For greater than 17 years, James Lavers was assured by a number of docs that the bloating and ache he skilled on and off from his early 20s was irritable bowel syndrome (IBS). His story is way from distinctive.
Intestine complaints are extraordinarily widespread, accounting for one in 5 GP consultations and hundreds of thousands of over-the counter gross sales of gastric aid merchandise, for all the pieces from acid reflux disease and bloating to diarrhoea. And IBS, thought to have an effect on as much as 14 million individuals within the UK, is a quite common analysis.
But some consultants imagine that docs are too able to counsel that is the reason for sufferers’ signs. They argue that there are different situations, some beforehand dismissed as ‘hokum’ (see field under), that would lie on the root of the issue — and, satirically, the very remedy sufferers are given to ease their intestine signs might make these worse.
Plainly this was the case for James, 36, a property administration marketing consultant. From his early 20s, he suffered from episodes of bloating and painful cramps each few weeks. As soon as, in 2003, he went to A&E as a result of the ache was so unhealthy, however docs stated it was trapped wind.

‘Over time I should have seen 4 completely different GPs and as many gastroenterologists, on the NHS and privately, and so they all appeared to agree it was IBS,’ says James, who lives in South London along with his spouse Sally, 34, an accountant, and eight-month-old daughter Esme. However the therapies, akin to antispasmodic medication for wind and bloating, made no distinction.
‘The signs actually impacted my on a regular basis life, affecting my social life and wellbeing,’ he says. ‘If I had an evening out consuming and ingesting, I might endure for days afterwards.’
James paid to see nutritionists — 5 in 15 years — who suggested him variously to take probiotics, digestive enzymes, vitamin and mineral dietary supplements.
‘Typically they did blood exams or stool exams and stated I had deficiencies,’ says James. ‘These dietary supplements might price as much as £300 for a few months’ provide, however I used to be by no means completely satisfied about them.

‘I used to be additionally informed I might need meals intolerances, so at numerous factors I attempted excluding wheat/gluten and dairy, after which FODMAPs.’ (These are sugars present in meals akin to onions, garlic and a few fruits that ferment within the small gut and have been proven to trigger bloating and diarrhoea in some individuals.)
Compounding the issue, in his mid-20s James additionally started affected by belching, heartburn and acid reflux disease that left his throat ‘sore and uncooked’.
‘It was ruining my life — I might generally really feel so sick I could not eat for days,’ he says. He noticed a gastroenterologist privately, and after a gastroscopy (the place a digital camera is handed down the throat in a skinny, slim tube) he was identified with acid reflux disease and prescribed proton-pump inhibitor (PPI) medication to suppress his abdomen acid manufacturing.
Whereas the acid reflux disease signs improved, he was nonetheless dwelling with the bloating, cramps and belching, with ‘a very unhealthy assault’ each six months or so for the following decade. Then, 18 months in the past, he went to a non-public clinic specialising in intestine complaints on the advice of a buddy.
The marketing consultant ran plenty of exams, together with a easy breath take a look at for small intestinal bacterial overgrowth (SIBO).
This situation happens when there’s an excessive amount of micro organism within the small gut which ferment, producing gases akin to hydrogen and methane and inflicting signs within the higher finish of the digestive tract, together with belching and bloating, in addition to heartburn-type signs or a sense of a lump within the throat.
If the micro organism overgrow within the decrease finish of the small gut, this may trigger decrease bowel signs, akin to cramps, bloating, adjustments in bowel behavior, diarrhoea and free stools. In different phrases, signs much like these of IBS.
Analysis means that as much as two-thirds of IBS circumstances could also be attributable to this micro organism overgrowth. A examine printed on-line within the medical journal Surgical Endoscopy discovered that two-thirds of 104 sufferers referred with regurgitation signs (i.e. acid and reflux) that had proved immune to remedy, additionally had SIBO.
Though the situation was first recognized greater than 50 years in the past, it has been regarded with scepticism by some gastroenterologists. However that has lately modified — as an example, the British Society of Gastroenterology’s pointers on the administration of persistent diarrhoea, printed in 2019, advocate SIBO needs to be ‘routinely thought of as a attainable explanation for GI [gastrointestinal] signs’.
Regardless that it is extensively accepted now that some sufferers with IBS might have SIBO, consciousness of the situation typically continues to be poor amongst GPs and a few gastroenterologists, so individuals are not often checked for it, says Nick Boyle, a reflux surgeon primarily based in Tunbridge Wells, who led the most recent analysis.
Because of this, sufferers can have signs for years and be informed they’ve IBS or reflux and that they need to stay with it, when really they’ve SIBO, which is treatable and curable, says Mr Boyle. This contrasts with IBS, for which there isn’t any treatment — though antispasmodics, laxatives and different therapies will help handle signs.
Probably the most widespread causes of the issue, suggests Mr Boyle, are PPI medication prescribed to deal with heartburn and acid reflux disease.
Usually, the small gut would not have many micro organism as a result of meals is sterilised within the abdomen by acid and pancreatic enzymes, however this course of may be disrupted by numerous elements — together with remedy. Nonetheless, as a result of these medication suppress abdomen acid, ‘meals and micro organism aren’t killed off, and may attain the small gut’, says Mr Boyle, who labored as an NHS GI surgeon for 20 years and is medical director of the RefluxUK group of personal intestine clinics.
Proton-pump inhibitor medication are a number of the most generally prescribed within the nation. One among them, omeprazole, was the third mostly prescribed drug in 2019, with 31.5 million objects allotted. One other, lansoprazole, got here in sixth, at 26.7 million.
A number of research have discovered an affiliation between these medication and bacterial overgrowth, together with a evaluation of 19 research with 7,000 sufferers printed within the journal Gastroenterology in 2018, which confirmed a three-fold improve in threat of the issue with PPI use.

