Overview
- Alexander Zverev injected a dose of insulin on court during the men’s Wimbledon final on Sunday to manage his Type 1 diabetes.
- Wimbledon officials say Zverev has a medical exemption that lets him use a phone on court to read a continuous glucose monitor instead of doing finger‑prick tests.
- At a Halle warmup in June a sensor gave a falsely high reading, which led Zverev to inject too much insulin and then consume about 350 grams of sugar during the match to correct his levels.
- Zverev told reporters he has used glucose sensors for more than a decade and that the device maker is investigating the Halle malfunction to determine what went wrong.
- Zverev has made his condition public since 2022 and launched a foundation to help children with diabetes, and his visibility may prompt closer review of sensor safety and tournament medical rules.
