Often incorrectly referred to as the 'stomach flu', gastroenteritis is a condition in which a person experiences temporary inflammation of the stomach and/or intestines. This inflammation leads to diarrhea and/or vomiting, as well as complications from these symptoms, such as abdominal pain, dehydration, and fatigue.
Crampy pains in your tummy (abdomen) are common. Pains may ease for a while each time you pass some diarrhoea. A high temperature (fever), headache and aching limbs sometimes occur.
The main symptoms include vomiting and diarrhea. It is usually not serious in healthy people, but it can sometimes lead to dehydration or cause severe symptoms.
Your doctor will likely diagnose viral gastroenteritis (stomach flu) based on symptoms, a physical exam and sometimes on the presence of similar cases in your community. A rapid stool test can detect rotavirus or norovirus, but there are no quick tests for other viruses that cause gastroenteritis.
Gastroenteritis is often mistaken for stomach flu although it is actually an inflammation of the lining of the intestines caused by a virus, bacteria or parasites. Symptoms of gastroenteritis include diarrhea, abdominal pain, vomiting, headache, fever and chills.
Although you typically feel better after a day or two, you're contagious for a few days after you recover. The virus can remain in your stool for up to two weeks or more after recovery. Children should stay home from school or child care for at least 48 hours after the last time they vomit or have diarrhea.
Symptoms of gastroenteritis usually last 24 to 72 hours. However, they can last up to 10 days if the stomach flu began while you were travelling abroad or upon your return. Persons with gastroenteritis are usually contagious when showing symptoms, and most particularly so when symptoms are severe.
How long do the effects last? Stomach flu rarely lasts longer than 1 to 3 days. However, it may be 1 to 2 weeks before your bowel habits are completely back to normal. Dehydration is a potentially serious complication of stomach flu.
During gastroenteritis, it is important to eat as normally as possible. In fact, eating helps the lining of the intestine to heal quickly and allows the body to regain strength. On the contrary, not eating prolongs diarrhea. Start by eating small amounts of food.
Gastroenteritis is a short-term illness triggered by the infection and inflammation of the digestive system. Symptoms can include abdominal cramps, diarrhoea and vomiting. Some of the causes of gastroenteritis include viruses, bacteria, bacterial toxins, parasites, particular chemicals and some drugs.
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.
Key points about gastroenteritis
Bacterial gastroenteritis is sometimes treated with antibiotics. If severe cases are not treated, they can lead to severe dehydration, neurological problems, kidney failure, and even death.
Yogurt may help prevent or treat diarrhea
Certain types of yogurt contain friendly bacteria, also known as probiotics, which may help prevent or treat diarrhea.
The type of gastrointestinal symptoms is a clue to the type of infection. Viral infection generally produces diarrhea without blood or mucus and watery diarrhea is a prominent symptom. Conversely, a person is more likely to have diarrhea with mucus and blood in bacterial diarrhea.
Gastroenteritis usually comes on suddenly and sticks around for just a short time. The illness typically lasts less than a week.
Gastroenteritis is a common condition that triggers diarrhoea, sickness and tummy pain.
However, the key distinction is time: The symptoms of a stomach bug will take 12 to 48 hours to develop, while the symptoms of food poisoning typically develop much faster, usually with 6 hours of consuming an infected dish. Another common difference between the two is the length of illness.
Gastritis may occur suddenly (acute gastritis) or appear slowly over time (chronic gastritis). In some cases, gastritis can lead to ulcers and an increased risk of stomach cancer. For most people, however, gastritis isn't serious and improves quickly with treatment.
Adults and older children should seek medical advice if their symptoms include a fever, severe abdominal pain, blood in their diarrhoea or signs of dehydration, such as thirst and decreased urination, lethargy, dry mouth, sunken eyes or feeling faint when standing.
Self-Check/At-Home
Diagnosing viral gastroenteritis is usually done after a review of the symptoms. Most people will be able to decide by themselves from prior experience, and from knowing that an illness is “going around," that symptoms are being caused by a common virus.
Gastroenteritis is an inflammation of the gastrointestinal tract in both the stomach and the small intestine. The most common form of gastroenteritis is viral.
