Inquiry About Bile Acid and Fat Malabsorption
Hello, I'm a 52-year-old woman and I underwent gallbladder removal more than 20 years ago. Shortly after the surgery, I began experiencing bile acid malabsorption (BAM), but I managed to improve over time. Recently, this condition was aggravated following a course of antibiotics and/or a Norovirus infection. I underwent a test and received the following results: 7AC4, Bile Acid Synthesis, S 137 H ng/mL (normal range 2.5-63.2). My gastroenterologist has confirmed that I definitely have BAM. Currently, my doctor is also investigating the possibility of fat malabsorption. I'm interested in understanding what can lead to fat malabsorption. Is it typical for individuals to experience both bile acid malabsorption and fat malabsorption simultaneously?

It's understandable that you have concerns about your bile acid malabsorption (BAM) and the possibility of fat malabsorption, especially after experiencing aggravation from your recent health events. Here’s a simplified overview of your situation:
Key Points:
- Bile Acid Malabsorption (BAM): BAM can lead to fat malabsorption because bile acids are essential for digesting fats.
- Simultaneous Conditions: It is common for individuals with BAM to also experience fat malabsorption.
- Contributing Factors: Infections, antibiotic use, and changes in diet can impact your digestive system and exacerbate these conditions.
Explanation:
Bile acids are produced by the liver and stored in the gallbladder; they aid in the digestion of fats. After gallbladder removal, some people struggle with BAM, meaning not enough bile acids are available to digest fats efficiently. When BAM is present, fat malabsorption can occur because undigested fats may pass through the digestive tract, leading to bloating, diarrhea, and nutrient deficiencies.
Having experienced a Norovirus infection and antibiotic treatment can disrupt the gut microbiome and potentially worsen BAM, which may also explain the current symptoms.
Next Steps:
- Dietary Adjustments: Focus on a low-fat diet until your symptoms improve. This can help minimize digestive issues related to fat malabsorption.
- Consider Supplements: Talk to your gastroenterologist about bile acid sequestrants (like cholestyramine) or digestive enzyme supplements that can aid in fat digestion.
- Monitor Symptoms: Keep a diary of your diet and symptoms. This can help identify trigger foods and patterns related to fat malabsorption.
- Discuss Further Testing: Your doctor may suggest additional tests, like stool tests or imaging, to assess fat absorption and overall digestive health.
- Stay Hydrated: Ensure you drink plenty of fluids, especially if you experience diarrhea, to prevent dehydration.
If your symptoms worsen or if you develop new symptoms, such as significant weight loss or persistent diarrhea, keep your doctor informed. Being proactive about your digestive health is important. Let me know if you have further questions or need more specific advice!

Could a Rotated Spine Be Responsible for My Swallowing Issues?
I am a 34-year-old female with no medications or notable medical history. Recently, I've been experiencing difficulty swallowing, known as dysphagia, for the past three to four weeks. During this period, I've only been able to consume soft foods. After undergoing a CT scan, I observed that my spine appears to be rotated. Is it possible that this spinal irregularity could be contributing to my swallowing problems? Thank you for your insights!
Experiencing Unexpected Skin Pain Without Visible Cause
I have consulted my physician regarding my unusual symptoms, but she was unable to provide a clear diagnosis. The only possibility she mentioned was fibromyalgia, which she believes may not apply to me due to my age. Although blood tests were performed, everything appeared normal. I'm a 29-year-old female dealing with obesity and have been managing my weight for a long time, currently with the help of Wegovy. I was a smoker and vaper for several years but have quit these habits since last year. Occasionally, when I touch, scratch, or bump against areas like my shoulders, upper arms, thighs, and lower back, I experience severe pain beneath my skin that doesn’t correlate with any visible injury. There are no marks or rashes left behind afterwards. The sensation resembles that of a bruise or the sharp pain felt when one strikes their hip. There are moments when the pain is so intense that I involuntarily cry out, but it only lasts for a brief period of 5 to 10 seconds. The occurrences are erratic; some days I can touch or scratch these areas without any discomfort, while other days, the pain strikes unexpectedly. This has been a recurring issue for approximately five years now. I'm reaching out to see if anyone might have insights or suggestions about what this could indicate.
