Stomach flu is also called gastroenteritis. It occurs when there is an inflammation of the stomach and small and large intestines. It is caused by a variety of virus. However according to the Centers for Disease control it is not caused by influenza viruses. In most cases it is not serious unless you are unable to drink enough fluids and you become dehydrated. The elderly and those with a compromised immune system are at a greater risk of complications. Learning to recognize the warning signs is an important step in managing this condition.
Common Symptoms
The Centers for Disease Control state that the most common symptoms are watery diarrhea, nausea and vomiting. This may be accompanied by abdominal cramps or a stomach ache. The Mayo Clinic states that in the case of stomach flu there is no blood in the diarrhea. If you do have blood, you may have an infection instead of a virus. These symptoms tend to occur within a few days of exposure to the virus and can last for up to ten days.
Other Symptoms
Additional symptoms of gastroenteritis include headache and fever. You may also experience fatigue, muscle aches and a loss of appetite. Your symptoms can range from mild to severe. If you are unable to drink or keep down enough fluid you may become dehydrated. At this stage it is important to drink enough fluids to help avoid complications.
Complications
If dehydration occurs you will need to be hospitalized and be treated with intravenous fluids. Your doctor will need to correct the lack of fluid and resulting electrolyte imbalance. If dehydration is left untreated it can become fatal. Signs of dehydration include a dry or sticky mouth, low or no urine output, urine that is dark yellow, no tear production, sunken eyes, a loss of elasticity in the skin and feeling lethargic. Your blood pressure may be low and your heart rate may be irregular.
