1. An intragastric volume-occupying device, comprising:
an intragastric balloon having a wall and a lumen; and
a paste or solution of methylene blue dotted or printed onto at least a portion of an interior of the wall of the instragastric balloon, wherein the methylene blue is configured to indicate a failure of the intragastric volume-occupying device by being reduced to leukomethylene blue upon exposure to gastric fluids, so as to yield a discolored urine as an indicator of failure of the intragastric volume-occupying device.
