Viral Gastritis
Find out more about how you can treat viral gastritis
Often called the stomach flu even though it has nothing in common with the flu (influenza) and does not affect
the stomach, viral gastritis is the second most common illness after the common cold. A number of viruses cause
gastritis or inflammation of the large and small intestines; however influenza is not one of them. Viruses that
commonly cause gastritis include rotaviruses, adenoviruses, caliciviruses, astroviruses, Norwalk virus, and
Noroviruses. Other bacterial infections such as Salmonella or E. Coli and parasites such as Giardia may cause
similar symptoms.
The main symptoms of viral gastroenteritis include watery diarrhea and vomiting. Other symptoms include headache,
fever, abdominal cramps, excessive sweating, joint stiffness and chills. Symptoms usually begin 1 to 2 days
following infection with a virus that causes gastroenteritis and the symptoms might last up to ten days.
Viral gastritis is not a serious illness is not a serious disease for most people, although it can become serious
for people who get too dehydrated from vomiting and diarrhea. In addition, infants, young children, the elderly,
and the disabled are at greater risk for serious dehydration and might require hospitalization for treatment. Signs
of severe dehydration include dizziness, faintness, dry mouth, low urine output, chapped and cracked lips, sunken
appearance to the eyes, and confusion. Viral gastritis is usually spread through contact with contaminated food,
beverage, and close contact with infection persons and is highly contagious. Viral gastritis outbreaks often occur
in crowded settings such as schools, day care facilities and nursing homes. It may also spread rapidly in large
adult group settings such as cruise ships and campgrounds. Viral gastritis occurs everywhere, and rotavirus is most
common in infants and young children. Adenoviruses and astroviruses affect young children most, while Norwalk and
Noroviruses are more common causes in older children and adults.
Preventing severe dehydration caused by rapid loss of fluids from vomiting and diarrhea is the single most
important aspect of treatment for gastritis. Families with infants and young children should always keep oral
rehydration solutions at home. These solutions provide liquid, sugar, and minerals intended to prevent dehydration
and are available in most pharmacies without a prescription. Allowing the intestinal tract to rest by not eating
for a few hours, sipping small amounts of clear liquids, and gradually reintroducing bland foods such as broth,
toast, apples, bananas, apples and rice are all good steps to take after and during the illness. Also, avoid dairy
products, caffeine and alcohol for at least a week after full recovery. Get plenty of rest. Antibiotics, which have
no effect on viruses, should not be prescribed unless directed by a doctor.
To prevent future infections of gastritis, try frequent hand washing, avoiding contaminated food and beverages, and
disinfecting contaminated surfaces and prompt washing of soiled clothing.
