I recently had an increase in symptoms and tried to explain where I may have been infected by something in my environment, after testing a few ideas I considered the water supply so I tested it by finally switching over to a filtered water from It was a glacier water dispenser at my local grocery store which claims to be irradiated with an ultraviolet light and therefore has no bacteria or other organisms in it. After switching to supposedly bacteria free water all the increased ibd symptoms have now decreased to where they were before. Give it a shot.
