New Delhi: The change of season can bring with it a unique set of challenges, one of which is the increased risk of gastrointestinal issues like stomach flu and food poisoning. While they may share some common symptoms, it's crucial to recognise the differences between stomach flu and food poisoning. This article will empower you with the knowledge to distinguish between the two and seek appropriate care when needed.
Stomach Flu (Viral Gastroenteritis)
Stomach flu, more accurately termed viral gastroenteritis, is primarily caused by viral infections. Viruses such as norovirus, rotavirus, and adenovirus are the usual culprits behind stomach flu cases. These viruses are highly contagious and can spread through various means, including direct contact with an infected person, consuming contaminated food or water, or touching contaminated surfaces and then touching your mouth. Stomach flu earns its name due to the inflammation it triggers in the stomach and intestines. It is essential to remember that stomach flu is not the same as influenza or the seasonal flu that affects your respiratory system.
Food Poisoning
Food poisoning, on the other hand, results from consuming contaminated food or liquids. The contamination can come from harmful bacteria, parasites, toxins, or chemicals. This contamination can occur during food production, processing, or handling. Some well-known bacteria notorious for food poisoning include Salmonella, E. coli, and Campylobacter. The symptoms of food poisoning occur as your body's reaction to these harmful microorganisms and the toxins they produce.
Recognising the symptoms
Stomach Flu: Stomach flu typically presents with a range of symptoms that include nausea, vomiting, diarrhea, abdominal cramps, and occasionally a low-grade fever. The onset of symptoms is often sudden and can vary in intensity but generally subside within a few days.
Food Poisoning: Food poisoning can manifest with a diverse array of symptoms, largely depending on the specific contaminant ingested. Common symptoms include nausea, vomiting, diarrhea (which can sometimes be bloody), abdominal pain, fever, and muscle aches. Unlike stomach flu, where the onset is often rapid, food poisoning symptoms might take a few hours or even days to appear after consuming contaminated food.
Key differences
Onset and Duration: Stomach flu tends to strike suddenly, with symptoms appearing within a relatively short time frame after exposure to the virus. However, these symptoms generally resolve within a few days (1 to 3 days). Food poisoning symptoms, on the other hand, can appear within hours or days after consuming contaminated food and can persist for varying durations, ranging from a few hours to several days.
