Stomach Flu (Viral Gastroenteritis): Symptoms, Causes, Diagnosis, and Treatment

• Dr. Satheesh Rao

Stomach flu, also known as viral gastroenteritis, is a highly contagious illness that affects the stomach and intestines, causing symptoms like vomiting, diarrhoea, and abdominal pain. While the term "stomach flu" is commonly used, it is important to note that this condition is caused by a viral infection, not the flu virus. If you're in Mysore and experiencing severe symptoms, it’s essential to seek the expertise of the best gastroenterologist in Mysore for diagnosis and treatment.

Symptoms of Stomach Flu

The symptoms of viral gastroenteritis can vary in intensity, but common signs include:

• Diarrhoea: Watery and frequent bowel movements are hallmark signs of the illness.
• Vomiting: Often accompanies diarrhoea and can lead to dehydration if not managed properly.
• Abdominal cramps: Painful cramping or bloating in the stomach area.
• Fever: Mild to moderate fever may be present.
• Nausea: A general feeling of queasiness that can contribute to vomiting.
• Headache and muscle aches: These are often experienced alongside gastrointestinal symptoms.

If you experience any of these symptoms, particularly if they persist for more than 24 hours, consulting with the best gastroenterologist in Mysore is crucial to rule out any underlying conditions.

Causes of Stomach Flu

Viral gastroenteritis is caused by several different viruses, most commonly:

1. Norovirus: The leading cause of stomach flu, especially in adults. It spreads quickly in crowded places like schools, nursing homes, and hospitals.
2. Rotavirus: More common in children, rotavirus is a leading cause of viral gastroenteritis in infants and toddlers.
3. Adenovirus: Typically causes gastroenteritis in children.
4. Astrovirus: Less common, but can still cause outbreaks in both children and adults.

These viruses are typically transmitted through contaminated food, water, or close contact with infected individuals. Poor hygiene and improper sanitation can increase the risk of contracting the virus. For residents of Mysore, the best gastroenterologist in Mysore can help provide advice on preventing the spread of these viruses in your community.

How is Stomach Flu Diagnosed?

The diagnosis of stomach flu primarily relies on evaluating the symptoms and medical history. If you are concerned about your symptoms, it’s important to see a healthcare professional who can determine the cause. A visit to the best gastroenterologist in Mysore may involve:

• Physical Examination: The doctor will examine your stomach area for signs of pain, tenderness, or bloating.
• Stool Tests: To identify the specific virus causing the illness, a stool sample may be required.
• Blood Tests: In cases where dehydration is a concern, blood tests may be conducted to assess electrolyte levels.

A precise diagnosis from a skilled gastroenterologist is essential, especially to differentiate viral gastroenteritis from other digestive disorders such as bacterial infections or food poisoning.

Treatment of Stomach Flu

While there is no specific antiviral medication to treat viral gastroenteritis, most cases resolve on their own within a few days. The main goal of treatment is to manage symptoms and prevent complications such as dehydration. Here are some general treatment guidelines recommended by the best gastroenterologist in Mysore:

1. Hydration: Replacing fluids lost through vomiting and diarrhea is critical. Oral rehydration solutions (ORS) are ideal for restoring electrolytes. In severe cases, intravenous fluids may be needed.
2. Dietary Adjustments: Avoid solid foods during the initial stages of illness. Once vomiting subsides, you can gradually introduce bland foods like toast, rice, or bananas.
3. Over-the-Counter Medications: Anti-diarrheal medications may be suggested for symptom relief, but they should only be used under the guidance of a doctor, as they may not be appropriate for everyone.
4. Rest: Adequate rest helps the body recover and supports the immune system in fighting off the virus.

While most cases of stomach flu are mild and resolve without medical intervention, it's always best to consult with a healthcare provider if symptoms are severe or persistent. The best gastroenterologist in Mysore can provide personalized treatment plans based on the severity of your condition.

Prevention of Stomach Flu

Prevention is key to avoiding viral gastroenteritis. The following precautions can help reduce your risk:

• Wash your hands thoroughly with soap and water, especially after using the restroom or before eating.
• Avoid contaminated water and food: Be cautious of drinking untreated water or consuming food from unreliable sources.
• Disinfect surfaces: Viruses can survive on surfaces for a prolonged period, so regular cleaning and sanitizing are important, especially in homes with young children or elderly people.
• Avoid close contact: If you’re infected, stay home to avoid spreading the virus to others.

For individuals in Mysore looking for expert guidance, consulting with the best gastroenterologist in Mysore can offer tailored advice on preventing infections in your area.

When to Seek Medical Attention

In most cases, viral gastroenteritis improves within a few days without the need for medical treatment. However, if you experience any of the following warning signs, it's essential to consult the best gastroenterologist in Mysore:

• Severe dehydration: Symptoms include dizziness, dry mouth, excessive thirst, and reduced urine output.
• High fever: A fever over 102°F (39°C) may indicate a more serious infection.
• Persistent vomiting: If vomiting doesn’t stop or prevents you from keeping fluids down.
• Blood in stool or vomit: This may indicate a more serious infection or complication.
