Doctors at Kalwa's civic run Chhatrapati Shivaji Maharaj Hospital performed a two-hour long surgery on Wednesday on a 15-year-old girl and removed a hair ball weighing 2.5 kg from her stomach, a doctor said.
"She is a mentally retarded girl with a long standing habit of eating of her own hair and rough paper. She was brought for loss of appetite, loss of weight and abdominal distension," said Sukesh Thakur, a member of the three-member team of doctors including Vishwas Sapatnekar and Anupama Takawale, who performed the surgery.
"During investigation, she was diagnosed with a rare disease called trichobazor, where a hair ball is collected in the stomach leading to distension of stomach, loss of appetite and loss of weight," he said.
The mass of hair removed was a foot long and half a foot wide, the doctor said.
