Hello dear
I understand your concern.
Eating slate pencil called the PICA.
It is due to deficiency of the iron, zinc, calcium and psychological problem.
Continuous behaviour cause intestinal worm infestations and aggravation of psychological behaviour.
I would suggests to undergo
complete blood count, Hb, Stool analysis, Serum calcium and zinc levels.
According to the tests report iron and
calcium supplements will helpful.
Take
revital multivitamin tablet for 2-3 months.
Symptoms will disappear after the treatment.
If they persist,then it could be a psychological behaviour.
Behavioural modification therapies are helpful to correct this.
Hope this may help you
Contact HCM for further health query
Best regards
Dr. Sagar
