Hi I am dr Kadhir,
At first I wold explain you the causes behind blood in stools.. most common cause in a well thriving child is
food allergy, that could be cows milk, wheat(gluten),nuts depends on the allergen.. or a bacterial infection (
dysentery ).. but in dysentery kids usually have fever,
abdominal pain and vomiting ..
If child is having
constipation causes like rectal ulcer, fissure should be ruled out.
There are few serious conditions but they are so rare .. they are uncommon in a well thriving child.
Inflammatory bowel disease (IBD)is one such condition but I have seen only 1 infant with IBD in past 9yrs of pediatric practice .
I can reassure that this could be normal if baby is otherwise doing well. Find out the food and avoid it, its the best way to diagnose allergy .wait and watch for recurrence of symptoms .
Iron deficiency anemia is common in this age group, as mother's milk is not a good source of iron and body's normal iron stores deplete by the age of 6 months, it is good that u start
iron supplements and iron rich food.
It is difficult to comment the relationship between iron deficiency and blood in stools. But occult blood loss is definitely a cause of anemia in conditions like meckels diverticulum in a well thriving child.
My best advice is avoid allergen, wait and watch , treat anemia.. follow up if symptoms reccur or if anemia not improving..
Thank you for using healthcare magic
