The music mogul returned home from hospital on Friday (27 October) afternoon, after being rushed to A&E the same morning.
Following advice from doctors, he then missed both of the first ‘X Factor’ live shows of this year’s series.
Simon has now said that the incident has served as a wake-up call, telling The Sun: “Sometimes we get a reminder that we’re not invincible and this was certainly mine. It was a huge shock.
He’s also detailed what actually happened, stating that he went downstairs to get some hot milk because he felt “ropey” and began to feel dizzy as he returned upstairs.
Simon’s absence was addressed on Saturday’s ‘X Factor’, as Dermot O’Leary reassured fans that despite the fact he was missing from the panel, Simon was on the mend.
On Sunday, Alesha Dixon replaced him. It’s believed that Simon will be back in his usual seat this weekend.
