What You'll Learn
Stomach flu is not the same as influenza
Although it is commonly called the stomach flu, gastroenteritis is not the same as influenza. The flu (influenza) is a respiratory illness that affects the nose, throat, and lungs. On the other hand, gastroenteritis affects the intestines, causing symptoms such as watery diarrhea, nausea, vomiting, stomach cramps, and occasional muscle aches or headaches.
The stomach flu, or viral gastroenteritis, is caused by a number of viruses, mainly norovirus, which accounts for over 50% of cases, and others like rotavirus. It can also be caused by bacteria such as salmonella and E. coli, or parasites such as giardia. The symptoms of the stomach flu include stomach pain, nausea, vomiting, and diarrhea. A low-grade fever, chills, and muscle aches can also be experienced. Symptoms can appear within 1-3 days of infection and can last from 1 to 14 days.
The flu, or influenza, on the other hand, is caused by the influenza virus and affects the upper respiratory tract. Symptoms of the flu include fever, congestion, muscle aches, and fatigue. More severe cases can lead to life-threatening illnesses like pneumonia. The flu is typically a more serious illness than the stomach flu, and it can be especially dangerous for older adults, infants, and people with weakened immune systems.
It is important to note that the stomach flu and influenza are caused by different viruses and have different symptoms. The stomach flu is often referred to as a "family affair" because it is highly contagious and can spread quickly among family members. It is important to practice good hygiene, such as frequent handwashing, to prevent the spread of the stomach flu.

Muscle aches are a common symptom
Although it's commonly referred to as the "stomach flu", gastroenteritis is not the same as influenza. Influenza is a respiratory illness that affects the nose, throat, and lungs. On the other hand, gastroenteritis affects the intestines, causing symptoms such as watery diarrhoea, nausea, vomiting, stomach cramps, and occasional muscle aches or headaches.
The symptoms of the stomach flu include stomach pain, nausea, vomiting, and diarrhoea. Muscle aches, low-grade fever, and chills are also common. Symptoms typically appear within 1-3 days of infection and can last anywhere from 1 to 14 days. In most cases, the illness resolves on its own without medical intervention. However, it is important to prioritise rest and hydration to manage symptoms and prevent dehydration.
To relieve muscle aches and other symptoms of the stomach flu, there are some home remedies that may be helpful. Applying a low-temperature heating pad or a warm heat pack to the stomach can help relax the muscles in the digestive tract. Drinking rice water, which is high in electrolytes, can also aid in rehydration. It is recommended to drink plenty of fluids and get lots of rest, aiming for at least 7 to 8 hours of sleep each night.
In summary, muscle aches are a common symptom of the stomach flu, along with other symptoms such as nausea, vomiting, diarrhoea, and fever. The stomach flu is caused by viruses such as norovirus and rotavirus, and it can be effectively managed with rest and hydration.

The illness is caused by a viral infection
The stomach flu, or viral gastroenteritis, is caused by a viral infection that attacks the gastrointestinal system. It is important to note that the stomach flu is not the same as influenza, which affects the respiratory system. The stomach flu is caused by a number of viruses, mainly norovirus, which accounts for more than 50% of cases, and others like rotavirus, adenovirus, astrovirus, and caliciviruses.
Viral gastroenteritis causes inflammation and irritation of the intestines, leading to symptoms such as watery diarrhea, nausea, vomiting, stomach cramps, occasional muscle aches, and low-grade fever. Symptoms typically appear within 1-3 days after infection and can range from mild to severe. They usually last just a day or two but can occasionally persist for up to 14 days.
The viruses that cause stomach flu can be found in the vomit or diarrhea of infected individuals. The illness spreads through close contact with infected people or by consuming contaminated food or water. It can also be transmitted by touching surfaces handled by infected individuals.
To prevent the spread of stomach flu, it is crucial to practice good hygiene, including frequent hand washing, disinfecting surfaces, and separating laundry loads when someone in the household is sick. Vaccines are also available in some countries to immunize infants and young children against rotavirus, one of the common causes of viral gastroenteritis.
While most cases of stomach flu do not require medical treatment, it is important to focus on hydration and rest to manage symptoms. Over-the-counter oral rehydration solutions can help prevent dehydration, and anti-nausea or anti-diarrhea medications may be recommended to ease symptoms. In severe cases, hospitalization and intravenous fluids may be necessary.

Treatment focuses on rehydration and rest
Stomach flu, or viral gastroenteritis, is a viral infection that attacks the gastrointestinal system. It is not the same as influenza, which affects the respiratory system. Symptoms of stomach flu include nausea, abdominal pain, watery diarrhea, vomiting, stomach cramps, and occasional muscle aches.
Treatment for stomach flu focuses on rehydration and rest. Rehydration is critical because the illness can cause a rapid loss of fluids and electrolytes through sweating, diarrhea, vomiting, and fever. Dehydration can make symptoms worse and lead to lethargy, headaches, and other serious health complications.
To rehydrate, it is recommended to take small and frequent sips of fluids every 30 minutes. Suitable fluids include water, unsweetened hot or iced tea, coconut water, broths, and oral rehydration solutions. Oral rehydration solutions like Pedialyte contain sodium, potassium, and chloride—the main electrolytes lost through vomiting and diarrhea. Bone broth is also recommended as it contains collagen, which can aid in gut repair and provide soothing benefits for the digestive system. It is important to avoid sugary foods and drinks, as well as dairy, alcohol, caffeine, and fatty or spicy foods, as these can be irritating to the digestive system and worsen diarrhea.
In addition to rehydration, rest is essential for recovery. This includes getting plenty of sleep and taking it easy between trips to the bathroom. Keeping yourself comfortable and relaxed by watching your favorite TV show or movie can also aid in the recovery process.
In summary, treating stomach flu involves rehydration with fluids and electrolytes, as well as rest and relaxation, to alleviate symptoms and prevent dehydration.

Prevention includes handwashing and vaccination
Although it's called the "stomach flu", the condition is not the same as influenza, which affects only the respiratory system. Stomach flu, or viral gastroenteritis, is a viral infection that attacks the gastrointestinal system. The most common cause of stomach flu is the norovirus, which is highly contagious and spread through the fecal-oral route. This means that the virus is transmitted when stool or vomit from an infected person makes its way into another person's mouth. This can happen when an uninfected person touches a contaminated surface and then touches their mouth, or when they consume food handled by an infected person.
The symptoms of stomach flu include watery, usually non-bloody diarrhea, nausea, vomiting, stomach cramps and pain, occasional muscle aches or headaches, and a low-grade fever.
To prevent the spread of stomach flu, it is important to practice good hygiene and vaccination. Here are some specific ways to do this:
- Wash your hands thoroughly and frequently, especially after using the toilet, changing diapers, and before preparing or eating food. Use hand sanitizer after being in public places.
- Teach your children to wash their hands properly, especially after using the toilet.
- Use household cleaning products to disinfect frequently touched surfaces and objects, such as doorknobs, handles, countertops, sinks, toilets, computer keyboards, and phones.
- Keep your distance from people who are sick, especially newborns and infants, who are more vulnerable to infection.
- Get vaccinated. A vaccine against gastroenteritis caused by rotavirus is available in some countries, including the United States. This vaccine is given to children in the first year of life and has been shown to be effective in preventing severe symptoms of the illness.
