Iron deficiency in Children

Updated: Jul 26, 2022

If your child is suffering from one of the iron deficiency symptoms, it is better to check for iron level:

Delayed growth or development

Impaired cognitive function;

Decreased memory,

Impaired learning and concentration

Behavioural disturbances


PICA – eating of non-nutritive substances such as paper, wood and soil 1

At school, it can cause lower school performances and at home, it can cause lots of difficulties in parenting. If neglected it can have detrimental effects on the well-being of our children.

If it gets severe it can cause iron deficiency anaemia ( decreased red cells in the blood).

What are the risk factors of iron deficiency?


Iron deficiency during pregnancy

Prematurity and/or low birth-weight

Multiple pregnancies of mother

Exclusive breastfeeding after 6 months 

Late or insufficient introduction of iron-rich solids

Excess cow's milk consumption

Aboriginal and Torres Strait Islander 


Vegetarian or vegan diet

Gastrointestinal disorders e.g. Meckel’s diverticulum, coeliac disease, inflammatory bowel disease, gastric or intestinal surgery or infection Other chronic blood loss


Vegetarian or vegan diet

Heavy menstrual bleeding

Gastrointestinal disorders e.g. coeliac disease, inflammatory bowel disease, gastric or intestinal surgery or infection

Other chronic blood loss 

Extreme athletes

Iron deficiency investigations:

Your doctor can order ferritin levels to check on iron reserve and FBE to check on red cells.

In iron deficiency anaemia rec cells get smaller and get less haemoglobin.

Iron deficiency treatment:

Preventive dose for iron deficiency is 1-2 mg/kg/day

Treatment of iron deficiency needs 3-6 mg/kg/day 2

In severe anaemia, higher doses can be prescribed. The iron supplement should be continued for 3 months after correction of anaemia to make sure good iron reserve is maintained.

Iron supplements can cause constipation or black stool. If constipation happens please visit your doctor to discuss it.

In older children, a high fibre diet can help but for younger ones times it is necessary to use proper laxatives. 3

Best sources of iron:

" Animal foods (haem iron) include:

 Lean red meats such as beef, lamb and veal.

It was extremely well-expressed by you. Kids with iron deficiencies are a common problem. Therefore, from a young age, we should take care of them and offer them food that is healthy. In case you need assistance with your homework at any time, get in touch with help me do my homework Service. I've always counted on them to help me with my studies because they offer support for college and university students in London.
