Understanding Secondary Polycythemia and Sleep Apnea
A 30-year-old woman has undergone blood testing, revealing elevated levels of hemoglobin and hematocrit, with consistent results upon retesting. A sleep apnea evaluation was subsequently conducted, which classified her condition as moderate, leading to a referral to a specialist in pulmonary medicine. To better prepare for the upcoming appointment, here are some questions to consider: - Is the main objective of my visit to get fitted for a CPAP machine, or will there be additional assessments? - Could my sleep apnea be responsible for the increased hemoglobin and hematocrit, or might secondary polycythemia play a role? If so, would therapeutic phlebotomy be beneficial in my case? Additionally, it would be wise to think about other inquiries that might arise during the consultation with the pulmonary doctor. It's worth noting that I am not currently on any medication and do not have any other health concerns apart from this issue.

It’s great that you’re preparing for your upcoming appointment regarding your elevated hemoglobin and hematocrit levels, as well as your moderate sleep apnea. Let’s break this down into key points to consider for your visit.
Main Points
- Objective of Your Visit: Expect an assessment of both your sleep apnea and blood work.
- Connection Between Sleep Apnea and Blood Levels: Your sleep apnea could indeed contribute to increased hemoglobin and hematocrit levels.
- Possible Treatment Approaches: Understand the rationale behind potential CPAP therapy and therapeutic phlebotomy options.
Explanation
-
Objective of Your Visit: During your appointment, the doctor will likely evaluate your sleep study results and discuss treatment options. While fitting you for a CPAP machine is possible, the doctor may also conduct additional assessments, such as a thorough respiratory examination or further blood tests, to understand the link between your sleep apnea and elevated blood counts.
-
Connection Between Conditions: Moderate sleep apnea can lead to lower oxygen levels during sleep, triggering the body to produce more red blood cells in an effort to improve oxygen transport. This condition is known as secondary polycythemia. It’s important to explore if your elevated hemoglobin is solely due to sleep apnea or if there are other underlying causes that might need investigation.
-
Treatment Approaches:
- CPAP Machine: This will help manage your sleep apnea by delivering a constant stream of air to keep your airways open while you sleep.
- Therapeutic Phlebotomy: If your doctor determines that your elevated hemoglobin is significant and potentially harmful, they might suggest therapeutic phlebotomy, a procedure that involves drawing blood to reduce red blood cell count.
Next Steps
-
Prepare Questions for Your Doctor:
- What specific tests will be done during my visit?
- How do you determine whether my hemoglobin and hematocrit levels are directly related to sleep apnea?
- What are the expected outcomes of using a CPAP machine, and how do we monitor its effectiveness?
- Could therapeutic phlebotomy be necessary, and what would be the criteria for that?
-
Document Your Symptoms: Keep track of any symptoms related to sleep apnea (like snoring, gasping during sleep, or daytime fatigue) and how they correlate with your blood test results. Bring this information to your appointment, as it will help the doctor assess your condition more thoroughly.
-
Lifestyle Adjustments: While awaiting the appointment, consider implementing lifestyle changes that can positively affect sleep apnea, such as maintaining a healthy weight, avoiding alcohol close to bedtime, and sleeping on your side.
I hope this helps you feel more prepared for your visit! If you have further questions or need clarifications on any points, feel free to ask.

16-Year-Old Dealing with Scoliosis and Breathing Issues: Seeking Advice
As a 16-year-old male, I’m currently coping with gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS), while also having been diagnosed with an S-shaped type of scoliosis. During my latest spinal evaluation in 2023, the findings revealed: - Thoracic curve: 25°, bending towards the right - Lumbar curve: 45°, bending towards the left For many years—long before my scoliosis diagnosis—I have been experiencing sporadic shortness of breath, approximately once a month or even less frequently. In June, I visited a clinic because I was suffering from a persistent cough following a viral infection. The attending physician conducted an X-ray and subsequently referred me to the emergency room after she suspected I might have a pleural effusion. Upon arriving at the ER, a CT scan was performed, revealing that the curvature of my spine was exerting pressure on my left lung. Initially, my oxygen saturation level was recorded at 88%. However, due to my shaky hands, the physician questioned the accuracy of this reading. Upon retaking the measurement, my oxygen saturation stabilized between 94% and 99%, and arterial blood gases indicated normal levels. Later on, I consulted a senior pulmonologist who recommended that I prioritize appointments with spine specialists rather than pulmonary care providers, and proceeded to order a spirometry assessment. I chose to delay this test due to frequent panic attacks, fearing these might negatively impact the results. However, I am now set to undergo the spirometry test in three weeks and would like to know if anyone else has experienced a comparable situation. I’m also feeling anxious about the potential for pulmonary hypertension. To provide further context, in April, I underwent two echocardiograms: - The first one, carried out by a junior doctor, indicated an estimated pulmonary artery pressure (EPASP) of 48 mmHg. - The second one, just two days later, was performed by a more experienced cardiologist and showed an EPASP of 30 mmHg alongside a tricuspid regurgitant velocity (TRV) of 2.64 m/s. Additionally, I have concerns about possibly having a pectus deformity, or conditions like Swyer-James-MacLeod syndrome, even though these have not been formally diagnosed. Given all of this, how concerning do my lung conditions appear? Can scoliosis by itself account for these symptoms? Moreover, does this situation escalate potential concerns regarding pectus deformity or Swyer-James-MacLeod syndrome?
