A gran who had been vomiting every day for a decade became overcome with emotion when her mystery condition was finally diagnosed.

Judy Wilsher would bring up "bright yellow bile" after every meal and was became nothing but "skin and bones" with no clue what was causing her grief.

The 71-year-old was misdiagnosed for years, lost over a stone and a half in weight and underwent a multiple surgeries.

But her life has been dramatically changed after TV sleuths went to work, and her emotion was clear to see.

Judy's tears of happiness came as BBC's Diagnosis Detectives found out why she was suffering so badly, diagnosing her mystery illness was diagnosed after 10 years of suffering.

Judy Wilsher's condition would tire her out

The grandmother from Kent had surgery for achalasia in 2008 and this had left Judy unable to digest meals properly as the condition affects how food reached the gullet.

The problem was that the surgery which was designed to cure the issue actually left her bringing up "bright yellow bile" after every meal and a constant feeling of nauseous.

Judy lost over a stone and a half in weight and underwent a further four surgeries to correct the oesophagus disorder.

Explaining how she felt at the time, Judy said: "It was like I had a golfball stuck down my throat and I was choking."

It was a decade of hell

The mystery illness was debilitating and she said that she had to live with it everyday.

Judy continued: "I miss spending time with my grandchildren. I don’t have the energy to be charging around after them now. I’m losing weight and that’s what’s worrying me.

"It's very frustrating when nobody can help with you, nobody knows. It's dreadful. I just want someone to help me find out what it is."

The BBC show sent her to see Dr Shidrawi at The Wellington Hospital in North London and Judy went worrying that she would be diagnosed with cancer.

The Consultant Gastroenterologist believed that there had been damage to the vagus nerve during her surgery in 2008.

This nerve runs from the brain to the abdomen and he tested the acidic levels in her stomach as this would show whether the messages from her vagus nerve were reaching her pancreas.

There were tears on screen when the doctor shared the news with Judy that he reckoned he had found the reason for her sickness.

Speaking to her daughter on the phone, a tearful Judy said: "The doctor says it's something called the vagus nerve that isn't working properly and he thinks there is a way he can get me better.

"He's not promised 100 per cent, but I'll be having tests."

Two of the three tests the doctor did on Judy showed that it was taking over an hour longer than it should to empty her stomach and this was why she was being sick so frequently.

Dr Shidrawi said: "After all these years we can tell you what the problem is and why you are suffering the way you are, there is no doubt in my mind there has been some damage to the vagus vein.

"The next step is to bring you in here and hopefully we can make a difference."

He continued to say that he wanted to operate on Judy's stomach to add a valve to help empty it as it was impossible to mend the vagus nerve.

Dr Shidrawi continued: "It was a very important moment. To see her reaction, her eyes welled up, her husband's eyes welled up, we're privileged to share that moment with them, because in that split second she knew there was a reason she was feeling like that.

"She wasn't going out of her mind, it never ceases to amaze me how emotional that moment is and how grateful patients are and the satisfaction I get from telling them something nobody else has."
