How to Travel with IBS Without Letting Your Gut Ruin Your Holiday
If you're travelling with IBS this summer, you're probably wondering how to avoid bloating, diarrhoea or constipation while you're away. Whether you're flying abroad or taking a UK staycation, travelling with IBS can feel overwhelming..
Summer holidays should be about relaxing, exploring new places and making memories-not worrying about where the nearest toilet is.
Yet if you're travelling with IBS or digestive issues, holidays can feel more stressful than enjoyable. You may find yourself wondering whether the hotel breakfast will upset your stomach, if you'll make it through a flight without bloating, or whether you'll spend your holiday planning every day around your bowels.
If this sounds familiar, you're certainly not alone.
Many of the women I work with tell me they dread travelling because of their IBS. The unpredictability of symptoms often means they avoid eating out, cancel excursions or spend the whole holiday feeling anxious rather than present.
The good news is that IBS doesn't have to dictate your holiday. With a little preparation and a few practical strategies, you can travel with far more confidence and enjoy your summer without your gut dictating everything.
Why Does IBS Get Worse When You Travel?
Many people assume it's simply the holiday food that causes digestive symptoms, but it's usually much more than that.
Travelling often disrupts the daily habits that help keep your digestive system working well.
These include:
Eating at different times
Skipping meals before travelling
Long flights or car journeys
Dehydration
Hot weather
Poor sleep
Alcohol
Richer foods
Increased stress and travel anxiety
I often explain this using a bucket analogy.
Each of these factors adds a little more to the bucket. One on its own may not cause symptoms, but when several happen together, the bucket overflows-leading to bloating, abdominal pain, diarrhoea or constipation.
That's why looking after your gut while travelling isn't just about avoiding certain foods. It's about supporting your digestive system as a whole.
12 Practical Tips for Travelling with IBS
1. Don't Skip Meals Before Travelling
Many people avoid eating before a flight because they're worried about needing the toilet.
Ironically, this can sometimes make symptoms worse.
Regular meals help support healthy digestion and can reduce the likelihood of overeating later in the day.
2. Stay Well Hydrated
Hot weather, air travel and spending long days sightseeing all increase your fluid requirements.
If you're prone to constipation, dehydration can make symptoms worse.
Carry a reusable water bottle and sip regularly throughout the day.
On the aircraft humidity is maintained at 10–20% by removing moisture from the cabin air combined with lower air pressure. Both of these can cause an increased water loss, by loss of water through the skin and through breathing (1). So although we are not doing much sitting on the plane we are requiring more fluids.
3. Keep Moving
Long periods of sitting can slow the digestive system.
Whether you're travelling by plane, train or car, try to stand up regularly, stretch your legs and walk around whenever possible. Try walking around the airport before your flight, rather than sitting and waiting for it.
Even a short walk after meals can help support normal digestion.
4. Pack Familiar Snacks
Having foods you know your gut tolerates well reduces stress if suitable options aren't available. I always have some snacks in my hand luggage, just in case.
Ideas include:
Oatcakes
Rice cakes
Bananas
Nuts (if tolerated)
Low FODMAP snack bars if you already use them
5. Don't Experiment with New Foods Every Meal
Trying local food is part of the holiday experience.
Instead of avoiding everything unfamiliar, balance new foods with meals you already know your digestive system handles well.
From my experience, often travelling to Mediterranean countries the food is less processed and simpler cooking methods mean foods can be better tolerated. Opt for fresh fish or meat, roasted vegetables, or simple salads.
6. Eat Slowly
Holiday meals are often longer and more relaxed.
Take advantage of this.
Eating more slowly and chewing thoroughly can help reduce swallowed air and may improve digestive comfort.
7. Manage Travel Stress
The gut and brain are closely connected.
Airport queues, delayed flights, navigating unfamiliar places and worrying about symptoms can all influence how your gut behaves.
Simple breathing exercises, listening to music or allowing extra time before travelling can all help lower stress levels.
8. Be Sensible with Alcohol
A cocktail by the pool doesn't have to be off-limits.
The key is moderation.