Is My Health Declining?
At 25 years old, I’m a non-smoker who only indulges in alcohol during New Year’s celebrations. I manage a few health conditions including a nonverbal learning disorder, sensory processing difficulties, mild depression, dyspraxia, troublesome duodenal bile reflux, and irritable bowel syndrome (IBS) which has been in remission. I also experience sinus tachycardia and maintain low blood volume. I stand at 5 feet, 3 inches and weigh 119 pounds—a drop from 127 at the start of December. My current medications include buspirone and metoprolol, along with a B complex vitamin supplement. Approximately eight months ago, I began noticing unusually large black pieces in my bowel movements. Strikingly similar to bits of diced green pepper but entirely black, these chunks appear daily and vary drastically in size—from resembling a piece of rosemary to about the size of my thumbnail. Typically, I end up with a small handful of these peculiar pieces. The odor has become quite unpleasant, yet I only began to consider this recently. Not long after these occurrences started, I had a short period of worsened IBS symptoms—which was strange since I had been symptom-free for two years. Everything reverted to normal until December, when I had an unfortunate episode followed by a particularly rough evening shortly after consuming a lot of sugar. I anticipated feeling “iffy” for just a few days, but that feeling lingered. Now, nearly three months later, I’m frequently experiencing \\*almost\\* daily flare-ups and usually looser stools that range anywhere from a 6 to a fuzzy 4 on the Bristol Stool Chart. Moreover, I’m feeling slightly more discomfort outside of bowel movements than I have in the past. Attempts to tweak my diet have yielded no improvement. Given my relatively young age, I hope I’m not facing something as serious as colon cancer. The last time I stressed over abnormal bowel movements, a professional informed me I was simply excreting excess fat, which is quite common. I researched potential causes for my current situation, and it seems this black matter is not related to pepper, which is somewhat reassuring. I’m unsure how to determine if what I’m seeing is truly “tar-like.” Occasionally, I feel a pressure in my lower left abdomen, somewhat like trapped gas that persists for several days before easing up. Due to my propensity for unnecessary anxiety regarding my health, I felt compelled to share my situation here. Is this just typical IBS behavior, or should I be more concerned? My parents suggest I remain calm and avoid a GI consultation (as I will soon lose my insurance), but I would prefer to avoid another extensive testing journey. Unfortunately, my quality of life has diminished significantly in recent months, prompting my need for clarity.
Could This Be IBS or Something Else?
Greetings! I’m a 27-year-old male, standing at 172 cm and of European descent, currently using Iqos. My medical troubles began roughly four months ago, around October 5, 2025. Initially, I experienced intense back pain lasting for two days, which I recognized as kidney stone pain. To alleviate this discomfort, I took NSAIDs, predominantly Metamizole-Natrium. Afterward, I visited urgent care, where I was given Diclofenac and Monural, an antibiotic for urinary tract infections. I took one of each at night. **A couple of days later, I started experiencing several troubling symptoms:** - Frequent diarrhea (4-5 times a day, often watery) - Significant gas and belching - Persistent nausea that greeted me each morning, sometimes relieved by eating - A general sense of malaise - A loss of 5 kg (I dropped from 63 kg) because I lacked appetite, especially under stress. These symptoms developed quickly and intensified through October, fluctuating over time. Blood tests showed no abnormalities, with normal CRP levels. Then in November, I underwent a colonoscopy and gastroscopy. - I had three very small erosions, about 1-2 mm, in the terminal ileum, but no signs of inflammation. Histology revealed no pathological issues, all was well. - There was one small erosion in the sigmoid colon, with minor inflammation around it. Histological findings indicated small infiltration in the lamina propria but no chronic signs, leading to a diagnosis suggesting a high likelihood of infection. - The areas were healing, with fibrin present. The rest of my colon appeared healthy. The doctor attributed the ulcers to NSAID-induced damage. I was later diagnosed with LA-A GERD. Due to my anxiety about health, I spent the month consumed by fears of complications such as colon cancer, PC, or Crohn's disease. I finally found some relief and felt symptom-free for the subsequent two weeks. However, in December the troubles