Don’t put up with an unhappy gut

Our gut feeling might be that your digestive system will process whatever you throw down it.

But all too often our food choices result in bloating, wind, heartburn, indigestion, constipation and irritable bowels – symptoms that, figures suggest, are becoming more and more common.

BLOATED BRITAIN

A recent survey by the nutritionist Patrick Holford found two-thirds of Brits feel bloated after eating, four out of five don’t go to the toilet every day, and a quarter of women complain of irritable bowel syndrome (IBS).

The results are supported by a 2015 Swansea University report, which found there have been increases in most gastrointestinal disorders across Europe, plus the latest national Diet and Nutrition Survey, which found the population is still consuming too much saturated fat, added sugars and salt, and not enough fruit, vegetables, oily fish and fibre.

DIGESTION ACTION

Holford, whose new book Improve Your Digestion has just been published, believes most digestive problems are easily resolved.

In the book, he suggests different measures for different complaints, such as reducing gut inflammation, which causes symptoms including indigestion, fatigue and headaches, by eating foods with a low glycaemic index (GI), which are antioxidant-rich but contain low levels of sugar, caffeine and alcohol, plus increasing the consumption of anti-inflammatory foods such as oily fish, red onions, turmeric, olives and ginger.

For inflammatory bowel diseases (IBD), including Crohn’s disease and ulcerative colitis, his recommendations include identifying foods that you’re allergic to, or intolerant of, and eliminating them, along with eating anti-inflammatory foods and following a low GI diet, and consuming rich sources of beta-glucans, from shitake mushrooms, oats or supplements.

While IBS – which the IBS Network estimates affects around 9million people in the UK – isn’t considered an IBD, advice around managing the condition is similar.

GET TESTED

The most common kind of immune reaction against foods isn’t food allergy but food intolerance, which leads to the production of IgG antibodies, explains Holford.

A common cause of bloating, he says, is eating food you’re unknowingly intolerant to.

It’s estimated one in five people are intolerant to gluten (which is not the same as having coeliac disease, an incurable autoimmune condition which causes the body’s immune system to attack healthy cells when even the smallest amount of gluten is consumed), so avoiding wheat is appropriate for them. Dairy is another common food which some people are intolerant to.

If someone follows healthy eating messages – eating plenty of fruit and veg and oily fish, keeping an eye on red meat consumption, and eating little processed food and saturated fats – they’re much less likely to suffer digestive health issues.

“However, some people do have hidden food intolerances and may suffer symptoms like bloating and IBS, despite an apparently good diet,” warns Holford. Indeed, lots of people with IBS can be sensitive to Fodmaps, found in numerous fruit and vegetables.

AGE MATTERS

He explains that in older people, stomach acid production, which is needed to help absorb nutrients, goes down, and two in five people over 60 have insufficient vitamin B12 in the blood due to poor absorption.

“This leads to accelerated brain shrinkage and a greater risk of dementia,” he says.

“A lack of stomach acid can also lead to bloating and indigestion.”

To maximise absorption, don’t drink tea or coffee with food, as substances in them can reduce absorption. Alcohol can also irritate the digestive tract and interfere with the amount of nutrients taken in.

FEEL FOR FIBRE

Healthy digestion depends on healthy elimination, says Holford, and people should go to the toilet twice a day.

“Contrary to popular belief, eating lots of fibre such as bran doesn’t make much difference. However, increasing soluble fibres, which are the kind found in oats and also chia seeds, does.”

Oats are both gluten-free and high in soluble fibres, which absorb water and are good for digestive health and regular bowel movements.

Holford also recommends people drink the equivalent of six glasses of water a day – which could be in tea or other hot drinks – to aid digestion and help “move things along”.

DOCTOR’S VIEW

Gastroenterologist Professor Julian Walters is co-author of What’s Up With Your Gut, which emphasises the importance of what people eat and their food intolerances, and the impact of poor digestion on overall health.

Walters says people are often told they have IBS, which currently has no specific treatment, when in fact they may have other conditions, for which they could be tested and possibly even cured.

“I see an endless stream of patients told they had IBS or chronic constipation, for instance, often suffering years of misery with their symptoms, but simple tests could pinpoint the real cause,” he says.

Gut symptoms account for one in five of all GP consultations in the UK, yet studies show 41% of people still don’t bother to see a doctor about their digestion problems.

Some symptoms shouldn’t ever be ignored and warrant a speedy doctor’s consultation, including blood in your stools, anaemia (looking pale and feeling tired), unexplained weight loss or a change in bowel habits, as these could be an indication of bowel cancer. And while most of the time digestive symptoms won’t be due to anything serious, it’s worth talking to an expert who can advise on how to best manage them.

“Gut complaints appear to be increasingly reported,” says Walters.

“And people shouldn’t have to suffer in silence, their lives extremely restricted in some cases by their symptoms, when good treatments and cures for everyday symptoms exist.

“Also, sometimes putting off seeking advice for embarrassing symptoms can delay a cancer diagnosis and cost lives.”
