Hi i m 26 year old . i have gass problem and some time i feel pain top of my stomach .

Bloating : It looks like you have bloating problem that causes stomach upset. The most common cause is lactose intolerance due to lacking of lactase to digest lactose, a form of sugar found in dairy products. You can try taking off milk and all dairy products for a week. If that is the cause, bloating will go away within a few days. If not, see a doctor to look for other causes like gluten sensitivity, ibs..
