Seeking Clarity on Postural Tachycardia Symptoms
Greetings everyone, This is my inaugural post, so I apologize in advance if I overlook any details. I'd like to clarify that while postural orthostatic tachycardia syndrome (POTS) has been a topic of discussion lately, I'm not actively seeking a diagnosis; I simply want to understand what's going on with my body. As a resident of the UK, I recognize that my healthcare options may be somewhat constrained. For as long as I can recall, I've experienced moments of blackout vision upon standing and persistent lightheadedness. Initially, it was manageable, and my doctors suggested that it was likely due to anemia, leading me to take iron supplements for an extended period. I'm not certain if this is pertinent, but it provides context for my situation. I'm a 26-year-old female, and over the past couple of years, I've noticed a significant worsening of my symptoms, along with the emergence of new issues. The weakness I feel has increased, making it difficult for me to walk any distance beyond ten minutes without fearing a fainting episode — although I haven't actually fainted. For instance, I used to walk to a nearby supermarket which takes approximately twelve minutes, but I now find that my heart rate significantly spikes almost immediately upon starting to walk. While that alone wouldn't be so bothersome, I also experience severe breathlessness and a dizziness that intensifies, particularly in hot and humid conditions. This was particularly evident during my time using the metro. Climbing stairs leaves me feeling extremely lightheaded, and my balance often feels compromised, giving the sensation that all the blood has drained from my head. It’s as if someone dims my vision, and I struggle to think clearly. Though it's not always so severe if I manage my pace and allow myself rest breaks, tasks like vacuuming become daunting due to the bending and moving around; my muscles fatigue rapidly, leading to breathlessness and the need for frequent pauses. I also encounter blackout sensations when I stand up too quickly. To self-manage these episodes, I often consume salt when the symptoms peak and elevate my legs, which seemingly revitalizes me within moments. Coffee appears to be beneficial as well, potentially due to its effect on my blood pressure, which tends to run low. Recently, I've started using a smartwatch to track my heart rate, which I realize may lack precision; however, it typically shows a resting heart rate of around 70-80 beats per minute. Upon standing, it can surge to about 110 bpm, which I understand can be normal, yet engaging in any activity I label as strenuous can push it to 130 bpm, with uncertainties of reaching 150 bpm on some occasions. After undergoing various tests without obtaining substantial answers, I've come here to seek validation regarding my concerns. My medical journey began with a routine 12-lead ECG; the doctor claimed there was nothing notable, although I had other ECGs done previously that indicated no significant findings, apart from a childhood murmur. An echocardiogram yielded normal results, and I also wore a Holter monitor for 24 hours, during which I noted instances of my symptoms. In a follow-up phone consultation, the doctor mentioned that the Holter monitor captured a normal heart rate range of 60-160 bpm, which should not raise any flags and indicated no abnormalities. This was quite puzzling to me as I had documented several occasions where I felt peculiar. I also expressed my skepticism about whether reaching 160 bpm while simply walking is indeed normal. Despite voicing my concerns beyond heart rate — regarding my other symptoms — the doctor inquired about my fluid and caffeine intake, suggesting I limit the latter while increasing my water consumption to three liters a day. While I agreed these are generally positive adjustments, I was left wondering if these modifications would resolve my symptoms. I don’t recall his exact response, but it offered little assistance. The doctor further asserted that my symptoms might be subjective, mentioning I was likely perceiving a heart rate spike when climbing stairs rather than it actually occurring — a claim I found untrue since I actively monitor my heart rate myself. He hesitated to label my condition as POTS, stating the evidence wasn't compelling enough, particularly since sustained high heart rate readings weren't evident in the Holter results. I clarified that during episodes of elevated heart rates, it typically returns to baseline after ceasing activity; however, I tend to rest due to feeling unwell, which could prolong the elevated heart rate. He described my situation as neurological rather than cardiological, which left me perplexed considering his specialization in cardiology and heart failure. Ultimately, he suggested I could be referred to neurology centers if I desired, yet emphasized self-management strategies, almost implying that I likely have POTS without formally diagnosing it. Overall, the entire consultation felt largely unproductive. In the discharge notes, the doctor used dismissive language, implying my symptoms were a matter of perception rather than genuine occurrences. He also inaccurately documented that he advised increased salt intake during our conversation. Despite this, I have managed to secure a referral to a neurology center and have scheduled a follow-up appointment for April. I’m reaching out to gather insight on what other medical professionals think regarding my condition. I would also appreciate suggestions on how to manage my symptoms effectively and any important points to address during my upcoming neurology consultation. Additionally, for context, I have existing conditions that include hypermobile Ehlers-Danlos syndrome, irritable bowel syndrome, and autism.

Thank you for sharing your detailed experience. It sounds like you're dealing with a complex set of symptoms that are understandably concerning and frustrating. I commend your commitment to understanding your health better.
Based on your description, it seems like you might be experiencing symptoms consistent with Postural Orthostatic Tachycardia Syndrome (POTS), which can lead to lightheadedness, increased heart rate upon standing, and other related issues. While I can't diagnose, I can provide insights and practical suggestions for managing your symptoms and preparing for your neurology appointment.
Key Points:
-
Symptoms Consistency: The lightheadedness upon standing and persistent breathlessness align with POTS symptoms. Your heart rate responses indicate a potential dysregulation of your autonomic nervous system.
-
Self-Management Strategies: You’ve already identified some effective self-management strategies, such as increasing salt intake and fluid consumption. These can help manage blood volume and blood pressure.
