Thank you for your query on Healthcare Magic.
Most of the children will complain of pain abdomen after food.
But usually there will be no underlying any organic problem in spite of extensive investigations.
The stool test
is normal and not suggestive of any abnormality if child is not having any other complaints except for stomach pain.
Just observe for the severity or any associated complaints like loose stools or vomitings.
If it is associated with other problems like vomiting, loose stool or severe enough to wake him in the nigh, then the pain can be further evaluated with ultrasound
Give him soft diet
Avoid fried, oily, and junk food.
Hope I have answered your query.
