Emma Raducanu wraps up her season and plans to retain trainer through next year.
The British player advanced to round three in three out of four major tournaments in the current campaign.
Britain's Emma Raducanu has withdrawn from the last two tournaments in 2025 because of the illness that has affected her for the last week and a half.
The 22-year-old was due to play in events in Asia but opted to return home to recover ahead of launching next year's training.
Her upcoming training are set to feature trainer Francisco Roig, as both individuals have decided to continue collaborating for the upcoming season.
She required blood pressure checks in her opening round with Ann Li in Wuhan and stopped playing when trailing 6-1 4-1 on a day with extreme humidity.
She again required medical attention at the recent Ningbo Open, where she lost in three sets to Chinese wildcard Zhu Lin in the first round.
Her movement was far from freely in the deciding set against Zhu due to the lower back problem that has been a concern at times this year.
These outcomes followed a positive campaign, in which the player advanced into the international top 30 after a long gap for the first time since 2022, concluded with three straight losses.
The athlete was close to victory with three match points before losing to Pegula in round three in last month's Beijing event.
The player achieved 28 matches in the current season and made it to the semi-final round in Washington, but the highlight of her season was at March's Miami Open.
As Britain's top player reached the quarter-finals of a premier WTA event, defeating eighth seed Emma Navarro on the way then falling in three sets to Pegula, ranked fourth.
Her coach was Mark Petchey as coach from the Miami event through Wimbledon, with Roig taking over ahead of the US Open.
The first plan with Rafael Nadal's former coach was through the season's conclusion but the collaboration persists, with planned training sessions late this year.
The athlete revealed that the trial session alongside Roig after Wimbledon was like a "secret mission" as the meeting was kept under wraps.
She nearly succeeded to overcoming Sabalenka, the world number one at their initial event as a team in Cincinnati during August.
Roig joined her in the New York tournament, where she advanced to round three then falling to Rybakina, champion at Wimbledon in 2022.
