From CNN:

CNN) It may not be the most appetizing reading before a hearty holiday meal, but the New England Journal of Medicine is devoting part of its Thanksgiving issue to a giant hairball—and not the feline kind.

Doctors say this hairball removed from a woman’s stomach weighed 10 pounds.

“On questioning, the patient stated that she had had a habit of eating her hair for many years—a condition called trichophagia,” they wrote.

The prestigious journal details the case of a previously healthy 18-year-old woman who consulted a team of gastrointestinal specialists.

She complained of a five-month history of pain and swelling in her abdomen, vomiting after eating and a 40-pound weight loss.
