For those suffering from IBS, dining out with friends and family can be tricky and sometimes stressful – especially when you are still unsure of your main triggers.
Alcohol consumption is a common trigger for nearly all those with IBS, causing pain, bloating, urgency and diarrhoea. Not so good when you just want to have a few drinks with your friends on a special occasion, right? We know, it’s not fair!
When it comes to foodstuffs, people’s IBS symptoms can vary from person to person. Some may have adverse effects on foods that other people can tolerate well and vice versa.
However, alcohol is a particularly common trigger.
So to help, we’ve pulled together some information about IBS and alcohol, including the best-tolerated alcohol for those with IBS…
…and what to avoid.
Alcohol itself is a gut irritant, so it may worsen IBS symptoms regardless of which type you choose. For those who suffer from IBS, alcohol commonly exacerbates symptoms.
Alcohol can also impact our gut microbiota (gut bacteria), so regularly drinking can lead to a disruption of our balance of good gut bacteria.
The type of alcoholic beverage will determine whether it is low or high FODMAP.
Some high FODMAP alcoholic beverages to avoid are:
Some low FODMAP alternatives include:
It is important to note that even if you choose a low FODMAP alcohol, it may still exacerbate symptoms due to alcohol itself being a gut irritant.
Carbonated beverages will naturally add gas and air into the digestive system by their very nature. This can cause gut spasms and distention (swelling of the abdomen).
So, if bloating and pain are common symptoms for you, try to avoid fizzy drinks altogether.
Examples include fizzy mixers, ciders and sparkling wine (tear!).
Fructose, which is the sugar found in fruit, is a simple sugar that is poorly digested by the body (i.e. a FODMAP). In 2008, a study found that almost one-third of IBS patients within the study were fructose intolerant.
As fructose passes through our gut, it is poorly digested and so passes mostly straight through to our colon, where it ferments.
This again, can lead to pain and bloating. One study has shown that following a lower fructose diet improves symptoms in some patients.
Artificial sweeteners, usually found in diet drinks contain polyols, which are FODMAPs that can trigger gastrointestinal distress. Try to avoid drinks containing artificial sweeteners ending in – 'ol' such as sorbitol, xylitol, mannitol and maltitol.
Check the ingredients list to make sure you are avoiding these drinks.
So, after that list you may be saying to yourself…well, what alcohol can I drink with IBS?
Wine is made from grapes, which is a well-tolerated fruit from a FODMAP diet perspective, usually 1-2 glasses is tolerable to most.
As a guide try to choose wines with less than 6g sugar/litre where possible as this would be classified as low in sugar. 12g/litre would be classified as high.
Spirits such as vodka, gin and whiskey are low in FODMAPs and are fine for those with IBS, in small quantities. Make sure to pick ‘unflavoured’ varieties as the others may have sweeteners.
Try mixing them with soda water & lime. Cranberry juice may be appropriate, as the only fruit juice that is low in FODMAPs. However, check the label on your shop-bought carton to make sure it does not contain high-fructose corn syrup or artificial sweeteners.
Although beer and prosecco are carbonated, they are actually low in FODMAPs. So, if you can tolerate drinks with gas then either of these two beverages should be fine. Usually one can of beer or one glass of prosecco is advised.
IBS is not about restricting what you can do or enjoy but it is about what is finding the best for you. It just may take some time to figure this out!
If you choose to drink alcohol, here are our top tips that may reduce gut upset:
Always be responsible when drinking alcohol and ensure to stay hydrated and eat prior to ensure to keep your symptoms at bay and get the best out of your day.
