Stomach Flu: Causes, Symptoms, Treatment

Stomach flu, also known as viral gastroenteritis, is a common condition characterized by inflammation of the stomach and intestines. Despite its name, it’s not caused by the influenza virus. This article delves into the causes, symptoms, and treatment options for stomach flu to help you weather the storm of this temporary but often uncomfortable illness.


  • Viral Infections:

Stomach flu is frequently caused by viruses, with norovirus and rotavirus being common culprits. These viruses are highly contagious and can spread through contaminated food, water, or surfaces.

  • Bacterial Infections:

Certain bacteria, such as Salmonella or Escherichia coli (E. coli), can also lead to gastroenteritis, causing symptoms similar to stomach flu.

  • Parasitic Infections:

Parasites like Giardia lamblia can cause stomach flu, often through the ingestion of contaminated food or water.


Gastrointestinal Distress:

  • Nausea and Vomiting: Persistent feelings of nausea often accompanied by vomiting.
  • Diarrhea: Watery or loose stools are common symptoms of stomach flu.

Abdominal Pain and Cramping:

  • Individuals may experience discomfort or cramping in the abdominal region.

Fever and Body Aches:

  • A low-grade fever and general body aches can accompany stomach flu.


  • Excessive fluid loss from vomiting and diarrhea can lead to dehydration. Signs include dark urine, dry mouth, and dizziness.


Fluid Replacement:

  • Stay hydrated by drinking clear fluids, such as water, clear broths, or electrolyte solutions, to replace lost fluids and electrolytes. For further information refer to a Best Gastroenterologist in Lahore.


  • Allow your body to rest and recover by getting plenty of sleep.

Diet Modifications:

  • Gradually reintroduce bland foods like bananas, rice, applesauce, and toast (BRAT diet) as tolerated.

Over-the-Counter Medications:

  • Antiemetics (for nausea) and anti-diarrheal medications can provide symptomatic relief. However, consult a healthcare professional before using them, especially in certain populations.

Avoid Irritants:

  • Steer clear of caffeine, alcohol, and spicy foods that may exacerbate gastrointestinal symptoms.

Medical Attention:

  • Seek medical attention if symptoms are severe, persist for more than a few days, or if there are signs of dehydration.


  • Hand Hygiene:

Wash hands thoroughly with soap and water, especially after using the bathroom and before handling food.

  • Food Safety:

Practice safe food handling, including thorough cooking and avoiding raw or undercooked foods.

  • Environmental Hygiene:

Disinfect surfaces regularly, especially in shared spaces and during outbreaks.


Stomach flu can be a challenging but typically temporary ordeal. With proper care, including hydration, rest, and, when necessary, medical attention, most individuals can successfully navigate the symptoms and recover fully. To get medical assistance you can visit your Gastroenterologist in Karachi.
