The stomach bug, also known as the stomach flu, affects up to 21 million people yearly. In the U.S., stomach flu is the second-most common illness. Although typically self-resolving, symptoms can be challenging to deal with at home. It is essential to know at what point you should visit your doctor.  

As a general rule of thumb, if your symptoms consist of frequent vomiting, inability to keep down fluids, severe diarrhea, or high fever, make sure to seek immediate medical attention. 

When should I seek medical assistance? 

It might be a sign that you need medical attention if you find your symptoms are becoming more severe or if your symptoms are lasting longer than expected. Call your primary care provider if you have experienced any of the following symptoms.  

  • Vomiting blood
  • Bloody diarrhea or blood in your bowel movements
  • Fever above 104 F
  • Severe abdominal pain or cramping
  • Unable to keep liquids down for over 24 hours
  • Severe dehydration - characterized by little to no urine production, dry mouth, or excessive thirst
  • Dizziness or loss of consciousness
