Because you want to see more than just the inside of a toilet while you're away. Dr Hazel Wallace explains how to prep for your trip, stay free of the runs while you're there - and if the worst strikes, how to get better fast

There is nothing more inconvenient than catching a tummy bug while on holiday or travelling. My worst experience of this was as a 20-year-old volunteering in a hospital in New Delhi. I was living with a family in the slums and essentially lived, and ate, how they did. I felt very proud of myself for immersing myself deeply in their culture, until the third day when I was struck down pretty badly with ‘Delhi belly’. This was made worse by the fact that it was during their hottest and most humid season, not to mention the fact that I didn't have access to an actual toilet.

At one point I considered admitting myself to the hospital I was working at and hooking myself up to a drip, but through rest and adequate hydration with water and rehydration salts, I was over the worst of it after two or three days. But it certainly changed my attitude when it comes to travel and now I won’t fly anywhere without a couple of packs of Dioralyte in my bag just in case.

My case is not unique and it is estimated that traveller’s diarrhoea can affect up to 50 per cent of travellers. It is usually caused by eating food, or drinking water, contaminated by bugs such as bacteria, viruses and parasites, or it can be spread from person to person. In addition to diarrhoea, symptoms include fever, vomiting and tummy pain. In most cases, it causes a mild illness and symptoms clear within three or four days.

However, there are a few things that you can do in the run-up to your trip and while you’re away to prevent the dreaded holiday belly ruining your trip.

Before you go away

Take probiotics

There are probiotics containing certain strains of bacteria (Saccharomyces Boulardii and a mixture of Lactobacillus Acidophilus and Bifidobacterium Bifidum) that appear to be effective in preventing traveller's diarrhoea. It is not something doctors routinely prescribe but it they are generally safe and appear to be effective. If you don’t want to take a supplement you can stock up on probiotic-rich foods such as kefir (fermented milk drink), kombucha (fermented sweet tea), kimchi (fermented Chinese cabbage), sourdough bread and yoghurts which contain active, live cultures. Probiotic foods I would have in your diet regardless if you are travelling or not, if you do wish to take a probiotic supplement it is recommended to start on the day of travel and stop on the day of return.

Eat prebiotic food

Prebiotics are a source of food for probiotics to grow, multiply, survive and thrive in the gut. They essentially act as the fertiliser for our gut garden of microbes. Prebiotics are soluble fibres, which are found in foods such as artichokes, onion, garlic, chicory, asparagus and leeks. However, one big thing to note is that these fibre-rich foods can make you bloat and a little gassy which may be made worse when you fly. This is all down to physics because as the atmospheric pressure drops in the cabin, the air inside our gut expands to fill the space. To avoid feeling uncomfortable, and saving other passengers from potentially smelly farts, you can load up on these foods in the weeks before you travel but cut them down, or out, 24 hours before you fly so that you have time to digest them fully - but don’t forget to reintroduce once you land!

Emergency pack

Just in case you do get ill when you’re away, pack some anti-diarrhoeal tablets such as loperamide (aka Imodium) and rehydration salts such as Dioralyte in your wash bag or first aid kit. It can also be quite useful to carry a thermometer also - especially if you are travelling with kids.

While you’re away

I don’t want you to worry about getting sick while you’re abroad and I fully encourage that you immerse yourself in the culture and try new things - including the local food. However, there are a few things to keep in mind to try to ensure you stay well on your trip.

Wash/sanitize your hands

Sounds really obvious but it is the simplest, most effective way of preventing the spread of bugs to you or to other people. If you can’t get access to water, carry a little bottle of hand sanitizer.

Drink bottled water or cooled boiled water

When you can’t be sure of the purity of the local water, then it should go without saying that you should avoid the local tap water - including ice in your drinks. Even if locals drink it without any problems, your stomach may not have the right bacteria to protect you from becoming ill. If you want to reduce the number of bottles you buy, you can also try boiling the water and drinking it cool. This is the most reliable method of removing bugs, but will not remove dirt.

Recommended vaccines

There are no vaccines that prevent traveller’s diarrhoea as a whole. However, there are some other vaccines that you may need for your travel, such as hepatitis A, typhoid, etc to avoid getting ill. You may also need to take malaria tablets depending on where you are travelling. Speak to your GP eight weeks before you travel and check out the NHS Fit for Travel website.

Avoid raw or undercooked food

Freshly prepared, well-cooked food, served hot, is generally safe but as a rule of thumb try to avoid uncooked meat, fish or eggs, and consider swapping your salads, which may have been washed in unclean or contaminated water for cooked vegetables instead.

Be careful at the buffet

Buffets can also be a bit of a danger zone as, unless you can ensure the food is fresh, it might have been lying around for a couple of hours. Many people avoid street vendors because they worry about contamination or the quality of the food, however more often than not they cook it fresh in front of you and have a high turnover of food so it may actually be better than buffet restaurants.

What to do if you do get sick

In most cases, traveller's diarrhoea does not need any specific medical treatment. The most important thing is to make sure that you drink plenty of fluids to avoid lack of fluid in your body. As a rough guide, drink at least 200mls after each bout of diarrhoea (note: this extra fluid is in addition to what you would normally drink!). If you are struggling to keep water down at all and suspect that you are becoming dehydrated, you should seek medical advice.

There is no best food to eat if you get sick, but avoid anything spicy, fried or fatty food and also alcohol as it may make it worse.

Rehydration salts such as Dioralyte are also very useful and are easy to carry with you. They are sold in sachets and contents are simply added to water. They won’t stop or reduce diarrhoea. However, the small amount of sugar and salt helps the water to be absorbed better from the gut into the body.

You can also take an antidiarrheal medicine (e.g. loperamide) as mentioned earlier. If you forget to pack them you should be able to get them in a pharmacy where you are travelling.

When you return

Despite all these measures, if you still caught a bug while travelling the best thing you can do when you get home is to try to support your healthy gut bacteria through a good diet - lots of fibre and probiotic-rich foods. You may also wish to try a probiotic supplement for a couple of weeks.
