She broke down in tears in a gym in Melbourne but still made the quarterfinals of the Australian Open.

“That was the last bit of myself I had,” she said.

At the Billie Jean King Cup in September of 2025, Navarro found herself in tears on court during a match.

She said she was “devastated to be representing my country in this state of exhaustion and hunger and confusion, and not being able to properly honor our flag.”

Figuring it out 

Finally, in November of 2025, Navarro decided to meet with doctors, nutritionists and specialists to get to the bottom of what was happening to her.  

“I … made it my mission to be transparent about my symptoms and fix whatever was going on,” she said. 

The diagnosis: “We figured out that I had been under-fueling for almost three years,” she said. “My body was fighting back any way it knew how. It had been screaming at me for years, and I ignored it.”

Navarro committed then to doing what it took to recover. 

“I knew the road ahead wasn’t going to be easy,” she said.

Her regimen now includes changes in diet and increases in energy intake, blood draws and medical prescriptions, monitoring blood sugar and keeping track of symptoms, and appointments with doctors and specialists.  

Her results on court did not improve right away. At the start of the 2026 season, Navarro lost eight of 10 matches before deciding to take some time off and skip the Charleston tournament in April.

But by the time she returned to the Tour over the summer, there were promising signs. She won a clay-court tournament in Strasbourg, made the finals on grass in Nottingham and then the quarters on hard courts at the U.S. Open. She’s currently ranked No. 24. 

The dizziness and headaches have subsided, and she can sleep through the night again. Navarro said she feels comfortable in the gym again and more comfortable with herself.

“So yeah, I gained some weight this year,” she said. “But I also gained my life back. I have enough energy to seize every day, to train or compete as hard as I want to, and to live a life outside of tennis. To laugh, to be curious, to be spontaneous, to spend time with the people I care about, to feel joy, hope and positivity, and to appreciate the incredible gift of life.”
