I Am A Health Care Worker Who Works The Night

I am a health care worker who works the night shift (7am-7pm) and I have been getting weird spouts of nausea/vomiting. It doesn't happen every time I work the night shift, but it has definitely happened a handful of times. I'm starting to feel concerned. I am a healthy person, eat a normal diet, drink lots of water. Would you suggest going to see a doctor and perhaps get blood work done to find the root problem?
