My five year old son has been vomiting about once a week for over a month. He throws up until his stomach is empty and then he is fine again. The doctor thought maybe he had a dairy allergy so we took him off of all dairy, but he got sick and threw up again last night. It was only a small amount, not until his stomach was empty, but he has felt sick on and off all day today with no more vomiting.
Hi...once week vomiting need not be worried about if the kid is otherwise active and in-between episodes normal. This is definitely not diary allergy keeping in mind the age and frequency of symptoms. You need to worry about vomiting only if following symptoms are there, - 1. Green or bilious vomiting.2. Severe headache.3. Double vision.4. Weakness or restriction of movement of any body part.5. Seizures.6. Altered behavior.7. High blood pressure. If these are there, it requires further evaluation. Otherwise, be rest assured. Regards -
