Hi welcome to the health care magic For giving more comment I need to know which investigations has been done... USG abdomen done as preliminary work up Then endoscopy examination done If needed and if any ulcer or suspected area present, biopsy taken... Rule out h. Pylori by urea breath test If you are having stress type personality then also such chronic gastric issue can be present According to cause further specific treatment given Avoid gastric irritants like excess spicy foods, smoking, stress, fried non veg etc.. Green leafy vegetables and fruits taken more Hope your concern solved Take care Consult gastroenterologist for examination and further work up accordingly
