Hello There,
If Burping problem is since 2-3 weeks only then no need to worry much. It might be due to Hyperacidity and Gas problem. First of all avoid all Fatty and Fried food. Avoid aerated Drinks strictly. Follow strict meal time scedule everyday. Meal scedule should not be missed and its better to have small meal 4 times a day.
Next Steps
You may start one "Capsule Pan-D" everyday. Take it in empty stomach early in the morning and then have something after 30 minutes. If does not get relief after a week then visit to your nearest Physician.
