The country's most successful current performer underwent surgery earlier this year to remove his gall bladder and appendix.
Avicii — who turned 25 on Monday — has called off all shows "until further notice so he can fully recuperate from lingering health issues" linked to his operations, according to a statement from his management.
The electronica star is resting "so he can regain his strength and physical well-being before the release of a new album project next year," the statement added.
Avicii had planned to headline next month's Storm Festival in Shanghai, the second edition of the concert aimed at tapping a rising Chinese demand for electronic music.
The DJ had also planned five shows in Las Vegas, two performances in Japan and was due to play TomorrowWorld, the US spinoff of Belgium's TomorrowLand dance festival, which takes place later this month near Atlanta.
Avicii, whose real name is Tim Bergling, scored an international hit last year with his track "Wake Me Up," featuring the voice of the American R&B singer Aloe Blacc.
