Having gastric problem from past 3-4 months... whatever i eat makes gas in my stomach... what can be the cause? i am always having feeling of fullness

Check your diet: Sometimes a diet full of unhealthy foods can cause this feeling. Too much soda or carbonated beverages can cause the feeling of gas. Sometimes too much dairy (milk products) can cause this feeling as well because of lactose intolerance. Check your diet, make sure to eat healthy clean foods like fruits, veggies, lean meats, healthy grains. Limit processed, sugary, and fatty foods.
