Eat slowly to reduce the amount of air you swallow. Avoid
eating on the go. Try sitting down at a table for your main meals and avoid
eating while watching TV or on your computer. Distraction tends to make us eat
faster.
Some people burp 10-20 times a day and usually there is
nothing to worry about provided your burps are just burps – no discomfort, no
reflux, no bloating or other symptoms (and you are not embarrassed by your
burps).
Every day our body produces 25 litres of gas in the
intestine. Thankfully most of this is re-absorbed and only about one to two
litres is expelled from the body by either burping or flatulence. Burping is
how our body gets rid of excessive gas from the stomach. Gas further down the
intestine will be released as flatulence.
Most of the time our burps are caused by simply swallowing
too much air while we are eating or drinking. Certain foods or food
intolerances may result in burping and occasionally a medical condition
requiring investigation and treatment is the cause of burping.
Swallowing too much air
It is normal to swallow some air when we eat and drink,
however when we eat quickly and drink large volumes of liquid, this increases
the amount of air that we swallow. Excessive air in the stomach causes it to
stretch and burping is the easiest way to get rid of the excess air. Other causes
of excessive air in the stomach include chewing gum, sucking on hard lollies,
talking while eating and smoking.
Foods that cause too much gas
Certain foods are known to cause excessive gas in the
stomach because they produce gas during the digestive process. Cabbage, onions,
broccoli, cauliflower and lentils are often the culprits.
Food intolerances are another reason for excessive burping.
If your body has trouble digesting foods, you may get an increase in gas. Common
examples are lactose intolerance or gluten intolerance. If you suspect your
burping is linked to certain foods, keep a food diary and then discuss your
symptoms with your doctor or a dietitian before eliminating foods.
Medical conditions that cause burping
While most of the time our burping is harmless, there are
several medical conditions to look out for. Refluxing food from the stomach
back up into the oesophagus is a common cause of burping. Other conditions include
a hiatus hernia – when part of the stomach has moved up into the chest cavity.
Stomach ulcers and bacterial infections of gut can also be the underlying cause
of your burping.
When to see your doctor
If you are worried or embarrassed by your burping, have a
talk with your GP. Symptoms that should be investigated include: abdominal or
chest discomfort, nausea, bloating, unexplained weight loss, vomiting,
difficulty swallowing or feeling overly full after eating.
