I haven't had a blockage. However, since my LC began (11 months ago), I have experienced gastroparesis and constipation to the point of being nauseous. I began drinking prune juice every other day and eating 4 or 5 prunes warmed in a little water on the days in between the juice. It's working (sometimes too well) and I adjust my intake accordingly. I also started eating plain greek yogurt with honey, strawberries or blueberries to try to get my GI tract back to normal. It seems to be helping. I have to be very cautious of what I eat.
