Am hungry in morning. i eat breakfast but still am hungry and also get an urge to poop ,discomfort and pain in stomach after sometime?

This requires a lot of additional info: What and when do you eat at at night? What do you have for breakfast? Are you of normal weight, underweight or overweight? Is this a change in your bowel movements? Is there blood or mucus in your stools? Have you been losing weight unexpectedly? Make an appointment with your doctor and have that information available which will help find the answer.
