Experiencing Bloody Diarrhoea Following a Fever
Hello everyone, I’m a 35-year-old male with a history of anxiety, small intestine bacterial overgrowth (SIBO), Hashimoto’s thyroiditis, and subclinical hypothyroidism. My current medications include sertraline and levothyroxine. Last Thursday, after returning from the gym, I started to feel widespread aches similar to flu symptoms. Upon waking on Friday, this discomfort persisted, and by the afternoon, I began experiencing diarrhoea accompanied by stomach cramps; these cramps typically occur just before a bowel movement. Despite still feeling unwell on Saturday morning, I had to travel that day. To manage the situation, I took Imodium, which proved effective in preventing any unfortunate incidents during my seven-hour trip. However, during the journey, I experienced significant chills, leading me to suspect I might have had a fever. This morning (Sunday), I found myself awake at 2:30 AM, once again needing the toilet, and the diarrhoea continued. When I visited the bathroom at around 7:30 AM, I was alarmed to notice blood in my stool, particularly distressing since I had hardly eaten anything since Thursday—just a clear liquid. Fortunately, the body aches and headache I was enduring have significantly diminished, and I haven't needed to take any more paracetamol. I still find myself having bowel movements every couple of hours, with blood noted each time. Earlier, I managed to eat a banana and a slice of toast. Although I struggle with health anxiety, I must admit I have remained surprisingly collected during this episode. Is it possible that this is merely a typical stomach virus? Currently, I am away from home but still within the UK, and I can reach out to NHS 111 if needed. By the way, I recently finished a course of antibiotics to treat an infected hangnail about a month ago—might this be relevant? Thanks for your input! 🙏

It sounds like you’re experiencing some concerning gastrointestinal symptoms, including bloody diarrhea following a fever, and it’s great that you’re reaching out for guidance. While it could potentially be due to a viral infection or another gastrointestinal issue, the presence of blood in your stool raises the need for caution. Here are the main points to consider:
Main Points
- You may have a viral or bacterial infection causing your symptoms.
- The presence of blood in your stool requires careful attention.
- It’s essential to stay hydrated and monitor your symptoms closely.
Explanation
Given your recent history of flu-like symptoms and diarrhea, it’s possible that you could be facing a gastrointestinal infection, possibly exacerbated by your recent antibiotic use, which can disrupt the normal gut flora and lead to conditions like antibiotic-associated colitis. However, the presence of blood in your stool, especially when it follows fever, can indicate potentially more serious issues, like a bacterial infection or an inflammatory condition.
Next Steps
-
Stay Hydrated: Focus on drinking clear fluids, like water, broth, or rehydration solutions, to prevent dehydration from diarrhea.
-
Monitor Symptoms: Keep an eye on how often you are having bowel movements and any changes in your symptoms. Note any new symptoms such as worsening pain, further blood in your stool, or persistent fever.
-
Seek Medical Advice: Contact NHS 111 as soon as possible to discuss your symptoms further. It is important to get personalized advice from a healthcare professional who can take a full history and suggest any necessary investigations or treatments.
-
Avoid Certain Foods: Stick to bland foods initially (like bananas, toast, or rice) until your symptoms settle. Avoid fatty, sugary, or spicy foods that could irritate your digestive tract.
-
Keep Your Doctor Informed: When you contact NHS 111 or your doctor, mention your recent antibiotic use and any other health conditions (like SIBO and thyroid issues) as they may influence your care.
You’re handling this situation with remarkable calmness despite your health anxiety, which is commendable. Please take this situation seriously, and I encourage you to reach out for medical advice soon. Stay safe!

Concerns About Abdominal Discomfort
To start with, I feel compelled to mention that I struggle with severe health-related obsessive-compulsive disorder, which leads me to intensely focus on any symptoms I experience, resulting in unnecessary worry. Recently, I began to experience some discomfort in my abdomen, specifically in the area just below my right breast, which has now evolved into tenderness upon touch. This soreness is located beneath my rib cage, and I haven't experienced any changes in my appetite or feelings of nausea. My last bowel movement occurred on Thursday, and as of this morning, the discomfort has shifted slightly, now positioned just above my belly button. I had a regular bowel movement this morning and was able to take a walk without any issues. The pain only manifests when I cough or during the transitions between sitting and standing. Initially, I was concerned about the possibility of a hernia, but I understand that the pain associated with a hernia typically does not shift in location like mine seems to. I should also note that I am classified as overweight and have been living with gastroesophageal reflux disease (GERD), for which I’m taking a proton pump inhibitor. Fortunately, my heartburn symptoms have remained stable, largely influenced by my dietary habits. Over the past year, I've dealt with some weight fluctuations due to medication side effects and stress (ranging from 330 pounds to 275 pounds and back to 310 pounds). Thankfully, I have not encountered vomiting or any changes in my bowel movements. I would appreciate any insights or advice on this matter.
Lymph Nodes Observed in Abdominal CT Scan
A 26-year-old female, standing at 5'1" and weighing 70 kg, who does not smoke and drinks alcohol occasionally, has been experiencing gastrointestinal problems characterized by alternating periods of constipation and softer stools since January 24th. Additionally, she was diagnosed with a bladder infection on February 3rd, which was treated with a single dose of antibiotics totalling 3000 mg. She sought emergency medical attention due to significant discomfort in her lower left back, initially feeling colicky before becoming a constant dull ache, leading to an overnight stay for an abdominal CT scan the following morning. The findings from this scan have caused her some concern, particularly regarding identified lymph nodes. **Medical Findings:** Diagnosis: Lumbosacral radiculopathy and fecal impaction. **Treatment Approach:** The patient has been prescribed spasmolytic analgesics and will undergo further radiological evaluation. **CT Scan Results:** The low-dose native abdominal CT revealed normal appearances of the kidneys and urinary tract on both sides, with no signs of urinary retention or kidney stones in the renal pelvis or ureters. However, a few small, nonspecific mesenteric lymph nodes were detected in the mesenteric root and perizocecal areas, along with small inguinal lymph nodes on both sides. There is also no indication of appendicitis, and the colon contains a moderate volume of stool. The remainder of the low-dose CT findings are within normal limits. **Ultrasound Findings:** The abdominal ultrasound indicates grade I ectasia of the left renal pelvis, while no abnormalities were noted in the left renal pelvis, and the bladder was observed to be empty following urination. **Next Steps:** A referral for further urological evaluation is recommended alongside maintaining adequate hydration, with analgesics suggested if pain management is necessary.
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.
