Why am i experiencing severe bloating every time that i eat?

Bloating: May be gastritis/ GERD with or without H pylori ( can try ranitidine or prevecid) or may be food intolerances gluten, milk, soy or if drink a lot of soda too much air swallowing while eating. Could try avoiding gluten for a week, then milk, the next week then soy and see if makes any difference . Also may be related to thyroid check TSH. rarely may be autoimmune f/u w/ doc/ gastroenterologist
