Hi
Welcome to the healthcaremagic
In 99% of children
chronic constipation is because of improper diet.Give him high fibre diet and liquids.
NO maids based food such as bread,buns,biscuits, cake,noodles
NO chocolate
Less milk
NO apple,pomogranate and banana
Give lots of water, one bowl soup daily,one fruit daily,green salad, one anjeer and five overnight water soaked black raisins daily.
Give macrogol like ezlax continuously for three months
In children not showing improvement to these regimen we investigate for remaining 1% causes like
hypothyroidism, HIRSHPRUNG disease, celiac disease
