I have a hiatus hernia and taking esomeprazole for reflux which has been working . yesterday i vomited all day with diarreah. today its stopped but i?

Question unclear but: Having an occasional episode of diarrhea plus vomiting can be due to something in the food (such as food poisoning by bacteria or their secreted chemicals). Other possible causes of such symptoms include stomach viruses, medications, etc... If symptoms are more than brief and mild, one's primary care doctor can review one's history and do an exam to see if there is anything to worry about.
