Surgeon Mr Singh is Dr Hilary's Health Star

On Monday we launched our Good Morning Britain Health Star awards to reward those who have gone that extra mile to help someone's health or save a life.

All week we have been meeting our presenters' own Health Stars, and today we meet Dr Hilary's - Mr Singh, the surgeon at Birmingham Children's Hospital who operated on his granddaughter Bella when she was very ill.

Ben Shephard's emotional Health Star nomination

It was an emotional moment when Ben Shephard was asked to reveal his Health Star as part of our new campaign.

Ben fought back tears as he nominated his health hero Mr Asif Hasan, a surgeon at the Freeman Hospital in Newcastle, who helped to save the life of his best friend's son, Sebastian.

Sebastian was born with a potentially fatal heart condition and had to have life-saving surgery when he was just four months old. He was told he would only live until he was two, but in January Seb celebrated his seventh birthday.

We caught up with little Seb and his parents Ivan and Nadine Hollingsworth who set up a charity to show their gratitude to the children's heart ward.

Nominate your GMB Health Stars

Do you know someone who is a health star ?

Good Morning Britain's Health Star awards recognise the best of British healthcare, and if you know someone who has gone above and beyond to help someone we want to hear about it.

You could nominate a hospital consultant, junior doctor, mental health practitioner, GP, community nurse or just an ordinary member of the public.

The three categories viewers can nominate in are:

  • Hospital Health Star - anyone who works or volunteers in a hospital in the UK, Channel Islands or Isle of Man
  • Lifesaver Health Star - a professional or member of the public, who has saved someone's life
  • Community Health Star - anyone who works in the health service or local community

Study reveals more than half of child asthma cases may be misdiagnosed

A new study suggests that child asthma is being over-diagnosed by doctors - more than half of those told they have the condition may not actually have it.

Dr Hilary looks at the results of University Medical Centre Utrecht's study into the respiratory condition, which indicated doctors were failing to properly assess youngsters or carry out appropriate lung function tests.

Know the symptoms of meningitis

Over 300,000 signatures now back a campaign to give meningitis vaccines to all children.

It comes after mum Jenny Burdett shared a heartbreaking picture of her two-year-old daughter Faye, who died from meningitis on Valentine's Day.

Former England rugby union captain Matt Dawson then revealed that his toddler son survived meningitis after "two weeks of hell", shared his own shocking images on Twitter, charting his child's recovery.

Watch the video above for Dr Hilary telling us the symptoms we shouldn't ignore.

Patients in remission after cancer breakthrough

It is really exciting

– Dr Hilary Jones

Patients who were told there was no hope are now living symptom-free after their own bodies were trained to beat cancer.

A potentially revolutionary therapy by American scientists that trains the immune system to attack cancer has shown "extraordinary" results in early trials involving terminally ill patients.

In one study 94 percent of participants with acute lymphoblastic leukaemia saw their symptoms vanish completely.

Trials on blood cancers also had over 80 percent success, with over half of patients in remission.

Dr Hilary Jones joins us to tell us more.
