In this expert survey, leading UK gastroenterologists shared their real-world experience diagnosing and treating over 1,000 patients with BAD, revealing strong consensus on using SeHCAT testing to confirm the diagnosis and bile acid sequestrants as first-line treatment. The experts agreed that patients with functional diarrhoea, irritable bowel syndrome with diarrhoea (IBS-D), or diarrhoea after gallbladder removal should be tested for BAD, and that most patients with a positive test will respond well to treatment—with response rates exceeding 70% in the most severe cases.

Bile acids are digestive fluids produced by the liver and stored in the gallbladder. Normally, they help digest fats in the small intestine and are then reabsorbed in the final section of the small intestine, called the terminal ileum. When this reabsorption process fails—or when the liver produces too many bile acids—the excess spills into the colon, where it triggers fluid and electrolyte secretion, leading to diarrhoea.\u003c\/p\u003e\n\n\u003cp\u003eDoctors have recognised this condition for over 50 years. It was originally called \"cholerheic enteropathy,\" and it has also been known as bile acid malabsorption (BAM) or bile salt malabsorption. Today, the preferred term is BAD, and it is increasingly understood to cause a wide range of gastrointestinal symptoms—not just diarrhoea.\u003c\/p\u003e\n\n\u003cp\u003ePatients with BAD often experience a variety of troublesome symptoms, including:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIntermittent or persistent diarrhoea\u003c\/li\u003e\n  \u003cli\u003eIncreased bowel frequency\u003c\/li\u003e\n  \u003cli\u003eUrgency (feeling like you must rush to the toilet)\u003c\/li\u003e\n  \u003cli\u003eNocturnal defaecation (waking up at night to pass stool)\u003c\/li\u003e\n  \u003cli\u003eExcessive flatulence\u003c\/li\u003e\n  \u003cli\u003eAbdominal pain\u003c\/li\u003e\n  \u003cli\u003eFaecal incontinence (involuntary loss of stool)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eBAD can arise from several causes. In some patients, it follows ileal resection (surgical removal of part of the terminal ileum), active Crohn's disease, cancer chemotherapy, or pelvic irradiation (radiation therapy). This is called secondary BAD. In other patients—those with no identifiable cause—the condition is called primary or idiopathic BAD. Research shows that primary BAD forms a subset of patients diagnosed with chronic functional diarrhoea or irritable bowel syndrome with predominant diarrhoea (IBS-D). Most of these patients have no defect in bile acid absorption itself; rather, the problem appears to be hepatic (liver) overproduction of bile acids. This overproduction has been linked to increased blood levels of a bile acid precursor called C4 (7α-OH-4-cholesten-3-one) and to impaired feedback from a hormone called fibroblast growth factor 19 (FGF19), which is produced in the ileum.\u003c\/p\u003e\n\n\u003cp\u003eDespite being relatively common, BAD is often underdiagnosed. A survey by patient groups has shown poor recognition among healthcare professionals, with diagnostic delay often exceeding 5 years. This means many patients suffer unnecessarily for long periods without a proper diagnosis or effective treatment—a large unmet need in symptom control.\u003c\/p\u003e\n\n\u003ch2 id=\"methods\"\u003eStudy Methods: How the Expert Survey Was Conducted\u003c\/h2\u003e\n\n\u003cp\u003eThe UK Bile Acid Related Diarrhoea Network (UK-BARDN) was established in 2017 as a forum for researchers who had recently published work on BAD\/BAM.

SeHCAT (tauroselcholic acid) is a nuclear medicine test developed in the 1980s. It involves swallowing a capsule containing a small amount of radioactive selenium-labelled bile acid (75Se-radiolabelled 23-selena-25-homotaurocholate). A scan is performed on day 1 and again on day 7 to measure how much of the labelled bile acid is retained in the body. Low retention means excess bile acids are escaping into the colon—confirming BAD.\u003c\/p\u003e\n\n\u003cp\u003eThe second most popular diagnostic approach was a \u003cstrong\u003etherapeutic trial\u003c\/strong\u003e—prescribing a bile acid sequestrant (BAS) medication and seeing whether symptoms improve—which was chosen by \u003cstrong\u003e85%\u003c\/strong\u003e of respondents as a diagnostic method.

If you have been diagnosed with IBS-D and your symptoms are not well controlled, it may be worth asking your doctor whether BAD testing could be appropriate for you.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSecond, diagnosis can change everything.\u003c\/strong\u003e The survey clearly showed that experts prefer to confirm the diagnosis with SeHCAT testing before starting treatment. They recognised the value of a clear diagnosis rather than simply prescribing medication on a trial-and-error basis. Recent studies cited in the paper have shown that early SeHCAT testing has significant economic advantages, reducing unnecessary cross-sectional imaging (CT\/MRI scans), repeated colonoscopies, and unnecessary trials of expensive medications. For patients, this means fewer invasive tests and a faster path to effective treatment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThird, treatment is effective—especially for severe BAD.\u003c\/strong\u003e The predicted response rates are encouraging. For patients with severe BAD (SeHCAT retention below 5%), 100% of experts predicted treatment success rates over 70%, with more than half predicting over 90% response. Even for moderate disease, the vast majority of experts predicted good responses. If you have confirmed BAD, there is a strong chance that treatment will significantly improve your symptoms.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFourth, there is a clear pathway for patients who don't respond fully.\u003c\/strong\u003e If the first medication doesn't work, experts recommend a step-by-step approach: increase the dose, add loperamide, switch to a different sequestrant, and consider a low fat diet. This means there are multiple options to try before giving up on treatment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFifth, treatment should be individualised.\u003c\/strong\u003e Starting doses vary widely among experts (from 2 g to 12 g daily of colestyramine, for example), and dosing at night is preferred by many.

