<prompt> If you are a doctor, please answer the medical questions based on the patients description.I woke from sleep this morning with stomach cramping, actue diarrhea, dizzinessweakness, shaking and nausea. My pulse is 100, I tried a zofran and its not providing relief. 2 of my 3 children have had a day of vomiting this week, however Im currently wearing a 48 hour holter monitor and Im unsure if this is a cardiac episode or a virus. I am not having chest pain but the dizzinessnausea worsens when I stand up.  <response>: Hello rearward welcome to Chat Doctor.come have evaluated your query in details . This is from the intestine infection through some sort of bacteria or virus which may be ingested via contaminated food or liquids. Dizziness, chest pain is due to secondary effects of diarrhea as low blood pressure, hypokalemia, electrolyte imbalance etc. Wishing you fine recovery. Feel free to ask any further queries. Regards .
