An 18-year-old girl suffering from a psychological condition ate her own hair and formed a massive hairball in her stomach, US media reported Monday.

The teen went to her doctor after complaining of stomach pains and vomiting. She had also lost over dozens of pounds over a five-month period, according to the report.

Doctors at Rush Medical Center in Chicago carried out a scan and were amazed to find the huge mass of hair blocking her entire stomach and removed the massive hairball from the stomach by surgery.

The hairball measured 15 inches (38cm) by 7 inches(18cm) by 7 inches (18cm) when it was removed.
