- Emma Navarro was diagnosed toward the end of 2025 with relative energy deficiency in sport (RED-S) and the autoimmune disorder Hashimoto's hypothyroidism, conditions she said caused "headaches, dizziness, brain fog, fatigue, anxiousness and mood swings" through 2025
- Navarro lost approximately 14kg in weight during 2023 and 2024 while experiencing what she described as "deep internal anger" on court — including at her breakthrough WTA Tour victory at the Hobart International — and said she was hungry "every hour of the day"
- Navarro lost 9 of her first 13 matches in 2026 and withdrew from the Charleston Open at the end of March, having previously reached a career-high ranking of No. 8 in 2024 after quarter-finals at the Australian Open and Wimbledon and a semi-final at the US Open
- The 25-year-old won the Strasbourg Open in May — her first title in more than a year — and is currently ranked 24th in the world
- Navarro wrote in a lengthy Instagram post that she had been "under-fueling for almost the entire period" despite appearing "the strongest, fittest version of myself I had ever been" to outside observers, and ignored warning signs because pushing herself "was always my MO"
- Navarro is skipping the Asian swing to complete her recovery and plans to return next season, stating: "I gained some weight this year. But I also gained my life back"
Why it matters: Navarro's diagnosis recasts her 2024–2025 results in a new light — her career-best season and ranking rise to No. 8 came while she was unknowingly under-fueling, and her post-diagnosis Strasbourg title suggests the recovery is translating back to results, though her ranking has dropped to 24th.
