Where is the gastroenteritis found?

Gastroenteritis is inflammation of the stomach and intestines. It can cause symptoms ranging from mild to severe. A virus, bacterium, or parasite can cause gastroenteritis. When it’s caused by a type of bacteria, it’s called bacterial gastroenteritis.

How do you investigate gastroenteritis?

A doctor will diagnose gastroenteritis by first taking a complete history of your symptoms. Often, lab test are not needed to diagnose this condition. However, if you have persistent fever or blood in your stool, stool study tests may be ordered. Rarely, ultrasounds, X-rays, or CT scans may be helpful in diagnosis.

What labs are ordered for gastroenteritis?

General laboratory evaluation Consider investigating patients with low-grade fever, nausea, vomiting, abdominal pain, and extreme dehydration by evaluating serum electrolytes, urea, creatinine, amylase, complete blood cell (CBC) count, and abdominal imaging studies.

How is the diagnosis and treatment of gastroenteritis made?

Diagnosis is clinical or by stool culture, although polymerase chain reaction testing and immunoassays are increasingly used. Treatment is symptomatic, although some parasitic and some bacterial infections require specific anti-infective therapy. Gastroenteritis is usually uncomfortable but self-limited.

What causes gastroenteritis in immunocompromised patients?

In immunocompromised patients, additional viruses (eg, cytomegalovirus, enterovirus) can cause gastroenteritis. Bacterial gastroenteritis is less common than viral. Bacteria cause gastroenteritis by several mechanisms.

How is gastroenteritis spread from person to person?

Gastroenteritis is inflammation of the lining of the stomach and small and large intestines. Most cases are infectious, although gastroenteritis may occur after ingestion of drugs and chemical toxins (eg, metals, plant substances). Acquisition may be foodborne, waterborne, or via person-to-person spread.

How often does gastroenteritis occur in the US?

Most cases are infectious, although gastroenteritis may occur after ingestion of drugs and chemical toxins (eg, metals, plant substances). Acquisition may be foodborne, waterborne, or via person-to-person spread. In the US, an estimated 1 in 6 people contracts foodborne illness each year.

What are the symptoms of parasitic gastroenteritis?

Subsequent inflammation and disruption of the gut mucosa lead to watery diarrhea, inadequate digestion of food, and malabsorption of nutrients [18]. The course of parasitic gastroenteritis is longer than both bacterial and viral gastroenteritis with symptoms lasting up to 4 weeks, even if the infection is cleared.

What are the causes of acute infectious gastroenteritis?

Fig. 1 Overview of acute infectious gastroenteritis. Acute gastroenteritis is a disease affecting the stomach and small and large intestine (central panel). Causes of infectious gastroenteritis include bacterial, viral, and/or parasitic pathogens (I). These pathogens can be invasive and cause cell damage and produce toxins.
