I'm always bloated unless i drink a whole ton of water and then it comes back the next day :(?

Is this a sign of a serious condition? Why is my stomache being like this? This has been going on for over a year and my doctor never helps me :(( and i drink so much water to help it, but i hate drinking so much water because i get discusted and the bloating comes back the next day anyway. What could this be?!!!
