You had a wonderful family dinner, but now, a few hours later, everyone is feeling unwell and rushing to the bathroom. Symptoms like diarrhea, nausea, and vomiting are hitting everyone, and some are experiencing fever, chills, and headaches. You’re likely wondering: is it a stomach bug going around, or could it be food poisoning from something you ate?
It’s common to confuse Food Poisoning Or Stomach Bug because their symptoms can be quite similar. To help clear up the confusion, we’ll explore the key differences between these two common ailments and provide guidance on what to do when you’re feeling sick.
Key Differences Between Food Poisoning and Stomach Bug
“The main difference between food poisoning and a stomach bug lies in how quickly symptoms appear,” explains Dr. LeRon Jackson, a family medicine physician. “Food poisoning typically causes rapid onset of diarrhea and vomiting, usually within three to six hours after consuming contaminated food. In contrast, a stomach bug develops more gradually, with vomiting and diarrhea symptoms potentially appearing 12 to 24 hours after infection. Often, someone with a stomach bug will first feel generally unwell and nauseous.”
If multiple people who shared a meal, like at a barbecue or restaurant, become sick within a few hours, food poisoning is the more probable culprit. Food poisoning arises from improperly prepared, refrigerated, or washed food, leading to contamination by bacteria, viruses, or parasites. If the meal was consumed a day or two prior, a stomach bug is more likely. Stomach bugs, also known as viral gastroenteritis, are typically caused by viruses such as norovirus and rotavirus. It’s important to note that a stomach bug is distinct from influenza, which is a respiratory infection.
The duration of illness also differs between food poisoning or stomach bug. “Food poisoning is generally short-lived, resolving within 24 to 48 hours at most,” Dr. Jackson notes. “While you might feel lingering fatigue, the diarrhea and vomiting should subside. Stomach bugs, however, usually take three to five days for full recovery.”
Treatment for Food Poisoning and Stomach Bug
Despite the differences in cause and duration between food poisoning or stomach bug, the primary treatment approach is largely the same: rest and hydration. Drinking plenty of water and electrolyte-rich beverages is crucial to replace fluids lost through vomiting and diarrhea.
“For young children, encourage hydration in any appealing form,” Dr. Jackson advises. “Popsicles, Jell-O, ice chips, or slushies can be effective and enjoyable ways to get fluids into a sick child.”
If vomiting is frequent, stick to clear fluids like broth until it subsides. If diarrhea is the main symptom, you can gradually introduce foods that help solidify stool. Dr. Jackson recommends starting with the BRAT diet—bananas, rice, applesauce, and toast—and then expanding to other easily digestible foods.
It’s generally advisable to avoid anti-diarrheal medications unless specifically recommended by a healthcare professional.
“Diarrhea is a natural bodily response to eliminate bacteria or viruses,” Dr. Jackson explains. “Using anti-diarrheal medications can hinder this process.”
To prevent the spread of a stomach bug within a household, especially if one family member is sick, disinfect frequently touched surfaces like doorknobs, counters, and remote controls. Frequent handwashing is also essential. Avoid sharing food, drinks, and utensils with anyone who is ill.
When to Seek Medical Attention for Suspected Food Poisoning or Stomach Bug
Most healthy adults and older children can manage food poisoning or stomach bug at home, provided they can stay hydrated. However, dehydration is a serious concern. Watch for signs like decreased urination, dark urine, excessive thirst, and dizziness. If these symptoms appear, it’s important to consult a doctor or visit an urgent care center.
Dr. Jackson emphasizes that age is a significant factor regarding dehydration risk. “Infants and young children under 5, as well as older adults over 65, are at higher risk of complications from dehydration,” she states. “Especially if they have pre-existing chronic conditions, medical evaluation at urgent care is recommended if they show signs of dehydration.”
Seek medical help if symptoms persist beyond five days, or if you experience any of the following: a high or persistent fever, severe abdominal pain unrelated to vomiting or diarrhea, or blood in your stool. These symptoms could indicate a more serious condition than just food poisoning or stomach bug.
Preventing Food Poisoning and Stomach Bug Infections
After experiencing food poisoning or stomach bug, most people are motivated to prevent future occurrences. “Preventing stomach bugs is similar to preventing colds or flu,” Dr. Jackson says. “Practice diligent handwashing and try to avoid close contact with people who are visibly ill.”
To prevent food poisoning, proper food handling is key. Thoroughly wash fruits and vegetables. Exercise caution when handling raw meat; use separate utensils and cutting boards for meat and produce. Ensure meats are cooked to an internal temperature of 165 degrees Fahrenheit. Refrigerate leftovers promptly after meals.
