Traveling is a thrilling experience, but it often comes with an unwelcome companion: jet belly—a term coined for the bloating, gas, and digestive discomfort caused by shifts in cabin pressure, disrupted routines, and exposure to new microbes. Recent studies reveal that air travel alters gut microbiota diversity within hours, increasing risks of constipation, diarrhoea, and fatigue. In this blog, we dive into the science of jet belly, explore its impact on gut health, and share evidence-based strategies to protect your microbiome, featuring Dulwich Health’s OxyTech and Bio-Culture as essential tools for travellers.
Trending News: The Gut Microbiome’s Vulnerability to Travel
A 2025 study in Gut Microbes found that air travel disrupts the gut’s microbial balance by altering oxygen levels and reducing beneficial bacteria like Bifidobacterium. Researchers observed that travellers with less resilient microbiomes experienced prolonged digestive issues post-flight, while those who prepared their guts with probiotics and oxygen-based supplements recovered faster. These findings align with the growing focus on microbiome resilience as a cornerstone of travel wellness.
What Causes Jet Belly?
Jet belly stems from three key factors:
1. Cabin Pressure Changes: Fluctuating air pressure during flights slows digestion and promotes gas buildup.
2. Microbiome Disruption: Exposure to new pathogens and dietary shifts reduce microbial diversity.
3. Dehydration: Dry cabin air and limited water intake impair gut motility and nutrient absorption.
Science-Backed Strategies to Combat Jet Belly
1. Pre-Travel Gut Preparation
- Boost Fibre Intake: A high-fibre diet (think oats, apples, lentils) feeds beneficial gut bacteria. Pair with OxyTech capsules to gently cleanse the colon and enhance nutrient absorption before departure.
- Probiotic Supplementation: Dulwich Health’s Bio-Culture capsules introduce Lactobacillus and Bifidobacterium strains to fortify gut flora against disruptions.
2. In-Flight Protection
- Hydrate Strategically: Sip electrolyte-enhanced water hourly to counteract dehydration. Avoid carbonated drinks, which worsen bloating.
- Use OxyTech Capsules: Take 1–2 capsules mid-flight to release oxygen into the gut, breaking down gas and supporting aerobic bacteria].
- Avoid Gut Disruptors: Skip alcohol, caffeine, and processed snacks. Opt for pre-packed gut-friendly snacks like nuts, seeds, or dried fruit.
3. Post-Travel Recovery
- Rebuild with Probiotics: Resume Bio-Culture capsules for 7–10 days to restore microbial diversity after exposure to unfamiliar bacteria.
- Gentle Detox: Use OxyTech nightly to cleanse the colon of toxins accumulated during travel.
