Thank you very much for contacting healthcare magic. You have problem of burping that may be because of too fast eating or drinking habits. More amount of chew a chew gum cause excessive air entrapment. Carbonated beverage and smoking cause burping problem. Gastroesophageal reflux disease may ruled out. Gastritis may cause burning problems. Improper denture fitting may cause air entrapment at eating time. Consent a gastroenterologist for further treatment. Abdominal ultrasound sonography is helpful for diagnose. Abdominal barium x ray can done for further diagnosis. I hope my guidance is helpful to you. Thanks
