<s>[INST] My father has been diagnsed with emphysema and copd but my question is. Can he vomit. A lot because of it or is it some other reason he was diagnosed with stomach cancer four years ago but he was on gleevec for three years so is it cancer coming back or war [/INST] Thanks for your question on Chat Doctor. . In my opinion you should consult gastroenterologist and get done UPPER GIS COPY.  As possibility of recurrence of stomach cancer is more. This may cause narrowing of lumen and obstruction to the food. So due to mechanical obstruction vomiting occurs. This can be the possibility.  So to rule out this upper GI copy is must. Also get done CT abdomen to rule out metastases in lymph nodes and distal bowel. </s>
