Dr Donald Grant says you could end up with ‘jet belly’ unless you avoid a list of foods and stick to something safer
A doctor has warned anyone heading to the airport to avoid foods that could cause a painful reaction, including cabbage, cheese and beans. Dr Donald Grant says foods like dairy can cause a reaction known as ‘jet belly’, where your stomach reacts in the same way as an unopened crisp packet.
Aeroplane bloat, also known as ‘jet belly’, is a phenomenon that causes the stomach to bloat during flights. Dr Grant, GP and Senior Clinical Advisor at The Independent Pharmacy, said: “Many people will be planning or preparing to go on holiday. On long-haul flights, it’s important to be aware of ‘aeroplane bloat’, categorised as a build-up of gas in the intestines and stomach, caused by a combination of factors.
“This strange phenomenon is influenced by cabin pressure. At 30,000 feet, plane pressure drops dramatically, causing the gas in our guts to expand. In turn, this causes bloating and discomfort, which can lead to aeroplane bloat. It’s kind of like how crisp packets expand while in the air – the same effect is happening to our guts.
“Additionally, sitting in the same place for hours during a long-haul flight doesn’t help either. This fixed position can slow digestion and increase gas buildup, further adding to the discomfort and bloating. Depending on an individual’s food tolerances, purchasing and eating food on a plane could also increase the bloating effect, especially if the foods are high in salt content.
How to Avoid Aeroplane Bloat this Summer
“So, now that people are aware of aeroplane bloat, how can they avoid it? With the right approach, such as remaining hydrated and choosing foods carefully, people can enjoy their long-haul flights without the risk of bloating or discomfort.
1. Hydration is Key
“When we’re dehydrated, digestion is slowed and the risk of bloating increases. Therefore, drinking substantial amounts of water can make a huge difference, limiting the risk of this bloating effect. Additionally, I advise against fizzy drinks as the carbonation can increase gas buildup. Realistically, adults should be aiming for 2-2.5 litres of fluid each day, but prioritise still water before a flight.
2. Opt for Light Meals Pre-Flight
“Aside from drinking water, what we eat also plays a massive role in the risk of experiencing aeroplane bloat. Stay away from salty foods and anything hard to digest, including beans, cabbage, dairy products or fatty foods. Instead, lighter foods such as rice and lean proteins such as poultry or fish are generally better options as they’re easier to digest and manage.
3. Try and Move Each Hour
“While it can be tricky to incorporate movement into your flight, a walk to the toilet and back every hour or two can reduce the risk of aeroplane bloat. By moving, we’re aiding our digestive system, allowing it to work more efficiently. This actively reduces the risk of bloating.
4. Consider Probiotics or Over-the-Counter Medication
“For people with a long history of gut health issues, probiotics or other over-the-counter treatments can prove incredibly effective at targeting and reducing bloating or discomfort. Medications such as FyboCalm Wind & Bloating Relief are available without a prescription, providing relief of bloating, wind and abdominal pain in as little as two hours.
“Overall, with the holiday season underway, it’s important to be aware of aeroplane bloat and the factors that can increase the risks. However, by drinking enough still water, avoiding any trigger foods and packing emergency over-the-counter medication, I believe people can dramatically reduce the risk of experiencing this strange phenomenon.”
