Viral gastroenteritis, more commonly referred to as the stomach virus or stomach bug, is a condition characterized by inflammation of the stomach and intestines, according to MedlinePlus. Many viruses can cause the stomach bug, including norovirus and rotavirus, both of which are very common in children. Symptoms, including nausea, vomiting and diarrhea, usually appear within 48 hours of exposure to the virus and can last several days. Severe stomach viruses can be life threatening; those affected should see a physician for medical evaluation.
Stay Hydrated
Preventing dehydration is the primary goal while the virus runs its course. Constant vomiting and diarrhea upsets the body's fluid and electrolyte balance, and in severe cases, can lead to hospitalization. Fluids, such as sports drinks and oral rehydration solutions, sold in the children's section of the grocery store are good choices. If you cannot tolerate larger amounts of fluids, try sucking on ice chips or taking small sips of clear soda such as ginger ale. The National Digestive Diseases Information Clearing House advises contacting a physician if you experience signs of dehydration, including excessive thirst, dark urine, severe weakness and lethargy.
Stick With a Bland Diet
Once you are able to eat again, ease back into it slowly. FamilyDoctor.org recommends starting with the BRAT diet, which includes bananas, rice, applesauce and toast. This diet helps by binding stools and providing potassium to help replace lost nutrients. Slowly introduce other bland foods such as crackers or boiled potatoes. Do not stay on the BRAT diet for longer than 24 to 48 hours unless you are under a physician's direction, as the diet does not provide adequate nutrition.
Avoid Stomach Irritants
Certain foods can worsen stomach virus symptoms. MayoClinic.com recommends avoiding caffeine, dairy products, alcohol and fatty foods until you are feeling better. Spicy foods can aggravate an upset stomach and cause a painful burning sensation on the trip back up. Sugary foods, such as ice cream, candy or soda, can make diarrhea worse, especially in children. MayoClinic.com explains that water is not absorbed well in children with a stomach virus and may worsen symptoms.
Use Caution with Medications
Do not use anti-diarrheal medications without consulting your physician first, as they can increase the length of the infection, explains MedlinePlus. Diuretics can increase the risk of dehydration. However, ff you are taking diuretics for a medical reason, do not stop taking them unless directed to do so by your doctor. Do not try to treat yourself with leftover antibiotics, as they are ineffective against a stomach virus.
