My son has had trouble since birth with acid reflux. He takes it by spells. He has been hospitalized twice so far with it. He started throwing up last Wed. night. So far all the tests have showed is constipation. He has been on Miralax and Milk of Mag since then but as of date no major bowel movements. He goes twice a day but just his regular amounts. He vomitted 5 times yesterday. I know there are several people on here that have dealt with constipation but has that ever caused your kids to vomit? Any suggestions while we are waiting on the specialist?
