Thank you for the query.
Gas and bloating
can be caused by a diet. However, as the most of the gas in digestive tract is produced by bacteria, some mild bacterial infection or lac of good intestinal bacteria can be the reason. This is more probable especially that there is no difference in eaten food type.
That is why I suggest you to start with probiotic
intake. You may add some yoghurt to your diet as well. Try to avoid any sweets like chocolate, carbonated drinks, fatty foods.
If this wont help, stool test
should be done.
Hope this will help. Feel free to ask further questions.
