Alexander Zverev Overcomes Diabetes Challenges To Claim US Open Glory
Alexander Zverev has diabetes, so he needs insulin and must check his blood sugar.
In the past, people often checked blood sugar by pricking a finger.
Now, a small continuous glucose monitor can be placed on the upper arm.
The monitor sends blood sugar readings to a phone.
Zverev had to persuade tournament authorities to let him use this device.
A similar problem happened at the French Open three years ago.
That issue has now been settled.
Zverev has gone on to achieve US Open glory while managing his condition.
Alexander Zverev has diabetes and uses insulin to manage it.
Continuous glucose monitoring lets him track blood sugar through a sensor on his upper arm.
The sensor sends glucose readings to a mobile phone, reducing the need for finger-prick tests.
Zverev previously faced difficulties with authorities over using the monitoring system at tournaments.
The issue also arose at the French Open three years ago but has now been settled, as Zverev celebrates US Open glory.
