Hi Neerja, Thanks for writing your query. Gastritis result due to increased acid secretion in the stomach. It can result in faulty lifestyle and dietary habbits. You should follow some precautions like :- 1. Avoid spicy/oily foods. 2. Avoid mental/emotional stress. 3. Donot miss a meal. 4. Avoid cigarette/alcohol. 5. Donot self medicate especially with pain killers and steroids. Try to take adequate rest. If you are doing night shifts, you should try to take 6-8 hours sleep in your day time. You can take antacid like Omeprazole 20 mg along with Domperidone 10 mg once a day in morning. Taking antacid in gel form is also beneficial as it forms a protective layer over the damaged mucosa in the stomach. You should take medicines under medical supervision only. I hope this is helpful to you. Thanks.