The authors note, however, that the UK has greater experience of BAD diagnosis and management than most other countries precisely because of the wider use of SeHCAT.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe sample size was small.\u003c\/strong\u003e With only 21 respondents, all of whom were members of the UK-BARDN network with published research on BAD, the survey may not fully represent the views of all UK gastroenterologists. Other UK gastroenterologists who were not part of this network might have different opinions. The authors acknowledge this but note that where there is consensus among experts, the findings should still help inform future decisions and guidelines.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExperience with alternative tests was limited.\u003c\/strong\u003e The respondents had limited experience with faecal bile acid tests, C4, and FGF19, so these tests were not a major consideration in this survey. Previous research suggests that low C4 and high FGF19 can have a role in the diagnostic pathway and may help select patients for further testing, but these require further validation.\u003c\/p\u003e\n\n\u003ch2 id=\"recommendations\"\u003eRecommendations: Actionable Advice for Patients\u003c\/h2\u003e\n\n\u003cp\u003eBased on this expert survey, here are practical recommendations for patients who may have bile acid diarrhoea, as well as for those already diagnosed:\u003c\/p\u003e\n\n\u003ch3\u003eIf you have chronic diarrhoea and haven't been diagnosed:\u003c\/h3\u003e\n\u003col\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrack your symptoms.\u003c\/strong\u003e Note stool frequency, consistency (using the Bristol Stool Form Scale), urgency, incontinence, and whether symptoms are constant or intermittent.

It can happen when the ileum fails to reabsorb bile acids or the liver makes too many. Recognised for over 50 years, it may be primary or secondary to surgery, Crohn's disease, or other conditions.\u003c\/p\u003e\n\u003ch3\u003eWho should be tested for bile acid diarrhoea?\u003c\/h3\u003e\n\u003cp\u003eExperts recommend testing for BAD in people with functional diarrhoea, irritable bowel syndrome with diarrhoea (IBS-D), or diarrhoea after gallbladder removal. Other associated conditions include ileal resection, Crohn's disease, right hemicolectomy, pelvic radiotherapy, microscopic colitis, bariatric surgery, and small intestinal bacterial overgrowth. If you have chronic loose stools and any of these, ask your doctor about testing.\u003c\/p\u003e\n\u003ch3\u003eHow is bile acid diarrhoea diagnosed?\u003c\/h3\u003e\n\u003cp\u003eThe preferred test is SeHCAT, a nuclear medicine scan that measures retention of a labelled bile acid over 7 days. Low retention confirms BAD. A therapeutic trial of a bile acid sequestrant is also used by 85% of experts. Blood tests for FGF19 or C4 are less commonly recognised but may aid diagnosis in some settings.\u003c\/p\u003e\n\u003ch3\u003eWhat does a SeHCAT test involve?\u003c\/h3\u003e\n\u003cp\u003eYou swallow a capsule containing a small amount of radioactive selenium-labelled bile acid. A scan is done on day 1 and again on day 7 to see how much is retained. Low retention means excess bile acids are escaping into the colon, confirming BAD. It is safe and used widely in the UK.\u003c\/p\u003e\n\u003ch3\u003eWhat treatments are available for bile acid diarrhoea?\u003c\/h3\u003e\n\u003cp\u003eBile acid sequestrants are first-line treatment, with colestyramine used by 95% of experts. Colesevelam is a common alternative. Starting doses vary, and many experts prefer dosing at night. Take other medications 1 hour before or 4 hours after the sequestrant to avoid interactions. Your doctor may adjust the dose.\u003c\/p\u003e\n\u003ch3\u003eWhat if treatment for bile acid diarrhoea doesn't fully work?\u003c\/h3\u003e\n\u003cp\u003eIf symptoms persist, experts recommend: increasing the dose, adding loperamide, switching to an alternative bile acid sequestrant, and trying a low fat diet of 40g per day. Some also suggest avoiding high FODMAP foods. These steps can be combined and should be discussed with your healthcare provider.\u003c\/p\u003e\n\u003ch3\u003eI have chronic diarrhoea and was told I have IBS-D, but treatment isn't working. Should I get a second opinion about bile acid diarrhoea?\u003c\/h3\u003e\n\u003cp\u003eIf you have been diagnosed with IBS-D or functional diarrhoea and your symptoms include frequent loose stools, urgency, or incontinence, a second opinion may be worthwhile. Bile acid diarrhoea is commonly overlooked, and diagnostic delays often exceed five years. A large proportion of IBS-D patients actually have bile acid diarrhoea, and SeHCAT testing can confirm it. Treatment with bile acid sequestrants is effective, with predicted response rates above 70% even for moderate disease.
