Hello Doctor, My brother (27 years old, male) has been experiencing excessive burping, especially after dinner, for the last few months. Burping happens repeatedly one after another, sometimes more than 50–100 times in the evening. There is no severe stomach pain, burning sensation, or vomiting. Appetite is mostly normal. Please advise possible causes (like gas, indigestion, GERD, H. pylori, or gut motility issues), required tests, and treatment options. Also suggest diet or lifestyle changes if needed.
