<s>[INST] I have been diagnosed with acid reflux due to hiatal hernia. Recently I have had discomfort in the upper right abdomen and across the middle of my back. Also reflux has flared up again. Taking Omeprazole 20mg for the reflux. Do I have gall bladder issues also? [/INST] hi.noted history of right upper abdomen pain. yes, it is possible that it may be caused by a gallbladder/liver/biliary tree pathology. other things that must be ruled-out are pulmonary and muscular problems. it is best if you consult with a doctor for physical examination and clinical evaluation. diagnostics (such as ultrasound, alkaline phosphatase, liver function tests) and management (medical and/or surgical if indications are found) will be directed accordingly. if it is indeed a gallbladder stone, a low fat diet is also recommended.hope this helps.good day!!~dr.kaye </s>
