In a very unique case, doctors in the Russian city of Tomsk pulled a mass of 500 grams of hair from the stomach of a 16-year-old girl.
The doctors confirmed that the girl continued to chew her hair for 10 years, until she stuck in her stomach and occupied about 80% of her size.
The girl first contacted the specialists who complained about her hair loss. However, the test proved to be suffering from anemia and strange body in the abdomen.
"Stacking of hair of this size can cause gastrointestinal obstruction," said the head doctor of the hospital, Andrei Karavaev. So the doctors decided to immediately perform surgery, the surgeons cut the abdominal wall and opened the tummy cavity.
The girl is recovering now and she is well, but she may need the help of a psychiatrist to get rid of the habits of rubbing hair.
