Depending on the cause, viral gastroenteritis symptoms may appear within one to three days after you're infected and can range from mild to severe. Symptoms usually last just a day or two, but occasionally they may persist as long as 10 days.
Is diarrhea a symptom of cold or flu?
Symptoms of flu include sore throat, fever, headache, muscle aches and soreness, congestion, and cough. Swine flu in particular is also associated with vomiting and diarrhea.
Most of the symptoms that are caused by the flu virus could also just as easily be the result of a cold virus infection, according to the CDC. Some differences: the flu virus is more likely to cause fever — and a higher fever, at that. Some flu sufferers also have intestinal symptoms, such as vomiting or diarrhea.
Diarrheal infections are highly contagious. They can spread from person to person via dirty hands, contaminated food or water, and some pets. Most cases are contagious for as long as a person has diarrhea, but some infections can be contagious for even longer.
If you change the food you eat, that can sometimes cause an upset stomach or diarrhea. Sometimes hormones can cause your digestive process to slow down, and at times that can lead to diarrhea. Every pregnant woman has these hormonal changes, but some will experience diarrhea early in their pregnancy from those changes.
Influenza is a respiratory illness. Although the term “stomach flu” is sometimes used to describe vomiting, nausea, or diarrhea, these illnesses are caused by certain other viruses, bacteria, or possibly parasites, and are rarely related to influenza. Why would influenza virus infection cause gastrointestinal symptoms?
Most acute episodes of diarrhea are due to viral infections and last three to five days. Prolonged diarrhea -- lasting more than four to six weeks -- usually is due to an underlying gastrointestinal disease, the most common of which are diseases that cause inflammation and malabsorption of food.
It is not related to influenza, the real flu.The stomach bugs are highly contagious and are primarily spread through the fecal-oral route. Technically, you need to swallow the virus to get the illness. When a person has viral gastroenteritis, massive quantities of the viruses are present in their feces and vomit.
In most cases, over-the-counter medication can be helpful in stopping an occasional bout of diarrhea — especially traveler's diarrhea, which may result from ingesting contaminated food or water while abroad. Over-the-counter options include Imodium (loperamide) and Pepto-Bismol or Kaopectate (bismuth subsalicylate).
Gradually begin to eat bland, easy-to-digest foods, such as soda crackers, toast, gelatin, bananas, rice and chicken. Stop eating if your nausea returns. Avoid certain foods and substances until you feel better. These include dairy products, caffeine, alcohol, nicotine, and fatty or highly seasoned foods.
The exact reasons why diarrhea occurs during your period aren't fully understood, but it is quite common and often tied to menstrual cramps. Believed to be at the root of the cause are prostaglandins, chemicals released during your period that allow the uterus, and thus the intestines, to contract.
Vomiting and diarrhea are common symptoms of the stomach flu and food poisoning. Treatment for nausea, vomiting, and/or dehydration is the same for both illnesses. Antidiarrheal medications may not be recommended for some causes of food poisoning. Food poisoning usually may last up to 10 days, depending upon the cause.
Viral gastroenteritis can be spread from person to person or by touching a contaminated surface, but you can also get viral gastroenteritis from sewage-contaminated food or water, or meals prepared or handled by an infected person. (Hence all those "wash your hands" signs in restaurant bathrooms.)
How Long Does a Typical "Stomach Flu" Last? Most people who get a stomach virus experience symptoms for 1-3 days but diarrhea may persist for as long as 10 days with some viruses. Typically, vomiting should stop within about 24 hours if you are caring for yourself and treating it properly.
The symptoms of ciguatera poisoning can last for 1 to 2 weeks. Exactly how long they last will depend on the amount of poison you have in your body. The symptoms can come back any time you eat an affected fish. The symptoms of scombroid poisoning usually last for 24 hours or less.
Stomach flu (viral enteritis) is an infection in the intestines. It has an incubation period of 1 to 3 days, during which no symptoms occur. Once symptoms appear, they usually last for 1 to 2 days, although symptoms may linger for as long as 10 days.
Signs You Have Food Poisoning. Cramps in your stomach and gut, diarrhea, and vomiting may start as early as 1 hour after eating tainted food and as late as 10 days or longer. It depends on what is causing the infection.
Most cases of food poisoning last about 1 to 2 days and symptoms resolve on their own. If symptoms persist longer than that, the affected person should contact their health-care professional. Cyclospora infections may be difficult to detect and diarrhea may last for weeks.
The symptoms may include:
- loss of appetite.
- nausea and vomiting.
- abdominal pains and cramps.
- blood in your stools.
Symptoms of rotavirus — the leading cause of viral gastroenteritis in infants and young children — usually appear one to three days after exposure. But you're contagious even before you develop symptoms, and up to two weeks after you've recovered.
A sore throat, pneumonia, an ear infection, or a cough can sometimes cause tummy trouble as well. Severe pain also can be caused by a urinary tract infection or a blocked intestine. Infection by bacteria or a parasite, heartburn, irritable bowel disease, or inflammatory bowel disease also can cause abdominal pain.
