Trapped Wind / Trapped Gas
Trapped wind or more correctly, trapped gas, can be just an embarrassing condition, but it can also be painful and/or an indication of another underlying gastrointestinal problem.
Trapped wind is a build-up of gas in your stomach and lower intestines. Although it is natural for your digestive systems to produce gas, the problem starts when this gas gets trapped and is not expelled naturally.
The main source of trapped wind is carbon dioxide which is produced naturally by chemical reactions in the intestines.
Our gut contains gas because we swallow air when we swallow saliva, food and drink. The saliva contains bicarbonate which reacts with stomach acid, producing carbon dioxide gas. Approximately 500 types of bacteria live in our intestines. These act on food, releasing hydrogen, methane and carbon dioxide gas.
Some of the intestinal gas is absorbed into the bloodstream and is eventually exhaled via the lungs. Because of social considerations we hold gas in so more passes into the bloodstream and then to the lungs. The result is that in social situations our breath contains an increased amount of hydrogen gas.
The greatest part of intestinal gas is gotten rid of by breaking wind, belching and flatulence.
