hi. noted history of gallstones and severe epigastric pain. how long have you been experiencing the epigastric pain? is it associated with food intake (specifically after a fatty meal), bloatedness, etc.? it may or may not be related with your gastritis. but in gallstones, the most common area of abdominal pain is epigastric in location then right upper quadrant of the abdomen, sometimes with radiation to the flank area, back or shoulder area. if your attacks are becoming more frequent, it is best if you consult with a doctor, preferably a general surgeon or a gastroenterologist, for complete physical examination and clinical evaluation. diagnostics (such as ultrasound, ERCP, blood exams, etc) will be recommended as needed. management (medical and surgical) will be directed accordingly. definitive treatment for gallstones is cholecystecomy or surgical removal of your gallbladder along with the stones. it could be done laparoscopically (goldstandard) or thru open technique. in your case, it is better to have it done as an elective or scheduled cholecystectomy (not as an emergent case but with urgency in terms of management), for lesser complications and better post-operative course. low fat diet is also recommended. hope this helps. good day!! ~dr.kaye
