Phagophilia is a rare word used to describe an intense desire to eat unusual foods. However, there are several synonyms for this term, including pica, which is characterized by an appetite for non-food substances such as dirt or chalk. Then there is coprophagia, which is the consumption of feces. There is also geophagy, which refers to the habit of eating soil. Some people with phagophilia may also experience a desire to eat non-human items such as paper, hair, or metal. Regardless of what it's called, phagophilia is considered a serious psychological disorder that requires treatment. Therapy and medications can help people overcome this condition.
