I got curious and decided to do a little research on why we burp and what causes us to need to burp...

From MedMD:

"Belching or burping (eructation) is the voluntary or involuntary, sometimes noisy release of air from the stomach or esophagus through the mouth. Burping 3 to 4 times after eating a meal is normal and is usually caused by swallowing air. Other causes of burping include nervous habits or other medical conditions, such as an ulcer or a gallbladder problem."

And a GREAT list of reason a person might belch from WrongDiagnosis:

"Causes of Belching:
The following medical conditions are some of the possible causes of Belching. There are likely to be other possible causes, so ask your doctor about your symptoms.

Normal infant
Swallowing air
Habitual air swallowing
Mouth breathing (see Breathing symptoms)
Chewing gum
Poorly fitted dentures
Relaxed esophageal sphincter during breathing
Inferior wall myocardial infarction - rarely the cause but may cause belching with chest pain.
Emotional stress
Carbonated beverages
Food intolerances
Food allergy
Milk intolerance
Stomach acid deficiency
Rare belching of true foul-smelling intestional gas rather than swallowed air:
Gut fermentation
Gastroparesis
Vagotomy
Pyloric obstruction
Peptic ulcer
Intestinal tumor
Nervous habit of swallowing air during eating or talking
Gastrointestinal ulcers
Gallbladder disease
Pancreatic disease
Lactose intolerance
Pregnancy
Obesity
Hiatal hernia
Reflux esophagitis
Eating beans
Consumption of dairy
Consumption of certain vegetables - broccoli, cauliflower, corn
Irritable bowel syndrome
Malabsorption "

And this... but you'll have to go there to read it, I can't copy it. It's good and you should read it. It suggests having a Heidelburg test (the one for stomach acid, not dyslexia or your retinas!!) done if you can't figure out what's causing excessive burping.
