If you have diarrhoea, you will experience an increase in the volume, wateriness or frequency of your bowel movements. Diarrhoea episodes are often caused by a stomach bug (gastroenteritis) and clear up on their own in a few days. However, there are many other causes of diarrhoea.
Gastroenteritis is a very common condition that causes diarrhoea and vomiting. It's usually caused by a bacterial or viral tummy bug. It affects people of all ages, but is particularly common in young children.
With gastroenteritis, the main symptoms you probably have are watery diarrhea and vomiting. You might also have stomach pain, cramping, fever, nausea, and a headache. Because of diarrhea and vomiting, you also can become dehydrated.
The main symptoms of gastroenteritis include diarrhoea and feeling or being sick. These usually come on suddenly. You may also get tummy pains or cramps and have other symptoms such as a fever. Most people feel better within a week.
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.
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.
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.
Most individuals with gastroenteritis will experience both diarrhea and vomiting, but some experience only one of these symptoms. Diarrhea is often very watery (type 7 on the Bristol stool chart), and can be bloody if the source of gastroenteritis is bacterial.
As viral gastro is very infectious, people with symptoms should not go to work or attend child care centres, kindergartens or schools until 48 hours after symptoms have stopped.
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.
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).
Schedule a doctor's visit for an adult with these symptoms:
Diarrhea lasts more than two days without improvement. Excessive thirst, dry mouth or skin, little or no urination, severe weakness, dizziness or lightheadedness, or dark-colored urine, which could indicate dehydration. Severe abdominal or rectal pain.
The following are red flags: Dry mucous membranes (dry mouth) Decreased skin turgor. Altered mental status.
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.
What is stomach flu (gastroenteritis)? Gastroenteritis is inflammation (irritation) of your intestines. People usually call it a “stomach bug” or “stomach flu,” even though it's not limited to just influenza. Although most people report stomach pain, gastroenteritis can also involve your small intestines and colon.
Viral gastroenteritis can be highly infectious so it can spread very easily. It spreads when a person comes in contact with the vomit or faeces (poo) of an infected person, including: person-to-person contact, for example shaking hands with someone who has been sick and has the virus on their hands.
How is it treated? The most important thing to do is to rest the stomach and intestine. You can do this by not eating solid food for a while and drinking only clear liquids. As your symptoms go away, you can start eating soft bland foods that are easy to digest.
Most of the time, diarrhea is simply your gut's way of getting rid of a harmful invader, like a bacteria or virus. However, in some cases, diarrhea is caused by a malfunction of the gut, as is the case with inflammatory bowel disease. Many viruses can cause diarrhea.
Gastroenteritis is an illness that may cause nausea, vomiting, and diarrhea. It can be caused by bacteria or a virus. You will probably begin to feel better in 1 to 2 days. In the meantime, get plenty of rest and make sure you do not become dehydrated.
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.
Although acute diarrhea generally resolves on its own, treating with IMODIUM® products relieves symptoms more quickly than letting diarrhea run its natural course. Speak to your physician if you have any questions or concerns.
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.
When you have gastroenteritis, your body eliminates large quantities of water and mineral salts that are essential to your body's proper functioning. It is important to drink plenty of fluids and replenish mineral salts to prevent dehydration.
