Quick answer: From Treatment of bilious diarrhoea This is achieved primarily through the use of bile acid-binding medicines (such as cholestyramine) and by adopting a special, low-fat diet. An accurate gastroenterological diagnosis, which often requires endoscopic examinations, is essential for appropriate treatment. The specialists at Endomedix help to alleviate symptoms through personalised, pain-free examinations.
Chronic digestive problems can make everyday life considerably more difficult. Many of our patients, particularly women in their fifties, often come to us with unpleasant abdominal symptoms that have lasted for weeks or months. Frequent, urgent bowel movements and bloating often cause anxiety. These symptoms can indicate a wide range of digestive disorders, one of the most common of which – yet one that often goes undiagnosed – is bile acid malabsorption.
From Treatment of bilious diarrhoea requires an accurate medical diagnosis. When the body’s digestive processes are disrupted, identifying the underlying causes of the symptoms is the first step towards recovery. To a layperson, the rapid-fire medical jargon can be daunting, but there is no cause for concern. Modern medicine now offers gentle, safe and extremely precise solutions.
At Endomedix’s gastroenterology centres, we take great care to ensure that our patients can undergo the necessary examinations in a calm and supportive environment. Our team possesses a high level of expertise in digestive system disorders, including the diagnosis of bile acid malabsorption. Our aim is to provide clear answers and effective treatment, thereby alleviating any fear associated with the examinations.
What exactly is biliary diarrhoea, and how does it develop?
Bile diarrhoea (medically known as bile acid malabsorption or bile acid diarrhoea) is a chronic condition caused by increased secretion in the large bowel. Normally, bile is produced in the liver, stored in the gallbladder, and then released into the small intestine during meals to aid the digestion of fats and fat-soluble vitamins (A, D, E and K).
The physiological role of bile in the digestive system
In a healthy digestive system, around 95 per cent of bile acids are reabsorbed in the final section of the small intestine – the so-called terminal ileum – and then return to the liver. This process is known as the enterohepatic cycle. Problems arise when this reabsorption process is disrupted for any reason.
When large quantities of unabsorbed bile acids pass into the large bowel, they irritate the intestinal mucosa. In response, the cells of the large bowel secrete water and electrolytes into the intestinal lumen. This increased fluid secretion results in loose, watery stools, i.e. secretory diarrhoea. In clinical practice, when the stool is analysed for electrolytes, the osmotic gap is found to be below 50 mOsm/kg, which clearly indicates a secretory process.
The three main types of bile acid malabsorption
Gastroenterology classifies bile acid malabsorption disorders into three main types based on their underlying causes. Determining the exact category is essential, as the Treatment of bilious diarrhoea It depends to a large extent on the underlying condition.
Type 1 (Secondary, of ileal origin): In this case, the problem is caused by physical damage to or the absence of the final section of the small intestine. This often occurs in cases of Crohn’s disease, or if the patient has undergone a terminal ileum resection (bowel surgery). Research shows that if the length of the removed section of intestine exceeds 100 centimetres, reabsorption is drastically reduced, leading to severe diarrhoea.
Type 2 (Primary or idiopathic): No clear organic lesions can be detected in the intestines here. The problem stems from a complex hormonal regulatory disorder. A hormone produced by the intestine, known as FGF19, normally suppresses the production of bile acids by the liver. If this feedback mechanism does not function properly, the liver continuously produces too much bile acid, which the small intestine is then unable to absorb completely.
Type 3 (associated with other digestive system disorders): A number of other gastrointestinal conditions can also alter the movement of bile through the intestines. These include the condition following cholecystectomy (removal of the gallbladder), coeliac disease, small intestinal bacterial overgrowth (SIBO), and microscopic colitis. In such cases, the anatomy of the intestine is intact, but its function differs from normal.
What are the most common symptoms of the condition?
Patients most commonly report chronic watery diarrhoea lasting for weeks or months. The urge to pass stools is often sudden and comes on like an attack, which places a significant psychological burden on patients. They are afraid to leave their homes and worry about using public transport or situations at work.
In addition to watery diarrhoea, common accompanying symptoms include increased gas production, bloating and cramp-like abdominal pain. As the absorption of fats may also be impaired due to a lack of bile, steatorrhoea (fatty, difficult-to-flush, foul-smelling stools) may occur. In the long term, this can lead to a deficiency in fat-soluble vitamins (vitamins A, D, E and K), which may result in fatigue, osteoporosis or blood clotting disorders. If you experience such symptoms, a thorough consultation with a specialist in gastroenterology It is essential for clarifying the problem.
Accurate diagnosis at Endomedix centres
An accurate diagnosis is the foundation of successful treatment. In our clinics, we use state-of-the-art diagnostic procedures to accurately assess the condition of your digestive system. Our specialist doctors have extensive experience in differential diagnosis, enabling them to reliably distinguish biliary diarrhoea from other conditions that cause similar symptoms (such as irritable bowel syndrome or infectious colitis).
Specialised tests and laboratory methods
One of the most reliable international methods for diagnosing bile acid malabsorption is the SeHCAT test. In this test, the patient swallows a special, labelled bile acid capsule, and after one week, the proportion of the ingested substance remaining in the body is measured using specialised equipment. If the value is low, this indicates increased bile acid loss. In Hungary and many other European countries, a therapeutic test is also frequently used in practice: the doctor prescribes a bile acid-binding medicine, and if the patient’s symptoms improve significantly within a few days, the diagnosis is confirmed. You can read more detailed information about this at Research data (PubMed) in the international guidelines published in its database as well.
The role of endoscopic examinations
Endoscopic examinations are very often necessary to rule out underlying organic causes (such as Crohn’s disease, microscopic colitis or coeliac disease). To carry out a thorough examination of the colon’s mucosa and to take tissue samples, the Colonoscopy offers the opportunity. If an examination of the upper section of the small intestine or the stomach is also warranted, your doctor Gastroscopy may recommend that it be carried out. In many cases, the two procedures can be carried out at the same time, which gastroscopy and colonoscopy We offer this to our patients.
Many people are apprehensive about these procedures because of the potential for pain or discomfort. It is important to know that, for professional reasons, at Endomedix we only use general anaesthesia; we do not use sedation. This means that, under the supervision of an experienced anaesthetist, you will be in a deep sleep throughout the procedure, thanks to a short-acting anaesthetic (propofol). You will feel no pain whatsoever, and within a few minutes of the examination being completed, you will wake up fully conscious. This method not only ensures your maximum comfort but also enables the doctor to make the most precise diagnosis whilst your digestive tract is completely relaxed.
How is bile-related diarrhoea treated in practice?
From Treatment of bilious diarrhoea a complex process based on several pillars. The aim of the treatment is to neutralise the bile acids that irritate the intestinal mucosa, to harmonise digestive processes and to bring about a lasting improvement in quality of life. The treatment plan is always tailored by the gastroenterologist to your individual condition.
Medication options and bile acid sequestrants
Bile acid sequestrants form the basis of the therapeutic pyramid. The most commonly used active ingredient is cholestyramine. These preparations physically bind to excess bile acids in the gut, thereby preventing them from irritating the wall of the large bowel and drawing water into the intestinal lumen.
Cholestyramine is available in powder form, which must be dissolved in liquid before taking. In many cases, its effects can be felt after just a few days: the consistency of the stools becomes firmer and the sudden urge to go is reduced. As these medicines can also bind to the active ingredients of other medicines, the doctor will specify exactly how long an interval is required before
