Hi I can understand your concern .... See by NSAiDS use you are having reactive gastropathy and you also have hiatus hernia in addition which can lead reflux ... Here are few advises ..... Excess spicy foods avoided .... Heavy meal restricted .... Small meal taken with frequent interval .... More water. .... Fruits taken more ..... Gastric irritants avoided like ..... -excess tea -excess coffe -smoking -alcohol -sour fruits -non veg diet ...... Avocados , peaches , apple like fruit taken more .... Head elevation while sleeping.... Excess coffe , chocolate avoided .... Take sleep two hour after taking meal at night .... If needed hiatus hernia surgically repaired. .. Take care .....
