Frequent early morning vomiting
in a well female child of age 4-5 year without any obvious abnormality is suggestive of cyclic vomiting syndrome. If mother had same history in past then its more suggestive. But before making a diagnosis of cyclic vomiting syndrome other causes should be ruled out by thorough investigations like complete blood count
, renal function test, liver
function test, upper g.i. endoscopy
, USG abdomen, metabolic scrrening and urine examination.
If it is CVS then it usually resolves itself by conservative management over a period of time.
So I would suggest you to consult your physician for diagnosis of the condition and management accordingly.
