Team Scotland later said Hawkins had been taken to hospital for treatment, as is normal procedure in such cases, and there were "no major concerns at this stage".
British marathon champion Paula Radcliffe added to the criticism, questioning Commonwealth Games organisers and medical support staff's handling of Hawkins's condition.
According to a report, an official informed the spectators to leave Hawkins unattended.
There are also strict rules around accepting medical help with athletes facing potential disqualification if they are assisted.
Hawkins was left unattended for several minutes, much to the dismay of commentators, reporters and viewers.
Team Scotland's statement continued: "Whilst Callum's recovery is our clear priority, we are still reviewing the circumstances of today's race with GOLDOC and the CGF to ensure the continued health and wellbeing of all athletes remains paramount".
Sports commentator Steve Cram said it was "a disgrace" that it took so long for any paramedics to attend to Hawkins.

Mark Peters, chief executive of Games' organisers GOLDOC, promised to investigate the lack of immediate medical care.
In response GOLDOC confirmed medical staff were posted at 500 metre intervals in the final kilometres of the course with radio communications. "The response of medical staff this morning was inside agreed response suggestions and timeframes", talked about the assertion.
"I was also concerned about the behaviour of a small number of bystanders who chose to take images", he said. "This is not in keeping with the spirit of Gold Coast 2018".
Hawkins was by no means the only athlete to suffer in the heat - Tanzania's Stephano Huche Gwandu was taken away in a wheelchair after taking a tumble as he crossed the finish line.
"I heard he is a bit better so I really hope he's alright".
"Sometimes medical people arrive and the athlete has to make a decision as to whether they want to go on or not".
"I saw him lying there and wanted to stop to see if he was alright. As soon as I used to be coming down the home straight I tried to hurry up, nonetheless I was merely gone". You can not just wait at the finish line - people get in distress further down the course.
There was an anxious wait before any assistance reached the stricken Hawkins, by which time Australia's Michael Shelley was passing the scene on his way to winning gold.
Fellow Tanzanian Saidi Juma Makula collapsed close to the finish line before being helped into an ambulance - one of seven of the 24 starters who failed to complete the race.
Uganda's Munyo Solomon Mutai took silver, whereas Scotland's Robbie Simpson picked up the bronze.
