Kids With Type 1 Diabetes Can Play Sports and Win Big

Tennis star Alexander Zverev has competed at the highest levels of his sport since childhood, all while managing type 1 diabetes diagnosed when he was just four years old. His success shows what's possible when kids with the condition get the right support and information.

Around 2.7 million people in Europe live with type 1 diabetes, the highest rate of any region in the world. Many parents worry their child's diagnosis means giving up sports and physical play.

The reality is completely different. Professor Thanasis Tziamourtas from the University of Thessaly in Greece says kids with type 1 diabetes should follow the same activity guidelines as their peers: 60 minutes of moderate to vigorous exercise daily.

"Type 1 diabetes requires management, but it should not set the limits on a child's dreams," Tziamourtas explains. The condition happens when the immune system destroys cells that produce insulin, the hormone that regulates blood sugar.

Unlike type 2 diabetes, it has nothing to do with diet or exercise habits. Kids need insulin therapy through injections or pumps, but that doesn't mean sitting on the sidelines.

Zverev isn't alone among elite athletes. American swimmer Gary Hall Jr. won 10 Olympic medals, five of them gold, while managing type 1 diabetes. Dutch volleyball star Bas van de Goor also reached Olympic champion status with the condition.

The key is understanding how different activities affect glucose levels. Aerobic exercises like running and swimming can lower blood sugar, while high intensity bursts might temporarily raise it. Every child responds differently based on factors like meal timing, insulin levels, and fitness.

Modern continuous glucose monitoring systems help families track these patterns in real time. Kids should check their glucose before, during, and after activity, and always have fast acting carbohydrates available for low blood sugar episodes.

One important detail: glucose can drop hours after exercise ends, creating a risk of nighttime lows when kids train in the evening. Families learn to watch for this pattern and adjust accordingly.

Why This Inspires

Working with their medical teams, families develop personalized plans that account for the sport, time of day, and the child's unique responses. What works for one kid might not work for another, and that's okay.

The goal isn't avoiding exercise but preparing properly for it. Regular physical activity improves heart health, muscle strength, insulin sensitivity, and body composition in kids with type 1 diabetes, just like it does for everyone else.

Beyond the physical benefits, sports offer something equally important: the confidence that comes from doing exactly what peers without diabetes do. Kids learn they're capable of the same activities, the same competitions, and even the same championship dreams.

Tziamourtas sums up his advice simply: "Exercise, know your body, monitor your glucose and learn to adjust your insulin and your diet correctly." With the right preparation and support, type 1 diabetes becomes something kids manage, not something that manages them.
