What is intestinal flu?
Intestinal flu is a viral infection of the gastrointestinal tract. The medical name is viral gastroenteritis, and other common names include stomach flu, or a 24-hour or 48-hour “bug.” It is the second most common illness affecting American families. Intestinal flu involves irritation and inflammation of the gastrointestinal tract and is not actually a form of flu or influenza.
The hallmark symptoms of intestinal flu are nausea, vomiting and diarrhea. Similar gastrointestinal symptoms involved with intestinal flu can also result from a variety of other conditions, such as bacterial food poisoning, alcohol intoxication, and irritable bowel syndrome. Intestinal flu is often mistaken for these other conditions and vice versa.
Symptoms of true intestinal flu or viral gastroenteritis often subside within 24 to 48 hours if you refrain from eating solid foods and get plenty of fluids. If intestinal flu causes serious dehydration, hospitalization and rehydration with intravenous fluids may be necessary.
Intestinal flu is quite common and extremely contagious. It can occur in any age group or population. It tends to affect infants, children, the elderly, and people with compromised immune systems more seriously than healthy adults.
Intestinal flu can lead to serious complications, such as dehydration. Seek prompt medical care if you have a chronic illness, a compromised immune system, or symptoms of intestinal flu that do not improve after a day or two. Contact your physician or health care provider right away if your newborn baby has symptoms of intestinal flu.
Seek immediate medical care (call 911) if you, your child, or someone you are with, have symptoms of intestinal flu accompanied by lethargy, change in alertness, inability to produce tears, major rectal bleeding, or lack of urination.
