As a 22-year-old on the Giants A-ball club, Adam Duvall was hoping to achieve his dream of advancing to the majors without any setbacks. But then a lingering health concern changed the plan. Duvall had lost 20 pounds over the course of the season as the symptoms of Type 1 diabetes took hold. Although the Louisville, Ky., native was diagnosed as a pre-diabetic during his childhood, he and his parents didn’t worry because the condition was manageable even while playing sports. “Being a young, healthy athlete, I didn’t think, ‘Gee, I need to worry about that,’” Duvall said. “But I would go low (on insulin) during games, and I would always have a payday (reaction). During the games when I was younger, I’d be jittery.” Once the team’s doctors confirmed the diagnosis, Duvall had to mentally adjust to the unanticipated setback. It would take work, even more than what's normally required to reach the majors, but Duvall was committed to keeping the disease in check so he would one day reach his goal of being a big-leaguer. That day came when he debuted with the Giants in 2014. Since then, Duvall has continued to elevate his game, and, now with the Reds, is putting up All-Star numbers. But managing his diabetes remains a priority. Men with Type 1 diabetes lose around 11 years of their longevity in contrast to those without it, according to recent studies. Duvall could feel the effects of the disease on the field during that first season in the minors. Fatigue was common when his blood sugar wasn't right. Long bus rides and a lack of sleep didn't help. Staying vigilant wasn't always easy.
