Doctors eventually told Jodie Collins that something very specific was causing her teenage daughter’s ongoing stomach pain.
Erin, 14, had been complaining about painful stomach aches since November last year. At first, her mom thought it might be related to certain foods or even menstrual cramps, so she didn’t imagine it could be something more unusual.
Concerned by how bad the pain was getting, Jodie went to their local hospital determined to get answers, urging doctors to investigate further.
That’s when she was told something alarming — there was a large, hard mass in Erin’s stomach, and it wasn’t food. It was made entirely of hair.
Before long, Erin was transferred to Bristol Children’s Hospital, where specialists determined she would need surgery to remove the enormous hairball. The mass measured 8.3 inches across — far bigger than anyone expected.

Jodie explained that Erin had always loved twirling her hair since she was small, but she had never noticed her actually putting hair in her mouth.
Doctors suggested Erin might have been chewing or swallowing hair in her sleep without realizing it.
“Erin was suffering with really bad stomach cramps for a good six months. I put it down to food intolerances, I thought she could be lactose or gluten intolerant.” Jodie explained.
“The pain was quite high up. It was really sporadic but when it came, it was really bad and she had to be off school.” she continued, adding that earlier scans like ultrasounds hadn’t revealed the problem.
“But I have never seen her put her hair in her mouth, which is why it was shocking to me.”
One surgeon suggested Erin might have been doing it without realizing, and the hairball had stretched her stomach to three times its normal size.

Doctors believe the mass could have been forming for several years. Fortunately, it hadn’t made its way into her intestines, which could have been much more dangerous.
As Jodie put it: “It took up pretty much the whole of her stomach.”
After spending five days on a nil-by-mouth routine and having her stomach drained, doctors warned that if the hairball had remained untreated, Erin could have collapsed from the complications.
“We’ve now bought her one of those bonnets to sleep in just in case she’s doing it in her sleep.” her mom added, urging other parents to consider giving children fidget toys or even cognitive behavioral therapy in more serious cases to prevent such habits from turning dangerous.
