Talk to General Physician on Gastro Issue

I feel mild pain in my lower abdominal area after having any food or any liquid other than water. After eating or drinking something, it feels like that i need to go to the bathroom but then i go to bathroom sometimes just gas releases out and no stool at all and sometimes even gas doesn't release out. If gas is released out then i feel a bit relaxed. I've been stooling 2 times a day, Once after waking up in the morning and then after having my breakfast. Other than that, no stool at all. What could be the reason?
