Food problem to digest or stool pass out

Hello sir, My name is Mohit. I have a problem of stomach. When I eating food then it goes to stomach and after in intestine to digest but after the going in small intestine to digest and after going in large intestine. It reaches in large intestine but not reach at the anus to excretion. It reches in large intestin.It comes to the border of large intestine, but then he does not descend under it while I drink very hot water.When my food is not passed, I have to take a medicine so that it dilutes the food completely like diarrhea.And if I do not have that medicine, then I do not get potty or pressure for 3-3 days.Because of this I don't feel hungry and can't eat anything then feel heavy.Then there is a lot of stress and then there is no mind.When my food reaches the large intestine but it does not reach below it, I feel that there is an obstruction in the intestine below me Or the part of my bottom intestine has become narrow, meaning that the face of the pipe has come close.What I do.
