[|Human|] my 10 month old son has been projectile vomiting most nights for 4 weeks we have had him at the hospital but they said it was just a tummy bug, he is well in every other way but at night he wont sleep more than 2 hours befor being sick again, what can be causing this?
[|AI|]  Welcome to the Chat Doctor The most likely reason for vomiting spells only at night may be gastroesophageal reflux disease (HERD) or gastritis. To confirm the diagnosis pH studies are available in hospitals. Measures such as keeping child upright for a while after feeds, pro kinetic agents like Spy. Perform and head end elevation at sleep are useful measure to avoid HERD. You may also give him antacids such as Spy. Di gene for relief from gastritis. Hopefully this will be useful. Take care
