Thank you for your response! I am new to this group and it helped a lot. We are very frustrated and I know my son is.

Another issue he has is eating - A LOT! He is a 16 year old boy and they usually eat a lot but he doesn't remember that he ate so always wants to eat again. Could this be related to the bowel movement issue?

He has always been a big eater. He has definitely gained weight - he is 6'2 - 220 pounds. Before his accident he weighed 185 and was 6 ft. He grew when he was in the hospital.

We are going to the doc tomorrow for a follow up. I will discuss these issues with him. I really think this is a brain signal thing (I don't know the proper terms).
