18 Month Old With Ongoing Vomiting/Diarrhea for 3 Weeks

[larsead]

My 18 month old daughter has had diarrhea and been vomiting for the past 3 weeks.  She vomited the first day once and seemed to feel fine afterward.  The following two days she had diarrhea.  She felt fine the following day. She then began vomiting again after that the second week.  During the second week she vomited about three days out of the week and had diarrhea the entire time.  The third week (this week) she finally was admited into the hospital for dehydration because she kept vomiting Tuesday evening.  She went Wednesday no bowel movement but vomited Wednesday nigh.  Thursday the diarrhea began again and she vomited three times.  Friday she vomited once with diarrhea throughout the whole day.  Saturday and Sunday she did not vomit but still had diarrhea.  Monday she vomited once and had diarrhea throughout the whole day.  She has had constipation issues since she was a newborn.  She has been on Miralax since she was three months old.  I took her off Miralax about two months ago because I thought she was fine.  When her physician performed an abdominal xray, he noticed that she had impacted stools inside her intestines (I apologize I do not the medical termonolgy).  He believes that could be a cause of her symptoms, but I am not sure.  As of last Tuesday she has lost over a pound (she weighed in at 19 lbs 2 oz).  She constantly wants to eat and drink.  I have not given her milk.   I do not know if this has anything to do with what she has, but a week ago last Sunday I had flu like symptoms (vomiting and diarrhea) that only lasted about 24 hours.  I also got the same thing this last Friday (vomiting and diarrhea).  I feel fine now.  I only add that in there because it could possibly be related???  My husband has not been sick at all.

Has anything been done to rid her of the impacted stool?  When a child get impacted like this, a ball of stool forms and everything that can, goes around it, resulting in leakage or diarrhea.  But I don't know where the vomiting would come from.  Vomiting accompanied with diarrhea is serious in a young child like this.  I would get her in to see a pediatric gastroenterologist ASAP!
