it's probably a simple reaction between the water and your stomach acid. i can think of a number of chemical reactions that could cause you to experience gas after drinking water even though it's not terribly common for most people. at any rate you need to stay hydrated. you can try drinking water more slowly to see if it causes the same reaction. or you can try drinking water with some sort of sugarless flavoring added. or you can obtain hydration by eating fresh fruits such as berries and melons. if the problem continues to annoy you you might consider checking with your health care provider about it. hope this helps!
