I have acidity n gas problem then what i do for clear this problem?

Doctor can evaluate: If there is a stomach acidity problem, the doctor will want to know how badly a person is affected, what treatments have worked for it, whether or not there are pre-cancerous or cancerous disorders, etc... Usually, the first things done are to test for h. Pylori infection, and to start acid blockers such as Nexium or aciphex (rabeprazole). Dietary changes can be helpful, as well as some lifestyle changes.
