Keeping your gut happy whether you're traveling locally or internationally
🌍 How Travel Affects Digestion
Travel can significantly disrupt your digestive system through changes in routine, diet, time zones, and exposure to new microorganisms.
Common Travel-Related GI Issues
- Traveler's diarrhea: Most common travel illness (30-70% of travelers to high-risk areas)
- Constipation: From dehydration, changes in routine, ignoring urges
- Bloating: Air travel, dietary changes, stress
- Heartburn: Irregular meals, unfamiliar foods, stress
- Jet lag effects: Disrupts gut's circadian rhythm
