Yes, gastroenteritis, commonly known as the stomach flu or stomach bug, can cause fever as one of its symptoms. Gastroenteritis is typically caused by viral, bacterial, or parasitic infections that lead to inflammation of the stomach and intestines.

Fever is a common immune system response to infections, including those that cause gastroenteritis. The body’s defense mechanism fights off the invading pathogens, which can result in an elevated body temperature.

In addition to fever, other symptoms of gastroenteritis often include nausea, vomiting, diarrhea, abdominal pain or cramps, and sometimes muscle aches. The severity and duration of symptoms can vary depending on the cause of the infection and the individual’s overall health.

If someone experiences symptoms of gastroenteritis, especially if they persist for more than a few days, if there is severe dehydration, or if the fever is high or accompanied by other concerning symptoms, it’s advisable to seek medical attention. Proper hydration and, if necessary, medical treatment can help manage the symptoms and prevent complications associated with gastroenteritis.
