process going on inside the body which needs proper clinical evaluation along with mandatory tests as per consultant`s decision. * So get an appointment with doctor & solve the issue. * Till then drink plenty of liquids to maintain your hydration. * Avoid oily / spicy / nonveg stuffs. * Antacid tablets with antacid syrups do help to some extent. Hope this clears your doubts . Thanks for using Health care magic & keeping trust in our medical services Regards .
