Gastroenteritis

Gastroenteritis: Introduction

Gastroenteritis is a general word and a symptom of any condition, disorder or disease that causes irritation and inflammation of the gastrointestinal tract. Gastroenteritis is most frequently caused by a viral infection and is also often referred to as viral gastroenteritis, the stomach flu or the 24 or 48 hour bug.

The hallmark symptoms of gastroenteritis are nausea, vomiting and diarrhea. Gastroenteritis can also lead to dehydration. The underlying disorder, disease or condition that is causing gastroenteritis can also cause complications. For more details about symptoms and complications, see symptoms of gastroenteritis.

In addition to a gastrointestinal viral infection, gastroenteritis can also result from a variety of other conditions. These include irritable bowel syndrome, food poisoning, traveler's diarrhea, or a toxic ingestion. A toxic ingestion occurs after eating a substance that is toxic, such as a poisonous plant or mushroom.

Gastroenteritis can occur in any age group or population. Gastroenteritis can be a symptom of a mild condition, such as indigestion or stress a moderate condition, disorder or disease, such as a side effect of medication, such as antibiotics or chemotherapy. Gastroenteritis can also occur in serious, even life-threatening conditions, including food poisoning and anthrax.

Some causes of gastroenteritis, such as viral gastroenteritis, are contagious. Other causes are not contagious, including irritable bowel syndrome and toxic ingestion. Depending on the cause, gastroenteritis can be short-term and disappear quickly, such as when gastroenteritis occurs after a single episode of alcohol intoxication. Gastroenteritis can also be recurring over a longer period of time, such as when gastroenteritis is due to irritable bowel syndrome.

Diagnosing gastroenteritis and its root cause begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination. Diagnosis may also include a complete blood count, which can help to determine if an infectious process, such as food poisoning is present.

A stool sample may be tested to determine if food poisoning or bacterial infection is the cause of the gastroenteritis. This is called a stool culture and sensitivity, which can also determine the most effective antibiotic to use to treat gastroenteritis due to a bacterial infection.

A chemistry panel is a blood test that can evaluate if gastroenteritis has lead to the complication of dehydration. An urinanalysis can also help to determine dehydration.

Making a diagnosis may also include performing a variety of other tests to help to diagnose other potential underlying diseases, conditions or disorders, such as irritable bowel syndrome or a toxic ingestion. If the gastroenteritis does not resolve quickly, tests can include additional blood tests and imaging tests such as X-ray, CT scan, ultrasound or occasionally endoscopy.

In an endoscopy procedure, a special lighted instrument is inserted into the area or areas of the gastrointestinal system that are suspected to be the cause of the gastroenteritis and other symptoms. This instrument, called an endoscope, takes pictures of the digestive tract and/or sends images to a computer monitor.

A diagnosis of gastroenteritis and its cause can easily be delayed or missed because gastroenteritis may be intermittent and for other reasons. For information on misdiagnosis, refer to misdiagnosis of gastroenteritis.

Treatment of gastroenteritis involves diagnosing and treating the underlying disease, disorder or condition that is causing it. Some conditions can be quickly and successfully treated, while others, such as irritable bowel syndrome may require more difficult to treat. For more information on treatment, refer to treatment of gastroenteritis. ...more »
