 Hi, my name is Dr. Radhakrishnan. I'm a pediatric surgeon and a pediatric urologist and I work at the Manipal Hospital in Bangalore. Organic causes would mean that the child has a physical problem leading to the constipation. Now I must say that these are quite rare. To enumerate a few of them, one of the conditions that we do see once in a way is something called Hirschsprung's disease where the nerves in the lower end of the bowel do not work properly. The other fairly common cause, organic cause for childhood constipation is where the nerves do not develop properly from the spinal cord itself leading to problems within the bowel and the bladder causing problems in the child where the child has a problem passing stool and passing urine. As I said, the rare organic causes of constipation require customized treatment. Hirschsprung's disease requires surgery. The other causes of organic causes of constipation such as the mal-development of nerves are again a complicated problem. Each child is to be individualized and treatment depends on the condition of that particular child.
