Nausea and Vomiting

Your symptoms (nausea or vomiting, fever, and brief episodes of abdominal pain) are very consistent with a viral infection that is primarily affecting your stomach and intestinal tract, known as "gastroenteritis." This condition is sometimes referred to as "the stomach flu." Many different viruses can cause gastroenteritis. Most of them also cause diarrhea, but that symptom can lag behind the symptoms you are experiencing.

You do not necessarily require evaluation for your symptoms since they have been occurring for fewer than five days. If your symptoms persist longer than a week or if they are not clearly improving on their own by the time you are in your third day of symptoms, then you need to see your doctor. Vomiting or diarrhea can deplete you of fluids and electrolytes, so repeated vomiting or diarrhea requires medical treatment if it results in a lasting lightheaded feeling or weakness.
