Viral Gastroenteritis (Stomach Flu)
Viral gastroenteritis commonly referred to as stomach flu is a highly contagious infection of the intestines caused by several viruses. Despite its nickname, it is not related to the flu (influenza). Stomach flu leads to inflammation of the stomach and intestines, causing a range of uncomfortable gastrointestinal symptoms.
If you or your loved ones are experiencing recurring digestive issues, understanding the early signs of viral gastroenteritis can help you seek timely treatment from a stomach specialist in Gurgaon like Dr. Sukrit Singh Sethi.
What is Viral Gastroenteritis?
Viral gastroenteritis is an intestinal infection marked by watery diarrhea, abdominal cramps, nausea or vomiting, and sometimes fever. It can affect people of all ages and spreads rapidly, especially in places with poor sanitation or close personal contact.
The most common viruses responsible for stomach flu include:
- Norovirus – often spreads through contaminated food or water.
- Rotavirus – a common cause in infants and young children.
- Adenovirus and Astrovirus – less common, but still possible culprits.
Common Symptoms of Stomach Flu
Symptoms usually begin 1–3 days after exposure to the virus and can last from a day to over a week. The severity varies depending on the viral strain and the individual's immunity.
Key symptoms of viral gastroenteritis include:
- Watery, non-bloody diarrhea
- Nausea and vomiting
- Abdominal cramps or pain
- Low-grade fever
- Headache and muscle aches
- Fatigue or general weakness
It is essential to stay hydrated, as dehydration is the most serious complication, especially in children and older adults.
What Causes Viral Gastroenteritis?
The stomach flu is caused by viruses that are easily spread through:
- Contaminated food or drinking water
- Direct contact with an infected person
- Touching surfaces or objects contaminated with the virus
Poor hand hygiene, especially in communal settings like schools, daycare centers, or hospitals, contributes to the rapid spread of this illness.
Diagnosis: How Is Stomach Flu Identified?
Most cases of viral gastroenteritis are diagnosed based on symptoms and physical examination. However, in severe or prolonged cases, your stomach specialist in Gurgaon may recommend:
- Stool tests to identify viral presence
- Rapid antigen tests for rotavirus or norovirus
- Blood tests to monitor signs of dehydration or infection
Early and accurate diagnosis helps differentiate stomach flu from bacterial infections or parasitic conditions, which may require different treatments.
Treatment Options for Viral Gastroenteritis
There is no specific medication to treat the viruses causing stomach flu. The main goal of treatment is to prevent dehydration and manage symptoms.
1. Rehydration
- Oral Rehydration Solutions (ORS): Maintain fluid and electrolyte balance.
- Intravenous (IV) fluids: In severe cases, especially if vomiting prevents oral intake.
2. Dietary Adjustmentsn
- Follow the BRAT diet (Bananas, Rice, Applesauce, Toast) to ease digestion.
- Avoid dairy, spicy, fatty, or fibrous foods temporarily.
- Stay away from caffeine and alcohol.
3. Symptom Management
- Antiemetics for nausea/vomiting (prescribed by a doctor)
- Probiotics may help restore gut flora
- Over-the-counter anti-diarrheal medications are generally not advised without consulting a doctor.
When to See a Doctor?
Most mild cases of stomach flu resolve on their own, but you should consult a stomach specialist if you or a loved one experience:
- Symptoms lasting more than 2–3 days
- Blood in stool or vomit
- Signs of severe dehydration (dry mouth, sunken eyes, reduced urination)
- High fever (above 102°F)
- Continuous vomiting preventing fluid intake

- Use alcohol-based hand sanitizers when soap is unavailable
- Disinfect commonly touched surfaces (doorknobs, kitchen counters, etc.)
- Avoid sharing utensils, towels, or food with an infected person
- Drink clean, purified water and avoid raw or undercooked food
Vaccination against rotavirus is also available and recommended for infants as part of routine immunization.
