Causes of chronic constipation in children are similar to the adults having constipation.

Children may tend to

eat more processed food - snacks containing more fat and less fiber

skip/avoid visiting toilet when they should

not chew food properly because they are in a hurry to go to play or somewhere else,

forget to drink water and other healthy fluids

Children postpone/avoid going to toilet when they feel the urge. That may be because they do not want to interrupt what they are doing or

they may be afraid to go to the toilet alone.

They may be eating more junk food that is low fiber.

They forget to drink water or other fluids.

If they have painful bowel movement earlier, they want to avoid going to toilet. They do not realize that doing so will make the problem worse.

They may not like to use the toilet in the school for some reason.

Some digestive disorders can cause chronic constipation in children. Under active thyroid, allergy to dairy products, cows milk can be the cause.

Some medicines also may cause constipation as a side effect.
