Hello - thanks for asking your question.
This absolutely should be evaluated and it is good that you are taking to steps to make this happen.
There are many causes for vomiting. These include
pancreatitisAcute pancreatitis
Chronic pancreatitis
Pancreatitis
Pancreatitis, acute - ct scan
Pancreatitis, chronic - ct scan, biliary disease, an ulcer or inflammation of the esophagus or stomach, any type of cancer including esophageal or stomach cancer, delayed gastric emptying (gastroparesis), or metabolic distubances such as diabetes, hypercalcemia or adrenal insufficiency.
Given his age, there is increased risk for an obstructive lesion (i.e. cancer). Ideally, an upper endoscopy should be performed. An upper GI series as you suggest would also be an acceptable initial study.
If that is negative, you may want to consider a gastric emptying scan to evaluate for gastroparesis.
In any case, this needs to be absolutely evaluated and it seems that you are taking the right steps to make this happen.
Followup with your personal physician is essential.
