Detailed Answer:
Hi sir as you digest food, digestive gases are formed as a result of fermentation and digestion of food which can also collect. Either method can cause flatulence.

The pathophysiology of gas and flatulence is complicated.
The term gut microflora or microbiota means hundeds of species of bacteria which lives in our intestinal tractintestinal tract.These bacterias and yeast are responsible for proper digestion and fermentation of food. Hundereds of species of bacteria and yeast re found in colon of human intestine.In the same way thousands of these species florishes in our gut these bacteria play a vital role in digestuio and absorption of food.Even minor disturbances in gut microflora can lead to significant changes in gut function, including gas production.
There are various mechanism that can be related to increased flatulence
