Hello I Am Xingli From China And I Moved To

Hello I am Xingli from China and I moved to Austrlia half a year ago. Since I got here I have always been suffering from belly inflation. I thought the reason was I have eaten much more after getting to the new country. But apparently not because when I went back to China to visit I ate even much more but my belly got small. I thought later maybe I am gluten free so I have been having the diet but my belly inflation is back.
