"You're never going to race again."
That's what doctors told Ryan Reed after his blood work came back. The 17-year-old had been diagnosed with Type One diabetes, which can be deadly.
Reed had been racing since he was a toddler and was on the brink of breaking into NASCAR.
"At that point, you know, a doctor tells you your career is over," Reed told CNBC. "I didn't know what to do."
After wrestling with the news, the teenager realized that before giving up, he needed to try everything that he could. He researched the disease and stories of athletes with diabetes, and he found the right doctors to help him.
Just two year later, Reed made his first professional start with NASCAR at age 19. Today is a driver for Roush Fenway Racing in the NASCAR XFINITY Series.
