What Is Stomach Flu? Symptoms, Causes, Treatment, and Recovery Guide
Often mistaken for seasonal influenza, stomach flu is actually a viral infection of the digestive tract known as viral gastroenteritis. It causes inflammation of the stomach and intestines, leading to diarrhea, vomiting, and stomach cramps.
According to the Top Gastroenterologist in Chennai, most cases are mild and resolve within a few days with proper hydration and supportive care.
What is stomach flu and what causes
it?
Stomach flu is commonly caused by viruses such as norovirus and rotavirus. These viruses spread through contaminated food, water, surfaces, or close contact with an infected person. Poor hand hygiene and consuming improperly prepared food increase the risk of infection. Although bacteria and parasites can also cause gastroenteritis, they are not considered "stomach flu. "
What are the symptoms of stomach flu?
Symptoms usually appear 12 to 48 hours after exposure and may last for one to three days, although some infections can persist longer. Common symptoms include:
✅ Watery diarrhea
✅ Nausea and vomiting
✅ Stomach cramps
✅ Low-grade fever
✅ Muscle aches
✅ Headache
✅ Fatigue
✅ Mild dehydration
Severe dehydration may cause dizziness, dry mouth, reduced urination, and confusion, especially in young children and older adults.
How is stomach flu diagnosed?
In most cases, doctors diagnose stomach flu based on symptoms, recent food or travel history, and a physical examination. Laboratory tests, including stool analysis, are generally recommended only if symptoms are severe, prolonged, bloody, or occur during suspected outbreaks. Blood tests may be performed if significant dehydration or electrolyte imbalance is suspected.
Stomach flu treatment
There is no specific antiviral medication for most cases of viral gastroenteritis. The primary goal of stomach flu treatment is preventing dehydration by drinking oral rehydration solutions, water, and clear fluids. Eating small amounts of bland foods as tolerated can help recovery.
Antibiotics are not effective against viral infections and should only be used when a bacterial infection is confirmed. Your doctor may prescribe anti-nausea medications in selected cases.
Stomach flu recovery
Most healthy adults recover completely within one to three days, while children, older adults, and people with weakened immune systems may take longer. Rest, adequate hydration, and gradually returning to a normal diet support faster stomach flu recovery.
When should you see a doctor for stomach flu?
Seek medical attention if symptoms last longer than three days, there is blood in the stool, persistent vomiting prevents fluid intake, high fever develops, or signs of severe dehydration occur.