Alternate alcoholic drinks with water and be mindful of how different drinks affect your own symptoms. Go easy on the cocktails and fizzy alcoholic drinks.
9. Keep a Similar Routine
Your digestive system likes routine.
Where possible, try to eat meals at roughly the same times each day and maintain your usual sleep schedule.
10. Prepare for Flying with IBS
Flying itself doesn't cause IBS, but dehydration, prolonged sitting and altered meal times can contribute to symptoms. Cabin pressure causes gases inside the bowel to expand, meaning many people experience increased bloating during flights-even if they don't normally have IBS
Choose an aisle seat if it helps you feel more relaxed and allows easy access to the toilet.
11. What to Avoid
Some things may not be helpful before or during a flight, such as fizzy drinks (hello more gas), chewing gum, spicy foods, caffeine, alcohol and large meals.
12. Remember That IBS Management Isn't Just About Food
One of the biggest misconceptions about IBS is that it's all about what you eat.
Food matters, but so do stress, sleep, movement, hydration and the gut-brain connection.
Looking at the bigger picture often leads to better long-term symptom management.
What Should You Eat Before a Flight if You Have IBS?
There isn't one perfect pre-flight meal for everyone with IBS. The best approach is to choose foods that you already know your gut tolerates well. Holidays are rarely the best time to experiment with unfamiliar foods or make major changes to the way you eat.
From my own experience of travelling with a sensitive gut, I've found that keeping things simple works best.
If I'm catching an early morning flight, my go-to breakfasts are usually porridge, overnight oats, chia pudding or eggs (often without the bread). These are meals I know suit me and leave me feeling comfortable while travelling.
For flights later in the day, I'll often choose something light and familiar, such as a sushi pack, a handful of nuts (if I'm tolerating them well), or a snack pot containing eggs and smoked salmon.
When eating on the plane, I tend to keep things fairly simple too. If the airline meal contains foods that I know are more likely to trigger my symptoms, I may just eat the protein and bring some of my own snacks. If travelling long-haul, some airlines allow you to choose a bland meal, which is generally chicken/fish and potato with no elaborate sauces. On my last few long-haul flights, I've found these approaches have worked well for me and I've managed to avoid the bloating I used to experience.
I also skip fizzy drinks while flying, as they can increase the amount of gas in the digestive tract and make bloating feel worse. Instead, I focus on drinking plenty of water throughout the flight to help stay hydrated.
Your IBS Holiday Packing Checklist
Having a few essentials with you can make travelling feel much less stressful.
✔ Any over-the-counter remedies you've used successfully before
✔ Reusable water bottle
✔ Familiar snacks
✔ Rehydration sachets (particularly if you're prone to diarrhoea)
✔ Hand sanitiser
✔ Spare underwear if it helps you feel more confident
✔ Prescription medication if you usually use it
Sometimes simply knowing you've prepared for the unexpected can reduce travel anxiety.
Frequently Asked Questions About Travelling with IBS
Can flying make IBS worse?
Flying doesn't directly cause IBS symptoms, but dehydration, long periods of sitting, changes in meal timing and travel-related stress can all contribute to digestive discomfort.
As the plane goes up the pressure in the cabin drops. That change in pressure can cause the gas in your abdomen to expand, a bit like blowing up a balloon. Therefore, abdominal distention can increase. Therefore, wearing something comfy to travel in with an expandable waist can be more comfortable.
Travel can often delay our bowel movements due to the disruption of our meal timings, crossing time zones and lower fluid intake (2).
Should I avoid eating before a flight?
Generally, no. Skipping meals may make symptoms worse for some people. Eating regular meals often supports more comfortable digestion than fasting before travelling. I would not eat a large meal before a flight so I would recommend keeping it light.
Can stress make IBS worse while travelling?
Yes. The gut and brain communicate constantly, which means travel anxiety can influence digestive symptoms. Planning ahead and using simple relaxation techniques may help you feel more comfortable.
Travel data identified vulnerability to diarrhea under stress, illness anxiety, and pre-travel adverse life events as predictors of post-travel IBS, and flare ups (3).
