Hi thanks for contacting HCM.... As you have symptoms since two month , following can be diagnosis in your case..... -chronic gastritis -gastric mass -chronic constipation Here first you have to investigate with USG abdomen.. If suspician finding then CT scan like higher investigation needed.... If mass present then biopsy should done to rule out nature of mass... If still cause not clear h.pylori ruled out by urea breath test... For constipation more water needed with fiber foods.... If still cause not clear then antibiotic given for few days to clear bacterial infection... And if still need investigation done finally by endoscopy with biopsy..... Blueberries rich in fiber and vitamin c ...with antioxidant property .so good to take.... Keeping this in mind consult doc.... Take care. Dr.Parth
