Could you print a medical diagram off the Internet when you travel? When the friskers don't know what a stoma, ostomy bag, etc, is, you show them the picture. Some people need visuals! I had to do that when a healthcare person had no clue what a j pouch is; she kept thinking it was an ostomy bag just because I said "j pouch". Mind you, if the friskers looked right at your stoma and still were slow-thinkers, a diagram be beyond them.
