Viral gastroenteritis, often called the stomach flu or stomach bug, is characterized by inflammation in the stomach and intestines due to a viral infection. It’s important to note that the stomach flu is not related to influenza, which affects the respiratory system. Food poisoning, on the other hand, results from consuming contaminated food or water. It encompasses over 250 different foodborne or waterborne illnesses.

Symptoms of viral gastroenteritis include nausea, vomiting, diarrhea, stomach cramps, muscle aches, weakness, appetite loss, low fever, headaches, and dizziness.

Food poisoning symptoms often overlap with those of the stomach flu. They may include stomach or intestinal cramps, diarrhea, fatigue, fever, chills, muscle aches, headaches, sweating, and thirst. While stomach flu symptoms typically appear within one to three days of viral exposure, food poisoning symptoms can manifest anywhere from a few hours to several weeks after consuming contaminated food.

Viral gastroenteritis is caused by viruses such as norovirus, rotavirus, adenovirus, and astroviruses. Transmission commonly occurs through direct contact with an infected person or by touching contaminated surfaces with traces of stool, saliva, or vomit.

Food poisoning, conversely, stems from ingesting food or water contaminated with bacteria, viruses, or, less frequently, parasites. Proper food handling and preparation are crucial for preventing food poisoning.

Diagnosis of viral gastroenteritis is often based on symptoms. Rapid stool tests can detect rotavirus and norovirus, though these tests may not be universally available. Food poisoning diagnosis considers symptoms, duration of illness, and recent food consumption. Diagnostic tests may be ordered based on the severity and specific symptoms.

Treatment for viral gastroenteritis focuses on increasing fluid intake, replenishing electrolytes, resting, and using over-the-counter medications to reduce fever. Most cases resolve within a few days, although symptoms can linger for up to 10 days or more.

Food poisoning treatment depends on the pathogen and symptom severity. Most cases resolve without treatment within a few days, but some may last longer. Treatment may involve fluid and electrolyte replacement, antibiotics (for bacterial infections), or anti-parasitic medications.

Home care for both illnesses includes consuming a bland diet, drinking plenty of fluids, gradually reintroducing solid foods, and avoiding dairy, caffeine, alcohol, sugar, fatty, and spicy foods for a period after recovery.

Medical attention is necessary if symptoms worsen or include bloody stool or vomit, inability to keep down fluids, diarrhea lasting more than three days, fever above 104 degrees Fahrenheit, or severe abdominal pain. These symptoms could indicate a more serious condition requiring professional medical care. Other health issues can mimic these illnesses, so consulting a doctor is recommended if you are unsure of the cause or if symptoms are severe.
