TV presenter Sinead Desmond had to be rescued by a helicopter from the top of Mont Blanc after suffering from altitude sickness.

According to The Herald, the 'Ireland AM' presenter (36), who had a brain haemorrhage last year, had to be airlifted off western Europe's highest mountain over the weekend after she was struck down with a bout of the potentially fatal condition.

However, she is adamant that her reaction had nothing to do with her previous medical history and it was "just one of those things".

The star explained to The Hearld how she was "gutted" that she had to be immediately brought down, on the advice of medics, before she could complete the gruelling challenge.

"I was at about 4,000m and I just kind of collapsed - it felt like my head was going to explode," she explained.

"I only had about 800m left to go but there was no way I could go any further. My guide was like 'we've got to get you down' and called the helicopter. I was brought to the hospital in Chamonix and the annoying thing was, I felt fine about two hours later. I was kind of like 'get me back up there!' but they told me there was no way.

And Sinead, who had her first day back at work on Monday, is adamant that her previous medical condition had nothing to do with her extreme reaction.

Last year, she had to be rushed to hospital after collapsing from a suspected brain haemorrhage while filming the TV3 morning show.

She subsequently spent months recovering from her ordeal after being warned by doctors that she needed to take it easy for a while and not overdo things.

She had set herself the challenge to raise funds for Our Lady's Hospital in Crumlin.