Next Steps for Management:
-
Hydration & Salt: Continue to drink plenty of fluids—aim for 2-3 liters daily, and consider electrolyte solutions if needed. Increasing salt intake can help, but do so cautiously and ideally under medical supervision.
-
Gradual Position Changes: To mitigate lightheadedness, practice changing positions slowly. When standing, consider tensing your leg muscles to help blood flow.
-
Compression Garments: Wearing compression stockings can aid in blood circulation, preventing blood from pooling in your legs when you stand.
-
Frequent Breaks: During activities that provoke symptoms, take regular breaks to rest. Walking or standing might be easier if you alternate with seated or resting positions.
-
Temperature Control: Since you mention worsening symptoms in hot and humid conditions, find ways to stay cool, such as using fans or staying in shaded areas.
-
Physical Activity: Engage in gentle, regular exercises like swimming, which can be easier on your body and still beneficial for circulation without excessive strain.
Preparation for Your Neurology Consultation:
-
Symptom Diary: Keep a detailed log of your symptoms, including triggers, duration, and any strategies that alleviate them. This can help the neurologist understand your condition better.
-
Discussion Points: Prepare to discuss your overall health history, current symptoms, and your goals for treatment. Consider asking specific questions about potential treatments for dysautonomia or related conditions and lifestyle changes that might help.
-
Previous Test Results: Bring any test results and notes from past consultations, as they will give the neurologist important context about your case.
It's important to feel validated and to seek further help if your symptoms persist or worsen. You're doing a great job advocating for your health, and I'm hopeful that your upcoming consultation will provide further clarity and support. If you have more questions or need further guidance, feel free to reach out.

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.
Eight Years of Persistent ‘Hunger’—Is It a Functional Gut Disorder?
Greetings everyone, I’m a 28-year-old woman standing at 5 feet 4 inches, and for nearly eight years, I have struggled with a constant, hollow sensation in my upper abdomen that resembles hunger. Here are some key points about my experience: - This sensation arises between meals or soon after I have eaten. - It gets momentarily better after eating but eventually returns. - Though it feels like hunger, I know it's not genuine hunger. - Mornings are especially tough as the sensation intensifies. I maintain a regular meal schedule and consume enough calories without any restrictions. Currently, I find it difficult to trust my hunger cues, so I'm tracking my calorie intake. I do not take any medications and have previously used proton pump inhibitors without any noticeable improvement. Additionally, I neither smoke nor consume alcohol. Visits to my general practitioner have yielded no definitive diagnosis, with much of the feedback being centered on dietary adjustments. I am currently facing a waiting period of approximately eight months for a gastroscopy. Strangely, I also notice that I feel particularly weak during my workouts, despite my calorie intake being sufficient. Has anyone else faced a similar long-term issue? Did you find it to be functional dyspepsia, gastritis, visceral hypersensitivity, or something entirely different? Were you able to obtain assistance through a gastroenterologist, a dietitian, or therapy? Thanks for your insights!
Rapid Heart Rate During Illness
A 27-year-old male, standing at 6 feet 3 inches tall and weighing 275 pounds, presents as non-smoking with a medical regimen including buspirone, sertraline, and Nexium. He does not consume alcohol or use illicit drugs. His medical background highlights anxiety and a previously noted Wolff-Parkinson-White (WPW) pattern observed on an ECG in 2023, without any prior ablation or recorded arrhythmias. On February 5th, I visited the emergency room after experiencing a sudden and alarming increase in my resting heart rate to approximately 130 beats per minute while at home. This spike was particularly distressing given my history of chronic anxiety. Reflecting on the earlier part of the day, I recall experiencing mild body aches, a cough, and a sensation akin to a low-grade fever, which now appear to have been early signs indicating I was becoming ill. Once at the emergency room, the medical team administered 10 mg of propranolol, resulting in a gradual decrease in my heart rate from 130 to the mid to upper 90s over a span of about one hour and 45 minutes. The ECG revealed only sinus tachycardia, and notably, the doctor informed me that the WPW pattern from 2023 was no longer evident. All laboratory tests returned normal results with standard electrolyte levels, kidney function (eGFR at 108), and a complete blood count showing only a typical stress response characterized by elevated neutrophils and reduced lymphocytes, alongside normal urine tests. There were no indications of dehydration, infection, thyroid irregularities, or arrhythmia. After returning home, it became clear that I was battling a viral infection. I experienced chills, extensive body aches, and fever peaking at 101.8°F, as well as a cough with medium brown mucus (not excessively dark or bright red). I have not experienced shortness of breath or wheezing at rest. Notably, my heart rate has paralleled my fever. When my fever ranges between 101°F and 102°F, my resting heart rate typically aligns between 105 and 125 beats per minute. Conversely, as my fever declines into the 99°F range, my heart rate drops to the 80s and 90s. Under normal circumstances, my resting heart rate hovers around 60 beats per minute. Currently, I am measuring a temperature of approximately 100.6°F to 100.8°F, with a heart rate around 110 to 115 beats per minute. About an hour ago, I took Tylenol, and am staying hydrated and resting. The only discomfort I feel is due to persistent coughing. I have a few inquiries: - Is this heart rate fluctuation typical during a viral infection accompanied by fever? - Should I expect to see an elevated heart rate persist even during sleep when my fever is elevated? - Is there any cause for concern regarding my previous WPW even though the recent ECG indicates that pattern is no longer present? Thank you for your assistance.
