Djokovic Crashes Out in US Open Round 1, Vomiting Through 5-Set Loss

Q: After a dramatic physical collapse, what undisclosed chronic illness might finally force the 39-year-old tennis legend into permanent retirement?

It is not publicly known. Djokovic has disclosed only that he has been dealing with a chronic health condition for “the past couple of years” that causes major problems “especially when it is humid and it is hot,” but he has not named the illness. What is clear from his own comments and the recent evidence is that the condition appears to be severe enough to affect his ability to finish long matches in extreme conditions. In Cincinnati and again at the US Open, he was seen vomiting, cramping, and struggling physically before saying his body had “started to collapse.” That has intensified questions about whether his body can still withstand best-of-five-set Grand Slam tennis at 39. Outside observers have raised possibilities, but no verified diagnosis exists. Former coach Paul Annacone openly asked, “If it’s a chronic illness, what is it?” while Patrick McEnroe suggested it may have looked like a virus worsened by heat, though that was speculation rather than reporting. So the undisclosed illness that might force retirement remains exactly that: undisclosed. The strongest reported takeaway is not the name of the condition, but its apparent impact. Djokovic’s own remarks suggest it is longstanding, heat-sensitive, and increasingly disruptive, making retirement a more realistic possibility if it cannot be managed.

Novak Djokovic said a “serious issue” left him vomiting, cramping and in pain during his 7-6(5) 5-7 4-6 6-2 6-1 first-round loss to Mariano Navone at the US Open.
The 39-year-old struggled throughout the humid night in New York, called for the doctor early, briefly rallied to lead by two sets to one, then broke down physically and in tears.
For Mariano Navone, 25, the win over the fourth seed and world No. 49’s first-round upset ranks among the biggest victories of his career.
The defeat was Djokovic’s first opening-round loss at Flushing Meadows, his first at any Grand Slam since 2006, and ended another bid for a record standalone 25th major title.
