Only recently, Alexander Zverev revealed that he's been fighting with diabetes since he was four-years-old.
When revealing that he is battling with diabetes, the German also announced the establishment of the Alexander Zverev Foundation to aid individuals affected by the illness. Now, after achieving great sporting success, he feels comfortable discussing his struggle with the condition and that's why he has decided to go public.
"I was always told that I would never make it with diabetes," Zverev said. "Different doctors, different specialists said: 'Competitive athlete with diabetes? That is impossible.' And then at some point I though myself: 'I am second in the world, I am Olympic champion, I can help others with this issue!'"
"I can encourage others, I can be the messenger for the topic of diabetes. And then I thought, I feel good, I am 25-years-old and I want to help other children and especially other parents. I want to show them that everything is possible with diabetes. That's why I made it public."
