Most gastro illnesses should pass within two or three days, but in some types of gastro, such as a giardia infection, symptoms can last for months if left untreated - and can recur. If you think you might have giardia, see your Doctor.
Research suggests that as many as 30% to 40% of people who suffer from a sudden case of gastroenteritis go on to develop post-infectious IBS. Many pathogens responsible for gastroenteritis can also cause post-infectious IBS, including norovirus and Giardia, a protozoa often found in contaminated food or water.
Depending on the cause, viral gastroenteritis symptoms may appear within 1-3 days after you're infected and can range from mild to severe. Symptoms usually last just a day or two, but occasionally they may last up to 14 days.

“It's resistant to many common disinfectants,” Hall said. CDC recommends using bleach to kill it, including chlorine bleach or hydrogen peroxide. That's why health departments often require restaurants to use bleach to clean countertops and kitchen surfaces. It's also able to survive being dried out.
Persistent diarrhea and vomiting can lead to abdominal pain, stomach cramps, loss of appetite, and dehydration. In young children, diarrhea and vomiting can cause an electrolyte imbalance, which is very dangerous and can lead to death if untreated.
Gastroenteritis (gastro) is a bowel infection that causes diarrhoea (runny, watery poo) and sometimes vomiting. The vomiting may settle quickly, but the diarrhoea can last up to 10 days. Gastro can be caused by many different germs, although the most common cause of gastro is a viral infection.
Testing data from NSW Health shows that the number of rotavirus cases, the most common cause of gastroenteritis, is at some of the “highest levels of the last decade”. The first two weeks of 2023 saw 197 cases of rotavirus reported, up significantly from the average 40 cases in the same period.
Unlike viral gastroenteritis, food poisoning is strictly based on what you eat. It can be caused by bacteria, parasites and viruses. And just like with the stomach flu, you may experience the same symptoms of nausea, vomiting, diarrhea, abdominal cramping and fever.
How is gastroenteritis diagnosed? Your healthcare provider will perform an exam and ask about your medical history. Your healthcare provider will likely ask for a stool sample to determine the source of your illness and whether it's bacterial or viral.

Stomach bugs, also called gastroenteritis, are very common in young children and can cause vomiting, diarrhea and sometimes a fever. Gastroenteritis typically lasts in the neighborhood of three to seven days, but sometimes it can be shorter and, unfortunately, sometimes it lasts longer.
Causes can include overeating, intestinal infections, stress and anxiety, and chronic gastrointestinal disorders. Stomach pain and nausea are usually short-lived and get better on their own. However, people with persistent symptoms should see a doctor for an evaluation.
Rotavirus and adenovirus are both common causes of stomach flu in young children. Rotavirus can last for about 3–8 days, and adenovirus can last for about 5–7 days. Young children who are sick are most at risk of developing dehydration. Parents and caregivers should look for signs of dehydration in children.
What is stomach flu (gastroenteritis)? Gastroenteritis is inflammation (irritation) of your intestines. People usually call it a “stomach bug” or “stomach flu,” even though it's not limited to just influenza. Although most people report stomach pain, gastroenteritis can also involve your small intestines and colon.
"There are some symptoms more specific to COVID-19, like loss of taste and smell, cough, or chest pains," explained Dr. Elliott, adding, "Patients do not generally get these symptoms with the stomach flu."
Gastritis tends to affect the lining of the stomach, whereas gastroenteritis affects the intestines. Gastritis is inflammation, or irritation, of the stomach lining. Gastroenteritis, on the other hand, is inflammation of the intestine, or the stomach and the bowel. Gastritis can be acute or chronic.
