However, if you understand the differences between the symptoms of both (that is, food poisoning vs. a virus), youâll have an easier time finding the right treatment that will get you back on your feet.
Once you know what you have, you can work towards getting over your sickness as fast as possible.
Both food poisoning and the flu can cause similar symptoms: nausea, diarrhea, stomach aches, and vomiting are common with both.
Given that so many of these symptoms are the same, how do you know if its food poisoning or the flu? Well, it turns out that there are some key differences between the two illnesses.
The Differences between Food Poisoning and the Flu
When trying to determine if you have the flu or food poisoning, there are a few subtle differences that can help you figure out which one is causing your sickness.
Food poisoning is a result of eating food that is contaminated with bacteria, viruses, or parasites. Often, food that is improperly handled, cleaned, or cooked can make you sick. Viruses, on the other hand, can be spread much more easily, either through physical contact or even through the air. As well, not washing your hands can lead to the flu and other viral illnesses.
One thing which makes it difficult to determine whether you have a food poisoning or a virus is that food can actually be contaminated with viruses, soâin some casesâyou could have both. However, more often, food poisoning is due to bacteria. Here are some differences between food poisoning symptoms and flu symptoms that can help you figure out which is likelier to be causing your misery.
|Food Poisoning||Flu or similar virus|
|Similar symptoms||Diarrhea, nausea, vomiting, fever||Diarrhea, nausea, vomiting, fever|
|Different symptoms||Fatigue, lost appetite, severe abdominal pain||Headaches, muscle aches, cramps|
|Onset of Symptoms||One hour to three weeks after eating contaminated food||One to two days after exposure|
|Duration||Usually lasts from one to 10 days||Usually lasts one to two days, but can last up to 10|
|Complications||Dehydration; potential for kidney damage, liver damage, blood vessel damage, paralysis, or miscarriages||Dehydration|
While the flu and food poisoning can seem similar, food poisoning can cause some more severe symptoms and complications in many cases. For babies, elderly people, and people with compromised immune systems, both the flu and food poisoning can pose a serious health risk and cause for concern.
If you want to know whether you have a stomach bug or food poisoning, it can also help to know which viruses and contaminants cause the specific illness. You may be able to narrow the cause of your illness down to something you ate or were exposed to.
Some common viruses and food contaminants are:
|Hepatitis A||Food poisoning|
|Norovirus||Flu-like illness, although it can contaminate food too|
|E. coli||Food Poisoning|
|Influenza Type B||Flu|
Food Poisoning vs. a Stomach Bug: How to Tell Them Apart
When trying to figure out if you are suffering from food poisoning or a stomach bug, there are some key things which can help you quickly pinpoint the culprit.
Food poisoning has a more rapid onset. If you eat contaminated food, you can become sick in as little as an hour or two. If you go out to a restaurant and are throwing up a few hours later, then itâs more likely that you have food poisoning.
Both food poisoning and stomach bugs can cause abdominal pains, but they are usually more severe with food poisoning. With a virus, you may have a dull ache in your stomach, but you probably wonât get the sharp, stabbing pains that often come with food poisoning.
If your entire family comes down with a sickness at the same time, then itâs likely from something you all ate. Viruses, on the other hand, often spread from person to person, which means you will have different onsets of sickness than with food poisoning.
Both sicknesses can last up to 10 days, but food poisoning is more likely to clear up in a very short amount of time. If you feel better after a few hours or a after a nightâs sleep, thereâs a good chance it was a stomach bug.
All Food Poisonings Are Not the Same
Once you have narrowed down your sickness to food poisoning, you may be wondering how long does food poisoning last?
Well, it depends. Food poisoning can caused by a variety of bacteria, viruses, and other contaminants. There is no single type of food poisoning; rather, there are many different types of food poisoning, and symptoms, illness duration, and contaminated products can differ with each type.
For instance, salmonellosis is commonly caused by undercooked chicken and other meats, while giardia infections usually occur from uncooked vegetables and fruits. However, both of these types of food poisoning could occur with any type of food, assuming there has been cross-contamination during processing, handling, or cooking.
As well, food poisoning can cause very different symptoms depending on the type. Cholera infections are usually over in less than a day and symptoms clear up afterwards. However, botulism can cause severe symptoms if left untreated, including difficulty speaking, fatigue, and even paralysis. As well, other types of food poisoning can cause kidney damage, liver damage, miscarriages, and even death.
