  • contaminated food or water

Diagnosis & Treatment

General Measures

  • In most cases, this disorder will be self-treated at home. Call your health provider if symptoms are severe or if they cause you any concern.
  • Your health care provider may do a physical exam. Medical tests may include studies of blood and stool.
  • Treatment usually involves rest and fluids. There is no specific drug for viral infections.
  • It is not necessary to keep persons with gastroenteritis away from others. Try to avoid close contact if possible.
  • Hospital care may be needed if dehydration is severe.

Medications

Drugs are usually not needed for treatment. If symptoms are severe or prolonged, you may take antinausea and antidiarrhea drugs such as Pepto-Bismol or loperamide.

Activity

Get extra rest until diarrhea, nausea, vomiting, and fever are improved. Be sure to have access to a toilet or bedpan.

Diet

  • suck ice chips or drink small amounts of clear fluids often
  • once symptoms improve, try a diet of complex carbohydrates (rice, wheat, potatoes, bread, cereal, and lean meat such as chicken); milk and dairy products usually do not need to be limited
  • avoid high-sugar foods or fatty foods for a few days

Notify Our Office If

  • symptoms of gastroenteritis last longer than 2 days
  • symptoms continue or worsen after treatment
  • blood or mucus appears in the stool
