Carol Vorderman has opened up on her most recent health battle after falling unconscious and being rushed to the hospital. Taking to Instagram, the 65-year-old former Countdown presenter shared that she had suffered a concussion after tripping over a tree root.

In a clip, where she spoke into the camera, Carol explained how, when she regained consciousness, she struggled to sit up and could not stop vomiting. She was forced to take a social media leave of absence due to bruising on her face and continuing dizziness. The TV personality wrote: "I tripped, unconscious, hospital, concussion, massive dizziness. THIS IS HOW THE DIZZINESS WAS SOLVED QUICKLY. Last day in May, I tripped over a tree root near my house on a public path, stumbled and fell on my head. Was unconscious, ambulance to hospital. My son Cam told me the 'Final Countdown' was playing in the ambulance. Funny."

She went on to explain that her ordeal didn't end there. "Anyway, I was discharged and the next day couldn’t sit up and had massive continual vomiting so straight back to hospital," she said.

"Thank you Bristol Royal Infirmary. CT scans etc. Discharged. Almost half of my face developing black eye and bruising (that’s why I wasn’t doing reels in June!!!) 2/3 weeks later things had settled BUT I was dizzy like I was walking on a moving ship. So what to do?"

Carol shared that she confided in a concussion clinic which treated pro athletes. Expanding on the treatment that she underwent, the TV host said: "Sophie who treated me did lots of tests and thought I was suffering from BBPV which is a disruption in the inner ear (forgive me if I get a bit of the medicine wrong btw I AM NOT A DOCTOR). I think it’s a tiny sack of crystals in the inner ear which gets dislodged and needs to go back together, again excuse my simple explanation.

"She gave me the Epley Technique. Sit upright on the massage bed with legs straight out, look at her with eyes open, she held me and then threw me backwards quite quickly (and safely).

"OMG it felt like I was falling off the edge of the earth !!!! She held me until the feeling passed for a minute or so. Then did the same on the other side."

Carol said that she had undergone three lots of treatment and has now been discharged, claiming that "95%" of her dizziness is gone.

Fans were quick to support her and wish her well in the comments. "Hope you're doing well now," one said as another urged: "Take care."
