Also known as ‘stomach flu’ or ‘gastro’, gastroenteritis is a common condition that affects the gut (the stomach and intestines) and is often highly infectious.

Gastro is triggered primarily by infections that lead to inflammation of the digestive system’s lining. It may result in nausea, diarrhea, stomach pain, and vomiting.

Although gastro is typically not serious, it can cause dehydration. Milder kinds can be treated at home with fluid intake. However, individuals who are older, younger, or have poorer immune systems are more likely to experience more severe illnesses.

Symptoms of Gastroenteritis

  • Diarrhea
  • Fever
  • Headaches
  • Lack of appetite
  • Vomiting
  • Nausea
  • Stomach pain

When to See a Doctor

If a child experiences dehydration or is unable to swallow a sip of fluids, consult a doctor right away (dry mouth, no urine for 6 hours or more, or lethargy).

If an adult or older kid experiences symptoms like fever, severe abdominal discomfort, blood in their diarrhea, or dehydration symptoms like thirst and decreased urine, lethargy, dry mouth, sunken eyes, or feeling dizzy while standing, they should consult a doctor.

Causes of Gastroenteritis

  • Parasites, such as giardia
  • Bacteria, such as salmonella
  • Toxins produced by bacteria
  • Chemicals, for instance, toxins in poisonous mushrooms
  • Viruses like the rotavirus and norovirus infections are by far the most prevalent causes

Diagnosis for Gastroenteritis

The doctor can diagnose gastro after talking to you and performing tests. To identify the organism causing your condition, your provider may order a stool test if the symptoms do not improve.

Treatment of Stomach Flu

Gastroenteritis often lasts for a few days and usually does not require treatment. Although it may not be safe for kids, medication for nausea or diarrhea can be helpful for adults. Antibiotics are seldom beneficial.

Drinking fluids is typically the most important treatment for gastroenteritis. For young children, frequent small sips are simpler than a huge amount consumed all at once. Even if you are vomiting, keep drinking regularly.

If you are feeling queasy, try to consume little bits of food frequently. Start with bland, simple things like plain crackers, bread, bananas, rice, and chicken when your appetite returns.

Avoid undiluted fruit juice, soft drinks, and sports drinks as well as milk and other dairy products because the sugar in these items may exacerbate the condition.

How to Prevent Gastroenteritis

  • Disinfect any potentially infectious surfaces or objects. Use a household cleanser with bleach as its primary ingredient.
  • Clothes or bedding that have been polluted should be washed separately on a hot cycle.
  • Avoid sharing utensils or cutlery while you or your child is sick.
  • Clean the area around the toilet or potty and flush away any poop or vomit.
  • Practice good food hygiene. For instance, make sure food is properly refrigerated, cook your food thoroughly, and never eat food past its use-by-date.
