I wake up bloated, all day remain bloated and go to sleep bloated. i am always burping. i've went to gluten free diet and no dairy. still there is no change. what should i do?

Maybe that's not it: Make a diet diary for a few days, with symptoms, and go see md. Could be lots of things.

Motility disorder: This could represent a motility disorder. Once structural causes are ruled out, you may want to consider a gastric emptying study.

Try other stuff: Consider taking probiotics. Digestive enzymes or betaine hcl or apple cider vinegar in water with meals may help.
