n]]. Cattle are also known to accumulate hairballs, but as they do not vomit, these are found usually after death and can be quite large.
Although uncommon in humans, some hairballs have been reported. These hairballs occur when hair strands collect in the stomach and are unable to be ejected as a result of the friction on the surface of the gastric mucosa. Hairballs are often seen in young girls as a result of trichophagia, trichotillomania and pica.Cite error: A <ref> tag is missing the closing </ref> (see the help page). since hair cannot be digested or passed by the human gastrointestinal system, and (assuming it is identified) even vomiting may be ineffective at removing the hair mass. This can result in the general impairment of the digestive system.
