Hello, my younger brother (2 and a half) has been constantly vomiting from about 8 or 9 moths of age. He has no illness, no symptoms of cold or flu and appears perfectly healthy. He usually vomits when he laughs too hard, runs around too much, crying too hard, drinking water, milk or juice. Even small amounts of phlegm at the back of his throat can send him into pools of vomit. On average he will vomit about 2 or 3 times a day. My mother took him to our PG and they said it was to do with a weak esophagus. I don t believe he received any medication for it However this was a diagnosis from when he was about a year old. It has been quite a while. He still appears to be the same when will he grow out of it? Is there a way to help?
