Kanye West is 'battling health issues.'
A source told People on Friday that he needs to be back to fully well and fit before he will get the all-clear to work again.
'Fitness - physical and mental - are essential to him being able to be restored fully and cleared to work,' the source said, adding: 'He has health issues that need to be resolved prior to returning to work.'

Another source told the publication that the rapper’s impulsive behavior and fluctuating moods that have made it difficult to solidify future plans of any kind.
'He is mercurial. One minute he is here. One minute he is there. He is very very difficult to pin down. Things are changing minute to minute,' the source told them.
A month after canceling the remaining North American dates of his Saint Pablo Tour, it was revealed earlier this week that Kanye will not be moving forward with European shows.

TMZ claimed the 39-year-old rapper has pulled out of the European dates of the concerts after he was rushed to UCLA Medical Center last month for an apparent breakdown.
Sources tell the site that Kanye's psychiatric hospitalisation cut short the 2017 side of the tour, which was set to feature dates in Paris, UK and Germany.
The site reported that Kanye's camp contacted concert promoter Live Nation to explain that the second leg of the tour would not go ahead.

The shock move is set to cause few problems as no dates had been confirmed nor tickets sold, so refunds and rearrangements are not necessary.
News of the tour comes after it was claimed that hospital staff were 'hunting' for his medical information.
According to TMZ, they were 'curious' when the rapper was admitted and tried to gain access to the computer system - reportedly leading to 'several dozen' staff members being fired.
Sources have alleged that the hospital has launched an investigation, while others claim 'several dozen people' have been or will be fired.

Kanye was hospitalised on November 21 after a series of bizarre incidents.
He had been taking part in a gym session at the West Hollywood home of trainer Harley Pasternak when he became agitated and allegedly began screaming that people were trying to kill him.
Dr Michael Farzam was called to the scene and West was placed on a 5150 hold, which allows a physician to forcibly admit a patient to hospital, before being taken to the UCLA Medical Center.
West is said to have been handcuffed to a gurney during the journey, which came two days after he launched a bizarre rant on stage in Sacramento, California, and 24 hours after he announced that he was canceling all remaining dates on his Life of Pablo tour.
He and wife Kim Kardashian are thought to have been arguing a lot in the run-up to his meltdown, while the armed robbery on her in Paris on October 2 is also believed to have contributed.
