Overview
- During the Wimbledon final on Sunday, Alexander Zverev checked a courtside phone tied to his continuous glucose monitor and gave himself an insulin injection between sets.
- Wimbledon and other Grand Slams maintain medical-exemption lists that let diabetic players use phones and receive on-court treatment, and Zverev says one of his phones has no SIM card and is dedicated to monitor readings.
- Zverev reported a dangerous sensor malfunction at the Halle warmup in June that showed falsely high glucose, led him to inject too much insulin, and forced him to consume about 350 grams of sugar to recover.
- Zverev publicly disclosed his Type 1 diabetes in 2022, launched the Alexander Zverev Foundation to help children with the condition, and won the French Open in June while managing his care on tour.
- The episode underlines a trade-off between athlete safety and competition rules and could prompt closer scrutiny of continuous glucose monitor reliability and tournament medical-exemption procedures.
