Sorry if I've posted in the wrong place but I need clarification. I had an endoscopy today to test for coeliac disease and had to fast for 6 hours. I was told I still had food in my stomach despite this, so they're on about changing my medication. Does Metformin aid digestion then and what are they likely to do? Thanks for any help.
