Stomach flu

Stomach Flu

The stomach flu, also known as gastroenteritis, is a condition that causes irritation and inflammation of the stomach and intestines (the gastrointestinal tract). Despite its common name, the stomach flu is not caused by the influenza virus. The most common causes of the stomach flu are viral, bacterial, or parasitic infections.

Causes

The stomach flu is most commonly caused by viruses such as norovirus, rotavirus, adenovirus, and astrovirus. Bacterial infections such as E. coli, Salmonella, and Campylobacter can also cause gastroenteritis, as can parasites like Giardia.

Symptoms

Symptoms of the stomach flu can include nausea, vomiting, diarrhea, abdominal pain, and fever. Symptoms usually appear within 1-2 days of infection and can last for several days.

Treatment

Treatment for the stomach flu primarily involves managing symptoms and preventing dehydration. This can include drinking plenty of fluids, eating a bland diet, and taking over-the-counter medications to manage symptoms. In severe cases, hospitalization may be required for IV fluids and medication.

Prevention

Prevention of the stomach flu involves practicing good hygiene, such as washing hands regularly and thoroughly, especially after using the toilet and before handling food. Vaccines are available for some causes of gastroenteritis, such as rotavirus.
