GERD
First Step is NOT diagnosis, it is life style modifications and PPIs
THEN EGD with Bx to see if its gastritis vs barret's
THEN decide between PPI (GERD), Nissen (Barret's), or surgery (Cancer).
remember to get a 24-hr pH monitor which is the best test (though rarely done) before you go to surgery. you get every test under the sun (manometry, 24-hr pH, egd) before you go to surgery
