What is Stomach Flu? Causes, Symptoms, Treatment & Prevention

What is Stomach Flu?

Stomach flu is a common illness that affects the stomach and intestines. Doctors often call it viral gastroenteritis. Many people use the term “stomach flu,” but it is not the same as the flu that affects your lungs. Instead, stomach flu is caused by viruses that make your stomach and bowels upset. Because it spreads easily, knowing the symptoms of stomach flu and how to prevent stomach flu is important for everyone.

Common Symptoms

Usually, stomach flu symptoms start suddenly. They can last for a few days. However, most people get better without problems. Common signs include:

  • Watery diarrhea
  • Stomach pain or cramps
  • Nausea or vomiting
  • Fever
  • Headache
  • Muscle aches
  • Feeling tired
  • Sometimes, you may also feel chills or lose your appetite. Because these symptoms can be severe, it is important to rest and drink fluids.

    Causes and How It Spreads

    Most cases of stomach flu are caused by viruses. Norovirus and rotavirus are the most common. These germs spread easily from person to person. For example, you can get stomach flu by:

  • Touching surfaces with the virus and then touching your mouth
  • Eating food or drinking water that has the virus
  • Being close to someone who is sick
  • Because the virus is strong, it can live on surfaces for days. Therefore, washing your hands often helps stop the spread.

    Diagnosis

    Doctors usually diagnose stomach flu by asking about your symptoms. Most of the time, tests are not needed. However, if you have severe symptoms or blood in your stool, your doctor may order tests. These tests can check for other causes or rule out bacteria and parasites. According to the CDC, most cases are mild and do not need special tests.

    Treatment Options

    There is no specific cure for stomach flu. Instead, treatment for stomach flu focuses on easing symptoms. Most people recover at home. Here are some helpful steps:

  • Drink plenty of fluids to prevent dehydration
  • Eat small, bland meals like toast or rice
  • Rest as much as possible
  • Avoid dairy, caffeine, and fatty foods until you feel better
  • Sometimes, children or older adults may need extra care. If you cannot keep fluids down, you may need to see a doctor. The World Health Organization suggests using oral rehydration solutions for severe dehydration.

    Prevention Tips

    Because stomach flu spreads easily, taking steps to prevent it is important. You can lower your risk by:

  • Washing your hands often with soap and water
  • Cleaning surfaces, especially in kitchens and bathrooms
  • Staying home when you are sick
  • Not sharing food, drinks, or utensils
  • Washing fruits and vegetables before eating
  • Making sure food is cooked well
  • For young children, vaccines for rotavirus can help prevent some types of stomach flu.

    When to See a Doctor

    Most people get better from stomach flu without medical help. However, you should see a doctor if you:

  • Have signs of dehydration, such as dry mouth or dark urine
  • Cannot keep any fluids down
  • Have a high fever that does not go away
  • See blood in your stool or vomit
  • Feel very weak or dizzy
  • Children, older adults, and people with weak immune systems should be extra careful. If you are worried, it is always best to ask a healthcare professional.
