24-Hour Stomach Virus Symptoms

Viral gastroenteritis is often referred to as the stomach flu or a 24-hour stomach virus. In most cases, the stomach flu clears up on its own after one to three days. In some cases, it can last as long as 10 days. Viral gastroenteritis can be caused by one of several viruses and is most common from October through April. Washing your hands often and avoiding contact with people who are sick are the most effective ways to prevent a stomach virus.

Diarrhea

One of the most common symptoms of a stomach virus is diarrhea. It may be watery and very frequent. If you see blood in your stools, seek medical care, as bloody diarrhea is not a symptom of a simple stomach flu. If watery, frequent diarrhea lasts longer than a day or two, call your doctor. Diarrhea can cause dehydration, so drink a lot of clear liquids, but frequently, in small quantities.

Abdominal Cramping

Abdominal cramping and pain may range from mild to severe. While the cramping and gas pains that go along with viral gastroenteritis are common, if the pain starts suddenly or is accompanied by chest or shoulder pain, seek medical care. If the pain lasts longer than a week, call your doctor, as this could be a symptom of a more serious illness.

Nausea and Vomiting

Nausea, with or without vomiting, is usually present during a stomach virus. Drinking only a sip at a time of very cold water or other clear beverages can help you stay hydrated. Drinking more than a sip at a time can cause you to vomit again. If you are not able to keep any fluids down for more than a day, or if you have been vomiting for more than two days, call your doctor. Call immediately if you see blood in your vomit.

Fever

Viral gastroenteritis can sometimes cause a fever, along with chills, sweating, muscle aches and fatigue. Avoid taking ibuprofen, as this can make nausea worse. Take acetaminophen to reduce your fever and ease your discomfort. If your fever is above 104 degrees F, call your doctor for advice.
