Before You Leave

Pack Your IBS Travel Kit

• Digestive enzymes — Take with EVERY restaurant meal. Your most important travel item. Pack in carry-on.
• Regularity Companion — Travel constipation prevention. Start 2 days before departure.
• Probiotics — Maintain your microbiome through travel disruption.
• Protein powder — Single-serve portions. Emergency nutrition when safe food is unavailable.
• Imodium (loperamide) — For IBS-D emergencies
• Peppermint oil capsules — For acute cramping
• Safe snacks — Nuts, rice cakes, protein bars you have vetted

Research Your Destination

• Find restaurants with customizable menus (avoid set menus)
• Locate grocery stores near your hotel for safe food backup
• Book accommodations with a kitchenette if possible — the ability to cook even simple meals is transformative
• Learn key phrases in the local language: "no garlic," "no onion," "plain grilled"

On the Plane

• Gas expansion: At cruising altitude, cabin pressure causes intestinal gas to expand 25-30%. Eat lightly before flying. Avoid carbonated beverages. Take digestive enzymes with your airport meal.
• Dehydration: Cabin humidity is 10-20% (desert level). Drink water aggressively — at least 8 oz per hour of flight. Dehydration worsens constipation and concentrates irritants in the gut.
• Movement: Walk the aisle every hour if possible. Sitting immobile for hours slows gut motility.
• Aisle seat: Book an aisle seat. Unrestricted bathroom access reduces anxiety, which reduces the stress-triggered gut response.
• Skip the airline food: Airline meals are unpredictable. Bring your own food or eat before boarding.

At Your Destination

Restaurant Strategy

1. Choose restaurants where you can see ingredients: grills, sushi, steakhouses, build-your-own concepts
2. Order simple: grilled protein + plain starch + steamed vegetable
3. Ask about garlic and onion specifically — servers understand these requests
4. "Sauce on the side" for everything
5. Take digestive enzymes before every restaurant meal

Maintaining Routine

• Eat meals at the same times as home (adjust for time zones gradually)
• Maintain your morning bathroom routine — even if it means waking 30 minutes early
• Continue exercise — even walking 30 minutes daily maintains gut motility
• Sleep 7-8 hours — sleep deprivation is a potent IBS trigger

International Travel Specific

• Water safety: Drink bottled water in developing countries. Use bottled water for brushing teeth too. Ice is risky.
• Traveler's diarrhea prevention: Probiotics (particularly Saccharomyces boulardii) started before travel reduce risk by 40-60% in clinical trials.
• Food safety: "Cook it, boil it, peel it, or forget it." Raw vegetables washed in local water are risky.
