Everything You Need to Know About Stomach Bugs: Symptoms, Treatment, and Recovery
A stomach bug hits hard and fast. This common illness affects millions of people each year. The medical term for it is viral gastroenteritis. The infection causes inflammation in your stomach and intestines.
What Causes a Stomach Bug?
Several viruses trigger stomach bugs:
Norovirus stands out as the leading cause. It spreads quickly in crowded places like schools, cruise ships, and nursing homes. Rotavirus primarily affects young children. Adenovirus and astrovirus round out the common viral culprits.
Symptoms to Watch For
The signs of a stomach bug appear within 12-48 hours after exposure. Here’s what happens in your body:
| Symptom | Duration | Severity |
|---|---|---|
| Nausea | 1-3 days | Moderate to severe |
| Vomiting | 1-2 days | Intense at first, then tapering |
| Diarrhea | 2-5 days | Frequent, watery |
| Stomach cramps | 2-3 days | Sharp, intermittent |
| Low fever | 1-2 days | Usually under 100.4°F |
| Body aches | 2-3 days | Mild to moderate |
How It Spreads
Stomach bugs move from person to person through:
- Direct contact with someone who’s sick
- Touching contaminated surfaces
- Eating contaminated food
- Drinking contaminated water
The virus stays active on surfaces for days. Someone with the infection remains contagious for at least three days after symptoms stop.
Treatment Steps That Work
Your body fights off the virus on its own. These steps speed up recovery:
- Rest completely for the first 24 hours
- Drink clear fluids in small sips
- Start with ice chips if you’re struggling to keep liquids down
- Add bland foods slowly as you feel better
- Take electrolyte solutions to replace lost fluids
The Recovery Timeline
Most people bounce back within 1-3 days. Here’s what to expect:
Day 1: Symptoms hit hard. Focus on hydration.
Day 2: Symptoms start improving. Try small amounts of food.
Day 3: Energy returns. Diet begins normalizing.
Day 4-5: Full recovery for most people.
Prevention Strategies
These habits stop stomach bugs from spreading:
- Wash hands thoroughly with soap for 20 seconds
- Clean and disinfect surfaces regularly
- Avoid preparing food while sick
- Stay home until 48 hours after symptoms end
- Wash contaminated items with hot water

Long-term Effects

The Bottom Line
