An intestinal virus occurs when you acquire harmful bacteria from contact with another person or drinking contaminated water. Intestinal viruses are the primary cause of severe diarrhea, according to the University of Maryland Medical Center. The most common viruses that cause an intestinal infection include astroviruses, rotaviruses, noroviruses and enteric adenoviruses. A viral intestinal infection doesn't cause long-term harm to most people. If diagnosed with an intestinal virus, your doctor will recommend a modified diet to treat your symptoms.
Intestinal Virus
An intestinal virus is also commonly called the stomach flu, or medically referred to as viral gastroenteritis. The stomach flu causes infection and inflammation in the stomach and the intestines, resulting in digestive symptoms. Symptoms develop within four days after coming in contact with the virus. Common symptoms include low-grade fever, nausea, vomiting, abdominal cramps, pain, watery diarrhea and stomachaches. You should call your doctor if you are unable to keep any food or liquid down, you notice blood in your vomit or diarrhea, or you have a fever above 101.5 degrees.
Diet Modification
Before you attempt to change your diet, talk it over with your physician. Stop eating and drinking for a few hours until your stomach settles. Continuing to eat and drink can aggravate your intestines, causing your symptoms to worsen. Suck on ice chips or take small sips of water, clear soda or sports drinks. Ease back into eating solid foods gradually. Eat small portions often that are bland and easy to digest. Suggested foods by MayoClinic.com include bananas, soda crackers, toast, gelatin, chicken and rice. Avoid dairy products, nicotine, and fatty or highly seasoned foods while you still have symptoms.
Yogurt Consideration
Eating yogurt may help repair any damage to the lining of your intestines and may shorten the duration of your illness, according to AskDrSears.com. Yogurt contains helpful bacteria that are needed for healthy digestion. Eating two cups of low-fat, plain yogurt daily can help restore normal digestion and bowel movements. Avoid yogurt that is high in fat and contains a lot of sugar because these substances can increase your diarrhea symptoms.
Dehydration
Dehydration is the most common complication from an intestinal virus. Signs of dehydration include pale skin, fatigue, dry mouth, dry skin and extreme thirst. If you develop these symptoms, visit a local emergency room for further evaluation. Dehydration can lead to further complications, such as death.
