A schoolgirl was shocked to discover she had a huge hairball in her stomach after complaining about feeling sick.
Melissa Williams, 13, ate her own hair whenever she felt anxious and ended up with a rugby ball-sized mass in her stomach.
The tangled hair had to be cut into four sections by doctors before they could remove each one, the Liverpool Echo reported.
In a bid to raise awareness, the teenager's family is speaking out about her condition, known as Rapunzel Syndrome.
The hairball, which measured between eight and 10cm in diameter, was removed in October last year.
Mum Jackie Williams, 40, and dad, Gary Jones, 47, didn’t know anything was wrong until Melissa, from Liverpool, started complaining of severe stomach pains.
Jackie explained she took her daughter to and from the GP over the course of a year but "carried on persisting" when they told her that Melissa's problems were due to anxiety.
She told The ECHO: "She was getting really badly bullied at school for three years and when she would get anxious she would pull out her own hair and eat it.
"The first things we noticed were that she was feeling and being sick, had poor appetite and lost about one stone in weight. I thought she had an eating disorder because she wasn't eating.
"She started getting sent home from school a lot and asking not to go in because she felt sick, but because it was on the same day every week I thought it was a lesson she didn't like.
"We were to and from the doctors about half a dozen times over the year but we carried on persisting."
The pain got significantly worse over a two week period and Jackie decided to take Melissa to Alder Hey Children's Hospital.
Once at the hospital, doctors could feel Melissa's stomach was tender. They then found a huge mass, but didn't know what it was.
Jackie said: "They said they had never seen this before, they did an X-ray and they saw a big mass in her stomach but didn't know what it was.
"It was actually my neighbour that said she read something years ago about people eating their hair, and that's what it was."
Melissa went into emergency surgery at Alder Hey where doctors had to cut the hairball into four sections before removing each of them with two hands, due to their weight.
Jackie continued: "The doctors said if we didn't take Mel in when we did she might not have pulled through the surgery.
"She was relieved once the pain was gone and she was so brave."
After the surgery, Melissa was in hospital for two weeks due to issues with her bloods and excess fluid in her stomach.
Melissa was then well enough to return home for four weeks before ending up in hospital again with three different infections.
Melissa does still pull out her hair sometimes but no longer eats it. She is being supported by Child and Adolescent Mental Health Services (CAMHS).
Now her family want to raise awareness of Rapunzel Syndrome and make sure other parents know the signs and symptoms to look out for.
Jackie said: "Parents should look out for any changes in their kids' hair, and it's not just the hair on their head. It can be eyelashes and eyebrows.
"Also any changes to eating, sickness and stomach pains are all symptoms.
"I'd also say that parents shouldn't give up when going to the GP, If you know something is wrong with your child then keep going back, don't give up and don't take no for an answer."
