What Are the Causes of Belching in the Morning?

Belching in the morning may be induced by many factors that vary from person to person. Common causes of burping in the morning might include mouth breathing, swallowed air, food or drink intolerance, and stress. More than one factor can be responsible for excessive belching.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

Mouth Breathing

People who are considered “mouth breathers” might experience an abundance of belches, particularly in the morning time. Breathing in through the mouth while sleeping can cause air buildup or pressure that is released by burping.

Swallowed Air

Swallowing air is common when foods or beverages are consumed too rapidly. Any swallowed air is naturally expelled from the body by burping. Eating or drinking late at night may lead to increased belching.


Consuming carbonated beverages, especially early in the morning or late at night, might be a leading factor. Belching due to carbonation may be accompanied by heartburn or acid reflux.


For some, gulping air to soothe a dry throat or mouth is a natural response to anxiety or nervous energy. This likewise leads to stored up air that is released by belching.

Additional Causes

Some other causes for belching in the morning time may include diet, low stomach acid, chewing gum and airy foods. Limiting one’s exposure to these factors may help decrease excess belching.