This is why if you do believe that you have food poisoning, you shouldnât jump to conclusions. Some people may have had food poisoning before and had it clear up very quickly, leading them to mistakenly think that every case isnât serious and doesnât need to be treated. On the other hand, some people may rush to the doctor at the first sign of nausea, when thereâs nothing they can do but wait for their body to fight off the virus.
Food Poisoning vs. the Flu: When to Worry
So when should you rush off to the doctor, and when should you just sit back and wait for your illness to resolve itself? It can be hard to figure out whatâs an actual emergency. Seek medical attention immediately if any of the following circumstances apply to you:
- Your symptoms last for more than a few days;
- There is blood present in your stool;
- You are experiencing a fever;
- You are experiencing severe stomach/abdominal pains;
- You have been eating wild mushrooms;
- You are pregnant; or
- You are experiencing symptoms that are not associated with regular food poisoning or the flu, such as bleeding, severe pain, or vision distortion.
If your symptoms are limited to diarrhea, moderate abdominal pain, nausea, and vomiting, then you can wait a few days to see if your illness resolves. Often, both food poisoning and the flu will resolve on their own.
Wash vegetables, fruits, and other foods before eating them.
How to Prevent Food Poisoning and the Flu
If you already have the flu or food poisoning, then itâs too late to prevent it. However, once you have experienced the horrible symptoms of food poisoning or viruses, you will certainly want to make sure they never happen again. Here are some steps you should take to protect yourself from the flu:
- Always wash your hands before meals, after being in public, and after using the washroom.
- Do not share food, utensils, drinks, cosmetics, or personal care items (e.g., lip balm).
- If someone is sick, avoid close contact with them as much as possible.
- Get the right amount of rest, eat healthy, and exercise regularly.
When it comes to the flu vs. food poisoning the latter is the tougher of the two to prevent, but here are some tips that might help:
- Always cook meat and fish to their required internal temperature.
- Use a meat thermometer for cooking any meat.
- Wash vegetables, fruits, and other foods before eating them.
- Never eat food that has been sitting out for more than a couple hours.
- Serve food at their intended temperatures.
- After handling raw meat, wash your hands and clean utensils, surfaces, and dishware.
- Refrigerate leftovers and eat them within a couple days.
- Avoid eating out at restaurants or fast-food places on a regular basis.
- If youâre traveling, research safety precautions for food and water in your destination spot.
When you have either food poisoning or the flu, nothing is more important
than to drink plenty of fluids.
Tips to Take Care of Your Stomach
Both the flu and food poisoning are, frankly, awful, but there are some flu and food poisoning remedies that you can use to help treat these illnesses.
After coming down with a stomach bug, the bacteria in your gut may be compromised or overtaken by âbadâ bacteria. If youâre experiencing digestive upset for more than a few days after becoming ill, taking a probiotic can help return your stomach to normal. Look for probiotics that contain a high amount of bacterial strains and colony-forming units (CFUs). As well, fermented foods and drinks, such as sauerkraut, kombucha, and kefir, can help replenish your gut with good bacteria.
When you have either food poisoning or the flu, nothing is more important than to drink plenty of fluids. Both conditions can cause dehydration as a result of diarrhea or vomiting, so itâs important to replenish yourself with water, but also with sports drinks such as Gatorade, as they have electrolytes and sugar that can help hydrate your body and restore lost nutrients.
Limit your diet:
The flu can cause a lot of digestive problems. If you have a stomach bug, do not eat foods which are known to aggravate indigestion and cause stomach upset, including spicy foods, beans, dairy products, and alcohol.
Donât take anti-diarrhea medication:
Your body has diarrhea for a reasonâitâs trying to flush out viruses and bacteria from your body. When you take medication to stop diarrhea, you end up reducing your bodyâs ability to overcome the illness. If you really want to use these medications, speak with your doctor first.
It can be difficult to tell the difference between food poisoning vs. the flu, but when you are sick to your stomach, knowing these difference can help you get better faster. Both cause many of the same symptoms, but by understanding the type of illness you have, you can be more prepared to recover and youâll also know when you need to see your doctor. Luckily, as bad as these illnesses are, they often resolve on their own. Get plenty of rest, drink lots of water, and wash your hands!
