Good advice here, Pete. During x-ray, TSA sometimes scoffs at the dark spot around your mid-section. I travelled a lot for work several years ago and only had to explain what it was to one TSA agent, out of hundreds. She was a young lady and obviously a brand new agent. I casually explained what ‘the dark area’ was. Being introduced to the concept for the first time, I watched her face crinkle up as she was mortified at the thought. She languished a bit, not knowing exactly what to do, so I asked her if she’d like to check it out, at which point she promptly responded, “Um… No thank you.” I laughed a bit and went on my way. It wasn’t a problem. I’m surprised more of them don’t question us but you can imagine that if they’ve been on the job for more than a day, they’ve encountered ostomies. I also imagine TSA training addresses ostomies. Perhaps the young lady dozed off during that lesson. Lol. Either way, don’t worry about it. Have fun on your trip!
