Hi thanks for contacting HCM... Noted you had gastritis and now you have second time it... You are taking pentoprazole ...So take it for 2 week. It will help in healing of ulcer or gastritis... Meanwhile avoid irritants that contribute in gastritis..... -tea excess -excess coffee -alcohol -smoking -non veg food etc... Fruits more and green leafy veg useful... Avoid stress.... Frequent sip of hot water help in upset stomach. Peaches that are rich in fiber, vitamin c , pottasium , calcium etc...help in good digestion ... Oat meal rich in selenium , fiber, vitamin e etc..so soothing effect ..good to take ... If still no benefit then investigate for h.pylori by urea breath test... If still need investigation then endoscopy done to investigate further with biopsy to rule out autoimmune problem , non specific gastritis or viral infection like herpes or cytomegalovirus... Keeping these in mind consult doc.... Dr.Parth
