About Stomach Flu (Gastroenteritis)
Stomach flu, medically known as gastroenteritis, is an inflammation of the stomach and intestines. It’s often caused by viruses (viral gastroenteritis), but can also be due to bacteria or parasites (bacterial gastroenteritis). This common illness leads to unpleasant symptoms like diarrhea, vomiting, abdominal cramps, and sometimes fever. While usually not serious for healthy adults, it can cause significant dehydration, especially in children and the elderly, and can severely disrupt your travel plans. Gastroenteritis is particularly common when traveling due to exposure to new pathogens in food or water, or close contact with infected individuals. DocOnTrip offers convenient online consultations to help assess your symptoms, identify the likely cause, and provide essential advice for managing your stomach flu, ensuring a faster recovery and return to enjoying your trip.
Symptoms
- Diarrhea (often watery, non-bloody).
- Nausea and vomiting (can be sudden and forceful).
- Abdominal cramps or pain.
- Low-grade fever.
- Headache.
- Muscle aches or body aches.
- Loss of appetite.
- Dehydration symptoms (thirst, dry mouth, decreased urination, fatigue, dizziness).
Causes & Risk Factors
Gastroenteritis can be caused by various pathogens:
- Viruses (most common):
- Norovirus: Highly contagious, often spread through contaminated food/water or direct contact. Common on cruise ships and in crowded settings.
- Rotavirus: Primarily affects infants and young children, though adults can get it.
- Adenovirus: Can affect people of all ages.
- Bacteria (less common, but can cause more severe illness):
- Salmonella: From raw or undercooked poultry, eggs, unpasteurized milk.
- E. coli: From contaminated meat, produce, or water.
- Campylobacter: From undercooked poultry, unpasteurized milk, contaminated water.
- Shigella: From contaminated food/water or person-to-person contact.
- Parasites (less common, but can cause prolonged symptoms):
- Giardia: From contaminated water.
- Cryptosporidium: From contaminated water.
Travel-Specific Risk Factors:
- Consuming unwashed or improperly prepared food.
- Drinking untreated water or ice.
- Poor hand hygiene (especially after using the restroom or before eating).
- Close contact with infected individuals in crowded environments.
Diagnosis via Teleconsultation
Our doctors can assess stomach flu by discussing your symptoms in detail: onset, frequency, severity of diarrhea and vomiting, presence of fever, and any associated pain. They will inquire about recent food and water consumption, travel history, and any potential exposure to sick individuals. This comprehensive symptom review helps differentiate between viral and bacterial causes (which impacts treatment), provides guidance on managing dehydration, and determines when a local in-person visit or specific tests (like stool samples) might be necessary, especially for severe or prolonged cases.
Treatment & Management Options
The primary goals of gastroenteritis treatment are rehydration and symptom relief:
- Hydration (most crucial):
- Sip small, frequent amounts of clear fluids (water, oral rehydration solutions (ORS), clear broths, diluted clear juices).
- ORS is highly recommended to replenish electrolytes lost through vomiting and diarrhea.
- Avoid sugary drinks, caffeine, and alcohol, as they can worsen dehydration.
- Bland Diet: Gradually reintroduce food with easy-to-digest, low-fiber options like bananas, rice, applesauce, toast (BRAT diet). Avoid fatty, spicy, dairy, or highly fibrous foods initially.
- Rest: Allow your body to recover.
- Over-the-counter (OTC) Medications:
- Anti-diarrheal medications (e.g., loperamide, bismuth subsalicylate) may be used for adults with mild to moderate diarrhea, but consult a doctor first, especially if fever or bloody stools are present.
- Anti-nausea medications (e.g., bismuth subsalicylate) can help with nausea and vomiting.
- Antibiotics: Only prescribed by a doctor for specific bacterial infections and are not effective for viral gastroenteritis.
When to Seek Emergency Care
- Signs of severe dehydration: Decreased urination, severe thirst, dry mouth and skin, dizziness, confusion, extreme fatigue, sunken eyes, inability to keep down fluids.
- High fever (over 39°C/102.2°F or 102.5°F for children).
- Bloody or black, tarry stools.
- Severe, persistent abdominal pain that rapidly worsens.
- Persistent vomiting that prevents you from keeping down any fluids for more than 24 hours in adults or 12 hours in children.
- Signs of illness in infants, very young children, pregnant women, the elderly, or individuals with compromised immune systems.
- Recent travel to a high-risk area with severe or unusual symptoms.

FAQ
What's the best way to avoid getting stomach flu while traveling? Practice frequent handwashing, especially before eating and after using the restroom. Be mindful of food and water safety in different regions: drink bottled water, avoid ice, eat well-cooked food, and peel fruits yourself.
How long does stomach flu usually last? Most cases of viral gastroenteritis are short-lived, lasting 1-3 days. However, some viral or bacterial infections can last up to 10 days or even longer for parasitic infections.
When can I start eating solid food again after stomach flu? Once vomiting has stopped and your appetite returns, start with small amounts of bland, easy-to-digest foods like plain rice, toast, bananas, or applesauce. Avoid dairy, fatty, spicy, or high-fiber foods until your digestive system has fully recovered.
