A disease that makes you want to eat mud or hair! Pica is quite a mysterious affliction and has left doctors baffled for a long while. It’s a psychological disorder that creates a growing appetite for things that are not nutritious, or considered food.
People suffering from Pica may develop a habit of eating things like dirt, ice, hair, paper, stone, metal or even glass! While there is no definite cause for Pica, some aggravating factors could be stress, cultural factors, and deficiencies of zinc, iron or other nutrients.
