In most cases, people with viral gastroenteritis get better on their own without medical treatment. You can treat viral gastroenteritis by replacing lost fluids and electrolytes to prevent dehydration. In some cases, over-the-counter medicines may help relieve your symptoms.
Stomach viruses are often mild and go away on their own in 1 to 3 days. Babies, older adults, or people who have low immune systems should see the doctor right away. This can help prevent their infection from getting worse.
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.

Most individuals with gastroenteritis will experience both diarrhea and vomiting, but some experience only one of these symptoms. Diarrhea is often very watery (type 7 on the Bristol stool chart), and can be bloody if the source of gastroenteritis is bacterial.
“It can persist on surfaces for several days even at room temperature,” Hall said. Soap and water can wash it away, but it takes really hot water to kill it.
Sometimes people infected with norovirus have no symptoms at all, but can still pass the virus to others.

If you have a stomach bug that is lasting for weeks (or months), it could be post-infectious irritable bowel syndrome.
Rotavirus: Symptoms of this virus can last between 3 and 8 days. However, it is less common in the U.S. due to vaccinations. Astrovirus: Symptoms of this virus can last between 1 and 4 days. Adenovirus: Symptoms of this virus can last between 1 and 2 weeks.

Different strains of the virus exist.
Why does stomach flu hit at night? In some people, the stomach flu symptoms may be more pronounced at night due to their circadian rhythm. At night an increase in immune system activity releases infection-fighting chemicals. These can cause inflammation that make you feel worse as you battle your flu.
Avoid milk and dairy products, caffeine, alcohol, nicotine, and fatty or highly seasoned foods for a few days. Remember that norovirus infection is highly contagious. Avoid contact with others as much as possible during illness and for several days after recovery. Wash your hands and disinfect surfaces and objects.
Acute appendicitis is one of the most common pediatric abdominal emergencies. Early diagnosis is vital for a positive outcome. However, it may initially present with diarrhea and vomiting, mimicking acute gastroenteritis, thus delaying prompt surgery.
