Flu or stomach bug? They’re not the same—and this season is trickier than usual.
Dr. Gloria Guptill of Delmar Internal Medicine breaks it down:
🫁 The flu = primarily a respiratory illness
Think sudden high fever, body aches, cough, sore throat, congestion, headache, fatigue, and chills.➡️ Sometimes nausea, vomiting, or diarrhea can tag along—but they’re not the main event.
🤢 The stomach bug = digestive system takeover
Vomiting, watery diarrhea, stomach cramps, mild fever, and dehydration symptoms like dry mouth.
➡️ No cough or sore throat? That’s a clue.
The biggest giveaway?
• Lungs + throat hit hard → think flu (confirm with an at-home flu test)
• Gut symptoms front and center → likely stomach bug
What to do:
Both spread easily, so rest, hydrate, and stay home.
• Flu: fever/pain relievers, decongestants, cough meds—and ask your doctor about antivirals
• Stomach bug: fluids first, bland foods, patience (unfortunately)
🚨 Always call a doctor if symptoms worsen or if you’re high-risk (older adults, young kids, pregnant, or immunocompromised).
Bottom line: listen to your body—and don’t play guessing games when symptoms escalate.
