My son was born with Hirschprungs he had a pull through surgery at 5 weeks old, he is now 5 years old, he is continent but has a porrige like poo and poops for 20-30 minutes about 2 times a day, he has food issues refuses most foods, and low in iron. last week he got severe stomach pain , exessive sweating, fatigue close to loss of counciousness, rushed him to emergency, they got him on a drip he was like arug doll, fainting. To me he was in shock, the thow up and later blood in the poo. His temperature dropped to 35.5, was released from hospital 2 days later, x ray and ultrasound did not show any abnormalities, blood test are still pending they had difficuties taking his blood, my question is, could this be enterocolitis? And this has been 8 days ago, should have been a blood test done for this specific diagnosis Enterocolitis?
