Air that accumulates in the stomach will usually cause discomfort and pain in that area because the formation of gas will increase the pressure in the stomach area, which in turn causes pain in the stomach. Gas production in the stomach is a normal occurrence. In fact, everyone produces gas in their stomach. However, the process of expelling gas as much as 15 to 20 times a day is able to reduce the gas content in the stomach. The habit of holding gas can cause it to be trapped, leading to severe pain and bloating, leading to discomfort.

In summary, there are two factors leading to accumulation of gas in the body, namely:
1.	Respiration 
2.	Digestion of sugary foods and carbohydrates

The main key to overcome accumulation of gas is through the process of reducing the gas that was produced through the digestion process in the intestines and stomach. Foods that contain carbohydrates and sugar will take a long time to be digested by the stomach and small intestine. Therefore, the digestion process of sugary and carbohydrate-containing foods is likely to be incomplete when it enters the large intestine.
Large intestine is the 'home' to millions of good bacteria (probiotics) that will work to break down sugar and carbohydrate molecules that cannot be digested by the stomach. However, the digestion process that occurs in the large intestine will produce a huge number of gases (nitrogen, carbon dioxide and methane). If ones are unable to expel gas from the large intestine through the process of flatulence or belching, more gas will be trapped in the digestive system causing the stomach to feel sick and bloated.
