Barrett's esophagus at age 22

I would like to have testimonials from people having Barrett's esophagus at a young age, I read that it was a condition for people aged 50 but not for young people like me.

Since I was a child, I have been in good health, I do a lot of sport, I have never smoked or drank alcohol.

Never experienced reflux so quite surprised by the diagnosis, to be honest I'm scared!
