Bevarage Burps - It's the fizz. Soda, beer and all the other bubbly drinks are made with a gas ccalled carbon dioxide. This adds extra air in your stomach, which finds its way back up the same way it entered: through your mouth.

Ulcers - Sometimes, burping can be a sign of stomach ulcers. These open sores in the lining of your stomach are quite common. Ulcers can be caused by an infection or by taking too many NSAID's. If you have an ulcer, you may burp more and feel full or bloated after eating fatty foods. With treatment, ulcers can clear up within 2 months.

Lactose Intolerance - Many people lack the protein that breaks down the lactose in milk. This means that your gut can't fully digest foods that contain dairy. Instead, the lactose ferments in your stomach creating extra gas.

Acid Reflux - Sometimes, stomach acid backs up into your throat. This is more likely to happen if you're pregnant, obese, or your stomach doesn't digest food as fast as it should. Once you feel this lump in your throat, you'll swallow more to try to get rid of it. This can make your burp.

Asthma - Strangely, burping can be a sign of asthma. If your airways are inflamed, you have to work harder to get enough air into your lungs. This also puts extra pressure on your diaphragm. Bothof these changes can force gas into your throat and make you burp.