resurfaced, though to a lesser degree, with occasional loose stools—2-3 times for a few days— and lingering gas. My anxiety about Crohn's returned, and I mistakenly took Algopyrin Complex, which triggered additional stress. **In December, my primary worries included:** - Loose stools resembling Bristol type 5-6, mainly occurring once each morning - Excessive gas often felt trapped in my rectum - My weight stabilized at 62 kg **I underwent various tests:** - Negative results for Giardia and E. coli - Negative FIT tests - Negative MRI (everything appeared normal) - Negative MRE (all normal) - Calprotectin level measured at 18.7 - I was found to have low levels of B9 and Vitamin D, with B12 at 320 and LDL at 5.9 **Moving into January:** - I only had one bowel movement each morning, sometimes loose, but mostly firm in the past three weeks (Bristol 4), compared to my usual Bristol 2. - After meals, I often felt gas building in my rectum, sometimes getting stuck before eventually releasing. This gas, thankfully, rarely had an odor. - Mornings have been troublesome, as I needed to pass gas 2-4 times, and in bed at night, I felt bloated with gas movements. **What I have observed:** - No signs of blood in my stools - No pain - No nocturnal symptoms affecting my sleep - No extraintestinal symptoms - My weight has stabilized without additional loss after recovering some weight Overall, I feel fine, yet the worry about my condition persists in my mind. Previously, I would have bowel movements twice weekly, with little to no gas. It baffles me that I often wake up feeling this uncomfortable. My primary concern is whether I should be worried about Crohn's disease (which occupies my thoughts constantly) or if my symptoms might stem solely from anxiety. Currently, I'm taking the following medications and supplements: - Itopride (doctor suggested it for motility issues) - L-Glutamine - Curcumin - A B-complex supplement - Ashwagandha - I briefly tried rifaximin for three days, but it did not yield significant changes. - I had also experimented with antacids previously, though they proved ineffective. Thank you for your assistance in advance!
Seeking Relief from Mild Fecal Impaction: Should I Go to the ER?
At 20 years old, I find myself dealing with a frustrating issue: fecal impaction. It's not something I've faced before, or at least I can’t recall, but I’ve had chronic stomach difficulties throughout my childhood, including constipation from ages four to twelve. Recently, I've been experiencing more digestive challenges after a few years of feeling normal. Currently, I’m under the care of a gastroenterologist, and we’re working on diagnosing the underlying problems. For about five days now, I haven't been able to relieve myself. While I’ve had considerable gas, that’s been the only symptom. Today has been particularly difficult; I’ve spent the last 11 hours in the bathroom grappling with severe discomfort and impaction. Each attempt to relieve the situation is excruciating, to the point where my body is resisting the effort—it’s so painful that I find myself in tears. I imagine this is what birth must feel like. I suspect this intense fear and pain are remnants of my past struggles, as for many years I’ve feared using the bathroom due to the agony it causes. Despite trying various remedies like Miralax mixed with coffee, a bullet suppository, and even a manual approach with gloves, nothing is yielding results. I’m genuinely tempted to head to the emergency room and ask them to put me under so they can help me without the pain. My mother suggests they would likely opt for a liquid suppository treatment like they did during my childhood, which was quite traumatic. I’m torn—it feels like the ER might be my last resort, but I'm concerned they won’t take me seriously since my situation doesn’t seem dire. How foolish would it be to bring up wanting sedation? I desperately want to avoid this pain; it’s becoming increasingly difficult, and I’m fighting back tears from the frustration. Can they truly provide sedation for this type of issue even when it isn’t severe? I worry that my parents might react negatively to my quest for relief and think I’m being dramatic. I’m utterly drained and don’t know where to turn. When there’s no painful push against my body, I can’t even sense the severity of the issue, yet, I am experiencing leakage, leaving me unsure. Would it be unreasonable to pose this question to the doctors in the ER? I apologize if this message is jumbled; I’m also dealing with a migraine, making it hard to focus. For context, my daily medications include phentermine, iron supplements, and vitamin D. I stand at 5’4” and currently weigh 204 pounds as part of my ongoing weight loss journey.
