Burping

Burping (also called belching and eructation) is the release of <a href="/facts/Gas/hVVAoodV">gas</a> from the upper <a href="/facts/Gastrointestinal_tract/nK2zwqBS">digestive tract</a> (<a href="/facts/Esophagus/XWa7WoWn">esophagus</a> and <a href="/facts/Stomach/Q4PPDGT6">stomach</a>) of animals through the <a href="/facts/Mouth/WthDlXsC">mouth</a>. It is always <a href="/facts/Hearing/EPYrVkSx">audible</a>.
In humans, burping can be caused by normal eating processes, or as a side effect of other medical conditions. There is a range of levels of social acceptance for burping: within certain contexts and cultures, burping is acceptable and may even be perceived as humorous, while in others it is seen as impolite or even offensive and therefore unacceptable.
Humans are not the only animals that burp: it is very common among other mammals. In particular, burping by domesticated ruminants, such as cows or sheep, is a major contributor of <a href="/facts/Methane_emissions/IrclnYfB">methane emissions</a> and may <a href="/facts/Environmental_impact_of_meat_production/quFfEtn4">have a negative effect on the environment</a>. Significant research is being done to find mitigation strategies for ruminant burping, e.g. modifying the animals' diets with <a href="/facts/Asparagopsis_taxiformis/EUKpGeHX">Asparagopsis taxiformis</a> (red <a href="/facts/Seaweed/thLwLBk8">seaweed</a>).
