<human>: My son has been vomiting for no apparent reason - he is 4 years old - dr did an x-ray and said he was constipated- now he is taking muralax... if he doesn t take it for a day, he starts vomiting - now he is also saying the top of his head hurts. We have a CT scheduled. Is there anything gastrointestinally that could be causing this?
<bot>: first, in order to constipation to cause vomiting it needs to be so sever that child can't pass stool for days or even more than a week .and sometimes sever straining in the bathroom can cause headache, but constipation is something you notice clearly, and the child suffer from it and doesn't need an X-ray to tell you that. In other words : if your child has sever constipation, it can explain all these symptoms .BUT, if he doesn't, we should worry about increasing intracranial pressure; the pressure inside his head, which gives him headaches and vomiting, a brain CT and ophthalmic exam is very helpful to exclude this I hope this helps
