My cousin was a premature baby, and ever since he was small, he has had vomiting that he has to go to the ER for. He is now my age (18) and is in the Marines, but he recently came home for a visit and after a few minutes, began vomiting uncontrollably. My aunt had to take him to the hospital, and they gave him enough medication to make him stop vomiting, but he didn't. Eventually they got it under control, and they are going to run tests to see what's wrong, but he has had this happen to him since he was small child with almost perfect intervals of four months in between each vomiting attack.
I've read articles about cyclic vomiting syndrome, but what makes me think that this is NOT this disorder is that, whenever he has a vomiting attack, his white blood cell count skyrockets, as if his body is attempting to fight an infection.
He does not usually have any diarrhea or stomach pain beforehand or afterwards, although he does experience stomach pain WHILE he is vomiting. Also, he intermittently runs a fever during these attacks. During this most recent attack, he was running a fever.
My aunt has tried to figure out what is wrong with him since this first starting when he was little, and now that he is in the Marines and needs to know what is compromising his health like this, I wanted to help and try to find a diagnosis for him.
If anyone has any ideas, please, it would do my family a great deal of help. He will be going back to his base in Japan in a few weeks.
