I am writing on behalf of my son. He is almost 17 and has had issues with morning nausea and vomiting for several years. It comes and goes and lasts 3-5 days. It will wake him up in the morning for several days and he will either vomit (most often only once) or feel nauseous for an hour or so and then is perfectly fine the rest of the day. When it ends he is fine for several weeks or months before it starts again. He is otherwise very healthy and active although quite thin, even on the edge of being underweight. He normally has a good appetite except during these episodes when he seems to get full very quickly.
I am hoping for some insight on what could be causing this or how to help with it. I strongly believe it is NOT linked to stress (I have been doing a lot of online research and this has come up often) as he is a very confident person and not at all a worrier.
Does he have allergies or sinus issues? If so, it could be from post nasal drip (PND). It can cause this as well as other issues. I quit drinking milk altogether when just the small amount in my cereal would curdle due to the PND in my stomach...not pleasant vomiting that.
the only allergies he has are seasonal ones in the spring and I havent noticed any sinus issues other than when he has a cold. His runny nose (and cough) last for many days after he is feeling better from the other cold symptoms.
