I usually eat dinner early say at 7: 30-8: 0pm and daily I get up at morning say at6: 30-7am. Many times I feel my stomach like a balloon full of gas and I get a pressure which makes me fart or go to toilet. Due to this I can not sleep long in the morning as I get a pressure right at 7 am. So I need to know why is this happening, what do you say this in your medical term and what should be done to avoid it.
