Since May I Have Been Experiencing The Need To Go

since may i have been experiencing the need to go to the toilet quite soon after eating.in the past few weeks it is now a case of not feeling empty after i have gone to the toilet and this can go on for a couple of hours until i feel i can then go on with my everyday tasks.i have noticed blood aswell not all the time but on occassions. the stools can vary from small thin pieces to normal pieces. diarroh is common alot of the time. i have been taking some peppermint tablets which do help sometimes.
