Bile Acid Malabsorption
Bile acid malabsorption (BAM) is a condition where the digestive system cannot properly absorb bile acids. Bile acids are produced by the liver to help with the digestion and absorption of fat. When the intestine cannot absorb the bile acids properly, it can lead to symptoms such as watery diarrhea, abdominal pain, and bloating. BAM can be caused by a variety of factors, including certain medications, gastrointestinal surgeries, and other medical conditions. Treatment for BAM typically involves medication to help bind the excess bile acids and alleviate symptoms. Dietary changes, such as avoiding certain fatty foods, may also be recommended. BAM can be a challenging condition to diagnosis and manage, but with proper treatment, most people are able to manage their symptoms and improve their quality of life.
Symptoms of Bile Acid Malabsorption
What are the common symptoms of Bile Acid Malabsorption?
Common symptoms of Bile Acid Malabsorption include diarrhea (often chronic and watery), urgent need to have a bowel movement, abdominal pain or discomfort, bloating, gas, urgency, and frequent bowel movements.
How does Bile Acid Malabsorption cause diarrhea?
Bile Acid Malabsorption causes diarrhea by interfering with the normal function of the digestive system. Bile acids, which are normally reabsorbed in the small intestine and then recycled by the liver, are not reabsorbed properly in people with this condition. This leads to an excess of bile acids in the colon, which can irritate and inflame the lining of the colon, leading to diarrhea.
Does stress play a role in Bile Acid Malabsorption symptoms?
Stress may play a role in exacerbating symptoms of Bile Acid Malabsorption, as stress can affect digestion and the normal functioning of the digestive tract. However, more research is needed to fully understand the relationship between stress and Bile Acid Malabsorption.
What factors contribute to Bile Acid Malabsorption?
Factors that contribute to Bile Acid Malabsorption include damage to the lining of the small intestine (such as from Crohn`s disease or celiac disease), removal of the terminal ileum (a part of the small intestine), and other conditions that affect the bile acid cycle, such as liver disease.
Can certain medications cause Bile Acid Malabsorption symptoms?
Certain medications, such as those used to lower cholesterol levels (such as cholestyramine and colestipol) and to treat chronic diarrhea (such as loperamide), can cause Bile Acid Malabsorption symptoms. These medications can interfere with the normal recycling of bile acids, leading to an excess in the colon and resulting in symptoms such as diarrhea.
Diagnosis of Bile Acid Malabsorption
What tests are available for diagnosing bile acid malabsorption?
There are several tests available for diagnosing bile acid malabsorption. The SeHCAT test is considered the gold standard for diagnosing this condition. Other tests like the serum C4, plasma fibroblast growth factor 19 (FGF19), and fasting serum bile acids have also been used, but their diagnostic accuracy is not as high as the SeHCAT test.

Can a diagnosis of bile acid malabsorption be confirmed through blood tests?
No, a diagnosis of bile acid malabsorption cannot be confirmed through blood tests alone. (Source: https://www.gastrojournal.org/article/S0016-5085(16)35263-1/fulltext)
What role does a SeHCAT scan play in diagnosing bile acid malabsorption?
A SeHCAT scan is a nuclear medicine test that measures the absorption of a radioactive substance called selenium-75 homocholic acid taurine (SeHCAT) in the intestines. A person with bile acid malabsorption will have reduced SeHCAT retention. A SeHCAT scan is considered the gold standard for diagnosing bile acid malabsorption.

Is endoscopy used in the diagnosis of bile acid malabsorption?
Endoscopy is not used in the diagnosis of bile acid malabsorption. However, endoscopy can be performed to rule out other gastrointestinal conditions that can cause similar symptoms. (Source: https://www.gastrojournal.org/article/S0016-5085(16)35263-1/fulltext)
How is a breath test used to diagnose bile acid malabsorption?
A breath test can be used to diagnose bile acid malabsorption. This test involves drinking a solution containing a non-absorbable, synthetic bile acid called glycocholic acid labeled with carbon-14, and then collecting breath samples over a period of time. The breath samples are analyzed to determine how much of the labeled bile acid was absorbed in the intestines. A higher amount of labeled bile acid in the breath indicates bile acid malabsorption.

Treatments of Bile Acid Malabsorption
What are the common medications used to manage bile acid malabsorption?
The common medications used to manage bile acid malabsorption include bile acid sequestrants, proton pump inhibitors, and opioid antagonists. Bile acid sequestrants such as cholestyramine and colestipol bind to bile acids in the intestines and prevent their reabsorption, which can help reduce diarrhea and other symptoms of bile acid malabsorption. Proton pump inhibitors such as omeprazole and lansoprazole can reduce the secretion of bile acids in the stomach, which can help alleviate symptoms. Opioid antagonists such as naloxegol and naltrexone can also help improve symptoms by decreasing bowel movement frequency.
How effective are bile acid sequestrants in treating bile acid malabsorption?
Bile acid sequestrants have been shown to be effective in treating bile acid malabsorption. According to a study published in Gut, cholestyramine was found to be effective in reducing diarrhea and improving quality of life in patients with bile acid malabsorption. Another study published in Alimentary Pharmacology & Therapeutics also showed that colestipol was effective in reducing diarrhea and improving bowel function in patients with bile acid malabsorption.
What dietary modifications can aid in the management of bile acid malabsorption?
Dietary modifications that can aid in the management of bile acid malabsorption include reducing intake of fatty and spicy foods, increasing intake of soluble fiber, and avoiding foods that trigger symptoms. According to the International Foundation for Gastrointestinal Disorders, soluble fiber can help absorb excess bile acids in the intestine, which can reduce symptoms. Foods that are high in soluble fiber include oats, barley, lentils, and berries. It is also important to avoid foods that trigger symptoms, such as caffeine, alcohol, and dairy products.
Can antibiotics be used to treat bile acid malabsorption?
Antibiotics can be used to treat bile acid malabsorption in some cases. According to a study published in Gut, rifaximin was found to be effective in reducing diarrhea and improving quality of life in patients with bile acid malabsorption. However, it is important to note that antibiotics should only be used under the guidance of a healthcare professional.
Is surgery a viable option for those with severe bile acid malabsorption?
Surgery is not typically a viable option for those with bile acid malabsorption. According to the American Society of Colon and Rectal Surgeons, surgical intervention is only considered in rare cases when medical management is unable to control symptoms, and it involves removal of the terminal ileum, which is where most bile acid absorption occurs. However, this surgery is not without risks and complications, and should only be considered after careful evaluation by a healthcare professional.
Prognosis of Bile Acid Malabsorption
What is the long-term prognosis of Bile Acid Malabsorption?
Bile Acid Malabsorption is a chronic condition that can cause long-term symptoms that affect the quality of life, but generally, it is not life-threatening. There is no cure for this condition, but with proper management, patients can manage their symptoms and improve their long-term prognosis.
Can the severity of Bile Acid Malabsorption affect the prognosis?
