You may well wonder 'why do I have so much gas', but realistically you probably passing about the same as everyone else, although it may well feel like more than this. Most people pass wind, either in the form of burping or flatulence via the rectum, about 14 times per day. This equates to between 1 - 3 pints of gas per person. Most of the gas produced in the body has no smell. When flatulence does smell, this is due to small amounts of sulphur being released by certain bacteria in the large intestine.
What are the causes of gas?
Internal gas is caused in 2 ways, either by being swallowed, or by digestive processes in your intestines.
Air that is swallowed will go down into the stomach, it will then be excreted by burping. A small amount enters the small intestine where it is then absorbed into the blood stream and excreted in other ways. If you chew gum, smoke or eat too quickly then this may well be the answer to your question of 'why do I have so much gas.'
There are certain foods which cannot be digested in the small intestine and are passed through to the large intestine. Here it is more likely that these foods will cause gas as the enzymes work to break them down. The type of foods which cause gas are the following:
Soluble fiber
Sugars
Starches
Carbohydrates
Fats and proteins do not cause gas as they break down. When gas is formed in the large intestine, it is passed out of the body as flatulence.
Whilst not everybody is affected by certain foods in the same way, if you eat a lot of these types of foods it can be a reason to 'why do I have so much gas?'