One other examine, within the European Journal of Medical Investigation in 2010, discovered 26 per cent of sufferers taking the medication for oesophagitis (irritation of the liner of the oesophagus owing to acid reflux disease) had developed SIBO after eight weeks. All had examined detrimental for the situation earlier than taking PPIs.
And a 2019 examine of 1,500 sufferers, printed within the Mexican Journal of Gastroenterology, discovered that 92 per cent of these prescribed these medication for gastric reflux and abdomen ulcers reported affected by IBS-type signs, with 82 per cent struggling bloating and 63 per cent complaining of stomach ache.
For 41 per cent of sufferers these had been new signs — ones that they had not had earlier than taking the abdomen acid drugs.
The identical examine discovered that those that had been then handled with the antibiotic rifaximin (a drug really useful for SIBO) reported the best enchancment in signs in contrast with these taking different medication, akin to antispasmodics.
Mr Boyle emphasises that PPIs are a great remedy ‘if utilized in the appropriate individuals to deal with the appropriate situations’, and that they’re efficient in stopping most cancers in individuals with Barrett’s oesophagus (a pre-cancerous situation related to extreme reflux).
Antibiotics might also set off bacterial overgrowth, as these — just like the stomach-acid suppressants — can alter the stability of the intestine microbiome, the colony of microorganisms within the intestine, permitting dangerous micro organism to overgrow within the small gut.
As a result of SIBO signs overlap with these of extra critical situations, akin to inflammatory bowel illness, coeliac illness and most cancers, these must be dominated out, says Mr Boyle.
‘However SIBO may be identified with a easy breath take a look at — out there on the NHS although not extensively,’ he says. ‘These may be despatched out as kits that individuals can do at house.’ The exams contain swallowing a sugary syrup (which incorporates lactulose, normally used as a laxative) and respiration into bottles over a few hours. These samples are despatched to the lab to test the degrees of hydrogen or methane. Excessive ranges point out that you will have the situation.
After the analysis is confirmed, remedy consists of antibiotics. A examine within the journal Gastroenterology in 2013 discovered that rifaximin can enhance SIBO signs in as much as 64 per cent of circumstances, however the drug is pricey (from round £110 for a ten-day course), so isn’t at all times extensively out there and is normally prescribed solely by specialists.
The identical examine discovered that cheaper, broad-spectrum antibiotics, akin to ciprofloxacin, metronidazole and tetracycline, had been efficient in 41 per cent of circumstances and may be tried as an alternative.
Peter Whorwell, a professor of medication at Manchester College, says it is a paradox that antibiotics could cause SIBO in addition to deal with it.
‘The concept is that when you’ve had an extended course of antibiotics and so they’ve killed off sure micro organism, a course of various antibiotics can then be used to kill off micro organism which have overgrown, particularly within the small gut the place they should not be within the first place,’ he says.
Making an attempt a low-FODMAP weight-reduction plan for 4 to 6 weeks below the supervision of a dietitian after a course of antibiotics might also assist, says Mr Boyle. ‘Eradicating the meals that micro organism feed on successfully starves them out.’
Some individuals want surgical procedure for reflux so that they now not need to take PPIs — as occurred with James, who had been taking the drugs for seven years.
In February final 12 months, he had Linx surgical procedure, the place a bracelet of magnetic beads is positioned across the oesophagus to bolster the weakened valve on the backside and forestall the acid reflux disease. His intestine signs improved and he now not takes acid reflux disease medication — he’s additionally going to begin a two-week course of rifaximin to sort out the cramps and bloating in his decrease intestine.
‘I am not fully cured however, after nearly 20 years of in search of solutions, the place I’m now’s so a lot better than being informed it is ‘simply’ IBS or being placed on PPIs, which might make the signs worse,’ he says.
There’s nonetheless controversy about how widespread SIBO is, how greatest to check for it and deal with it. There are additionally questions over the hyperlink to PPIs, with research, together with one within the journal Gastroenterology in 2016, displaying that sufferers with IBS had SIBO even once they did not take acid-suppressant drugs.
Dr Simon Smale, a marketing consultant gastroenterologist at Manchester College Hospital, says that the bacterial overgrowth is an ‘uncommon’ symptom of taking PPIs.
Professor Whorwell concurs, saying that round one in ten of the IBS sufferers he exams for SIBO has a optimistic consequence. ‘I do not dispute it exists — it positively does — however what I can not resolve on is whether or not SIBO is the trigger or an impact of the IBS,’ he says.
He has prescribed rifaximin to sufferers and, whereas some ‘definitely do enhance, sadly their signs do have a tendency to come back again once more’.
Dr Smale provides: ‘There are additionally points with the breath take a look at. It isn’t significantly particular and there are many variables that may have an effect on the result of the exams, together with not fasting for lengthy sufficient earlier than ingesting the lactulose.’
He suggests that almost all of people that see their GP about bloating is not going to have SIBO. ‘The commonest explanation for bloating is just consuming an excessive amount of,’ he says.
