Your doctor will likely diagnose viral gastroenteritis (stomach flu) based on symptoms, a physical exam and sometimes on the presence of similar cases in your community. A rapid stool test can detect rotavirus or norovirus, but there are no quick tests for other viruses that cause gastroenteritis.
Treatment is meant to keep you hydrated and avoid complications. It’s important to not lose too many nutrients, such as sodium and potassium. Your body needs these in certain amounts in order to function properly.
If you have a serious case of bacterial gastroenteritis, you may be admitted to the hospital and given fluids and salts intravenously.
Antibiotics are usually reserved for the most severe cases.
Home remedies for mild cases
If you have a milder case, you may be able to treat your illness at home. Try the following:
Drink fluids regularly throughout the day, especially after bouts of diarrhea.
Eat little and often, and include some salty foods.
Consume foods or drinks with potassium, such as fruit juice and bananas.
A few ingredients you may have at home can help keep your electrolytes balanced and treat diarrhea. Avoid eating dairy, fruit, or high fiber foods to keep diarrhea from getting worse.
Over-the-counter (OTC) medications that neutralize your stomach acid can help. Medications that treat symptoms like diarrhea, nausea, and abdominal pain can help ease the stress and pain of the infection.
