Is it normal to burp a lot even when u haven't been drinking anything or eating anything and sometimes they follow by hiccups?

Burping. Burping just means air is coming up from your stomach. If you burp frequently, most likely you are swallowing air when you eat quickly, drinking lots of carbonated drinks, or have a hiatal hernia. Try taking mylanta plus -- with simethecone. If you have any difficulty swallowing or continue to burp frequently, go see your primary healthcare provider.
