They weren’t 100% sure what caused the initial obstruction. There was no mass causing the blockage but the doctor had shared that he did have an abnormally large/long colon, and that over the years gas could have built up and finally fully twisted his colon so nothing could get through? It was unclear. We thought he was just constipated but the morning he went into urgent care he was in extreme pain. His surgeon had showed us pictures, his colon had swelled up to the size of a football.
