I am taking enema since last 3 weeks. In the first two weeks I was feeling better but in last few days my bowel movement increases and also there is urgency. Today again I saw some blood. I am taking the enema at my bedtime and occasionally some of the vitamin is coming out in the morning with my stool. Is that common? I am on diet. I am a vegetarian so I am only taking vegetables with little oil. I am also taking brown rice. I don't understand where I am doing wrong or it is common that in every now and then blood will come? Please advice.
