To force a huge burp, start by drinking a carbonated beverage like soda or sparkling water, which can help to build up gas pressure in your stomach and help trigger gas release.
Breathing while you're sitting up straight can also help to increase your chances of a huge burp.
And try to get air into your throat by sucking in air through your mouth until you feel an air bubble in your throat.
Then try blocking the front of your mouth with your tongue so you can also release the air slowly, which should trigger a burp.
Another way to trigger or induce a burp is to swallow some air.
You should exhale until your lungs are empty.
Then breathe in deeply and hold it for as long as possible.
And then exhale and inhale again and swallow the air.
To make yourself burp when it's stuck and relieve the stuck gas, try sitting up straight, performing gentle exercises like walking or even doing some Yoga poses.
If these things don't work, you can also try swallowing some air to trigger the burp, or sip on a warm beverage or as a last resort you could try gently stimulating your gag reflex with a finger.
For chronic issues, especially if you're unable to burp at all, see a doctor to rule out any conditions, like Retrograde Cricopharyngeus Dysfunction.
Sitting up straight can also give your abdomen more room and laying on your left side can also help with burping as this position can help to guide gas out of your stomach.
Or even doing gentle physical activity like walking or Yoga can help to move gas through your digestive system.
