Symptoms & next steps Digestive symptoms and signs of dehydration Track fluid intake, symptoms, and warning signs while arranging appropriate care. Reviewed by Nicholas Atudonyang, MD — October 2026. Record more than the main symptom For nausea, vomiting, or diarrhea, note when symptoms began, how often they occur, whether you can drink, and whether you have abdominal pain, fever, or blood in the stool. Mention travel, sick contacts, and any relevant health conditions. Watch for dehydration Marked thirst, a dry mouth, darker urine, less urination, light-headedness, or fainting can be warning signs. Being unable to keep up with fluid losses requires clinical advice. People who are older, pregnant, immunocompromised, or living with other conditions may need earlier assessment. Seek care for concerning progression Frequent vomiting, severe abdominal pain, black or bloody stools, high fever, or symptoms that persist or worsen deserve prompt medical assessment. Confusion, fainting, or severe illness may require emergency care. Plan a useful conversation Bring a short symptom timeline and explain what you have been able to drink or eat. Ask whether an examination or testing is needed. This information cannot confirm a stomach virus or rule out another abdominal problem, and it does not replace an individualized assessment. Emergency symptoms? Call 911 or go to the nearest emergency department. Do not wait for a routine appointment, phone call back or email reply.
