Hello Doctor! My 3 year and a half year old son seems to have developed a vomiting tendency since the past three days. Although he doesn t vomit, his stomach becomes a bit upset after eating ,usually after lunch.He sometimes suffers from constipation too.A year and a half ago when he was constipated his paediatrician advised lactitol monohydrate 66.67%(Gutclear) for a month after which he was fine .Five months back he again had constipation and the doctor advised 15ml of Gutclear daily .Since his bowel movement became regular after a few days i stopped the medicine four months back.When asked he would say that he feels uneasy(maybe a bit bloated) and would have hiccups(usually after lunch).Otherwise he is a highly active and a happy child.Please help!
