Most individuals with gastroenteritis will experience both diarrhea and vomiting, but some experience only one of these symptoms.
Gastroenteritis (gastro) is a bowel infection that causes diarrhoea (runny, watery poo) and sometimes vomiting. The vomiting may settle quickly, but the diarrhoea can last up to 10 days. Gastro can be caused by many different germs, although the most common cause of gastro is a viral infection.
The main symptoms of viral gastroenteritis are watery diarrhea and vomiting. The affected person may also have headache, fever, and abdominal cramps (“stomach ache”).
Unlike viral gastroenteritis, food poisoning is strictly based on what you eat. It can be caused by bacteria, parasites and viruses. And just like with the stomach flu, you may experience the same symptoms of nausea, vomiting, diarrhea, abdominal cramping and fever.
Overview. Viral gastroenteritis is an intestinal infection that includes signs and symptoms such as watery diarrhea, stomach cramps, nausea or vomiting, and sometimes fever.
The illness typically comes on suddenly. The infected person may feel very sick and vomit often, sometimes without warning, many times a day. Sometimes people infected with norovirus have no symptoms at all, but can still pass the virus to others.

How is gastroenteritis diagnosed? Your healthcare provider will perform an exam and ask about your medical history. Your healthcare provider will likely ask for a stool sample to determine the source of your illness and whether it's bacterial or viral.
Gastroenteritis is a very common condition which causes diarrhoea and vomiting. Gastroenteritis in adults is often caused by a virus (stomach bug) called norovirus, also known as the winter vomiting bug. Norovirus is the most common stomach bug in the UK.
Norovirus and rotavirus share many similarities. They cause many of the same symptoms, affect people of any age, and have a similar duration of symptoms. Often, the only means of diagnosis is through a stool sample test.
Stomach flu is a viral infection that affects the stomach and small intestine. It is also called viral gastroenteritis. The illness is usually brief, lasting 1 to 3 days.
nausea and vomiting that may last a day or two. diarrhoea which usually lasts one to three days, but can last up to ten days. stomach cramps and pain. fever (temperature over 37.5 C in adults and over 38 C in children).
Depending on the cause, symptoms usually take between one and three days to start. Symptoms usually last one to two days, or sometimes longer.
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.
Causes of Vomiting with Diarrhea
The illness starts with vomiting. Watery loose stools follow within 12-24 hours. On cruise ship outbreaks, the most common viral cause is Norovirus.
Signs and symptoms of norovirus infection may start suddenly and include: Nausea. Vomiting. Stomach pain or cramps.
Diagnostic methods for norovirus focus on detecting viral RNA (genetic material) or viral antigen. Diagnostic tests are available at all public health laboratories and many clinical laboratories, and most use reverse transcription- real-time polymerase chain reaction (RT-qPCR) assays to detect norovirus.
Most people develop viral gastroenteritis symptoms within 24 to 72 hours of exposure to a virus, while food poisoning symptoms can appear anytime within a few hours to weeks following exposure to a foodborne or waterborne pathogen.
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.
Norovirus. With norovirus — the most common cause of viral gastroenteritis in adults — you're contagious when you begin to feel ill. Symptoms usually appear within one to two days of exposure. Although you typically feel better after a day or two, you're contagious for a few days after you recover.
Vomiting persists more than two days. Diarrhea persists more than several days. Diarrhea turns bloody. Fever is more than 102 F (39 C) or higher.
Q: Can you have bacterial gastroenteritis with diarrhea as the only symptom? A: Symptoms of bacterial gastroenteritis vary in type and severity, and some people may experience diarrhea without other symptoms, such as abdominal pain or nausea.
If you experience sudden diarrhoea and/or vomiting, the best thing to do is to stay at home until you're feeling better. There's no treatment for norovirus, so you have to let it run its course. You don't usually need to get medical advice unless there's a risk of a more serious problem.
