People eat chalk, due to Pica, an eating disorder characterised by the ingestion of non-nutritive items, which is associated with chalk consumption.
It can be caused due to lack of iron or zinc, along with psychological reasons such as stress, anxiety, or emotional distress.
Some individuals find the texture and taste of chalk to be comfortable or soothing.
It can cause gastrointestinal issues, irritate stomach, intestine linings, conceal vitamin deficiencies, in rare cases, lead to serious health issues.
Consult the doctor if you are concerned about Pica's behaviour and they’d assist in determining the cause and recommend suitable treatment.
