It means inflammation of the colon (large intestine). As you know, waste material rejected by the small intestines, is passed on to the large intestine, the colon.
It is when the colon is quite filled up, that one receives an urge for the motion to relieve himself by defecating. The walls of the colon are protected from inside by a lining of the mucous membrane.
Due to wrong functioning of the system, faecal deposits (excrements) accumulate around the walls of the colon, which cause irritation.
In such a case only liquid food, such as fruit juices, or soup vegetables, is given to the patient, not any solid food, not even roughages, as those would injure the affected walls of the colon. The rest of the treatment is the same as described above for the Colic Pain treatment.
