What Are The Signs Of Stomach Flu?

Nov 04, 2023 By Madison Evans

Direct contact with an infected individual or ingesting tainted food or drink is the most common transmission of viral gastroenteritis, often known as stomach flu. If your health is typically good, you shouldn't have too many issues. Anyone may become sick from a virus that causes gastroenteritis, but young children, the elderly, and those with compromised immune systems are more at risk. There is currently no treatment for viral gastroenteritis. Thus prevention is key. It's best to avoid consuming anything that might have been tampered with, but frequent and thorough hand washing is essential.

What Is The Stomach Flu Exactly?

The stomach flu describes a virus infection of the small intestine and larger intestine. The term "viral gastroenteritis" may also describe this condition. The typical course of this illness lasts between one and three days.

How Does It Occur?

Several different viruses, including the Norwalk virus, adenoviruses, and rotaviruses, may cause gastroenteritis. In many cases, the virus may be identified in a person's body fluids before any outward symptoms appear. The only known transmission route is via direct contact with an affected person. Infections may be passed from person to person by kissing, shaking hands, or other forms of close physical contact, as well as through the consumption of tainted food or the use of infected drinking vessels. The infection brings on inflammation of the digestive tract. When there is inflammation in the GI system, the stomach and intestines don't function as well as they might. Occasionally, food may stimulate digestion and cause it to work more quickly.

What Are The Signs?

The following are signs that you could be suffering from the stomach flu:

  • nausea
  • vomiting
  • Pain in the Stomach
  • diarrhea
  • Flu-like symptoms, but nothing too serious
  • tiredness
  • chills
  • empty stomach
  • I was experiencing discomfort in one's muscles.

How Is It Treated?

To start, take some time off to rest your digestive system. One way to do this is fast, meaning subsisting only on water or other clear liquids. After your condition has improved, you may return to eating soft, bland foods. If you have often been vomiting, it is best to sip on little quantities of liquid frequently. Drinking even a small amount at once may have more nausea and vomiting than usual. How you hydrate is essential. If you're feeling sick and water is all you can keep down, that's OK. Replacing the salt and potassium you've lost is especially crucial if you've often been vomiting or for a lengthy period. Consult your physician if you need clarification on whether or not the rehydration drinks or sports drinks you're using provide the necessary minerals.

What Is The Duration Of The Effects?

Stomach flu often lasts between three and seven days. While normal bowel motions should return within a week, it may take up to two weeks. Dehydration is a serious complication of stomach flu. If you lose a lot of fluids due to things like vomiting and diarrhea, it's conceivable. Severe dehydration may need the administration of intravenous fluids (IV). Infants and the elderly are at increased risk of serious complications from dehydration.

What Is The Incubation Period For The Stomach Flu?

As a rule, symptoms won't appear until a few days after first contact. The case may be different from virus to virus, however. Symptoms of norovirus, rotavirus and sapovirus often show within 2–3 days after exposure, but symptoms of astrovirus may present 4–5 days after contact, according to a study from 2013. (Reliable Source). Even though symptoms of an adenovirus infection may not appear until 2-14 days after infection, they often appear during the first 5-6 days. Symptoms of the stomach flu often last between three and five days. Infections may linger for longer in high-risk people. The most contagious time for a virus is between the beginning of symptoms and several days after they have faded. One such virus is rotavirus, which may be passed around before any symptoms show.


As the viruses that cause gastroenteritis differ from the influenza viruses that cause respiratory illnesses in the fall and winter, the term "viral gastroenteritis" is more accurate. A wide variety of viruses may cause viral gastroenteritis. When it comes to frequency of occurrence, rhinovirus is unrivaled. It is possible to infect people with viral gastroenteritis while you have symptoms and for a few days after they have faded. But the virus may live on in your poop for weeks after you've stopped showing symptoms. This is why it's so important to thoroughly wash your hands before consuming food, particularly after using the restroom. Gastroenteritis is an inflammation of the gastrointestinal system. While the flu is generally the focus of the phrase "stomach bug" or "stomach flu," these terms may apply to gastroenteritis. Stomach pain is a common symptom of gastroenteritis.
