Understanding Stomach Bugs (Viral Gastroenteritis)
A stomach bug is an infection of the stomach and intestines—most often caused by viruses like norovirus or rotavirus. It’s common and usually mild, but dehydration is the main concern, especially for young children, older adults, and anyone with weakened immunity.
What Is a Stomach Bug?
Viral gastroenteritis irritates the stomach and intestines, leading to sudden nausea, vomiting, and diarrhea. Most people start to improve within 1–3 days; full recovery can take up to a week.
Common Symptoms
- Nausea and vomiting
- Diarrhea (sometimes watery)
- Abdominal cramps or pain
- Low-grade fever or chills
- Headache, muscle aches, or fatigue
- Loss of appetite
Seek medical care right away if you notice signs of dehydration (dizziness, dry mouth, dark or infrequent urination), high fever (over 102°F / 38.9°C), blood in stool or vomit, severe abdominal pain, or symptoms lasting longer than 3 days.
What Causes Stomach Bugs?
Most cases are viral and spread easily through contaminated food, water, or surfaces—or by close contact with someone who’s infected. You can catch it by:
- Eating or drinking something contaminated
- Touching a contaminated surface, then your mouth
- Sharing utensils, food, or drinks
- Being in close contact with someone who is sick
How Is It Treated?
Most stomach bugs resolve on their own. The priority is replacing fluids and electrolytes lost from vomiting or diarrhea.
- Sip water or oral rehydration fluids often (small, frequent sips)
- Try clear broths, herbal teas, or electrolyte drinks
- When ready, start bland foods (bananas, rice, applesauce, toast)
- Avoid dairy, caffeine, alcohol, and greasy or spicy foods until fully recovered
- Rest to support immune recovery
Antibiotics don’t help viral infections and may worsen symptoms. Your provider may recommend medication for nausea or severe diarrhea if needed.
How to Prevent Stomach Bugs
- Wash hands often—especially before eating or preparing food
- Avoid sharing utensils, food, or drinks
- Disinfect frequently touched surfaces (doorknobs, counters, phones)
- Store and cook food safely to prevent bacterial contamination
- Stay home if you’re sick to protect others