Considering Trazodone with 2nd Degree AV Block Mobitz Type I: A Personal Inquiry
Recently, I consulted with a psychiatrist on the recommendation of my therapist. During that visit, I was prescribed sertraline, starting at 25 mg for the first week before increasing to 50 mg, alongside trazodone at a similar dosage, to help with my sleeplessness. After undergoing an EKG, which revealed a first-degree AV block, further testing with a Holter monitor indicated a second-degree AV block. Two cardiologists advised me against using trazodone, leading me to solely take sertraline, which I have been on for 12 days without any adverse effects so far. Just two days prior, I had a follow-up appointment with my psychiatrist. To my surprise, she informed me that a lower dose of trazodone, specifically 25 mg, could be an option. I've been contemplating trying it given that the AV block isn't causing me any issues – I wouldn’t have known about it had it not been for the EKG – and also because melatonin isn’t consistently effective for me. I'm reaching out for advice since I haven't come across much information online about the safety of trazodone in conjunction with this type of AV block; most findings seem to focus on trazodone overdose. Thank you for your insights! (Please excuse any language errors; English is not my native tongue.)
Seeking Relief: Ongoing Ear and Facial Discomfort After Two Weeks of Respiratory Illness
I am currently experiencing day 14 of a lingering respiratory illness, the origins of which remain unclear. It initially presented with relentless sneezing and a persistent runny nose, accompanied by a low-grade fever ranging from 99 to 100 degrees. Additionally, I have suffered from facial and sinus pain, conjunctivitis, intense headaches, fatigue, and general body aches. After visiting urgent care, I underwent tests for COVID-19, influenza types A and B, and RSV, all returning negative results. The doctor provided me with azelastine; however, he indicated that no further interventions were necessary at that time. While the sneezing and excessive nasal discharge subsided within a few days, I continue to endure headaches, congestion, generalized aches, and overwhelming fatigue at this two-week mark. Moreover, I've recently started experiencing pain in my left ear, with persistent sinus discomfort on that same side. Occasionally, I find myself running a fever of around 99 degrees. Unfortunately, I am unable to make an appointment with my primary care physician for another couple of weeks. I am contemplating whether another visit to urgent care would be worthwhile. Is there any potential relief available for my ear pain? Due to my allergy to aspirin and NSAIDs, I can only use Tylenol, which hasn't alleviated the discomfort. I suspect that I may simply need to ride out this troublesome illness, but could the symptoms indicate a bacterial infection that warrants an antibiotic treatment? Additional Information: - Age: 60 - Gender: Female - Height: 5'2" - Weight: 120 lbs - Ethnicity: White/Asian - Duration of symptoms: 14 days - Pain location: Left ear and left side of the face - Relevant medical history: MCAS, POTS, hEDS, one adrenal gland - Current medications: loratadine, famotidine, fluticasone, prescription potassium, metoprolol, montelukast, azelastine
Seeking Help for Severe Duodenal Reflux Gastritis
Hello, f30. I'm reaching out for guidance on how to effectively communicate my condition to a gastroenterologist. I’m experiencing significant duodenal reflux, resulting in bile and fluid accumulating in my stomach. After only a few bites of food, my stomach fills with liquid rather than emptying properly, leading to prolonged retention that causes irritation. Over time, my digestive function has steadily declined. I’ve lost 13 kilograms and now find it challenging to consume even a single glass of water or two meals a day. While I don't experience nausea, I'm plagued by continuous liquid retention and a persistent dull burning sensation that is worsening, accompanied by a swallowing reflex that feels like water pooling in my throat. Previous symptoms, such as sporadic but intense feelings of hunger that were alleviated by eating, as well as brief periods of gnawing discomfort, were ignored during earlier consultations. I later realized these could indicate a mild form of erosive gastritis. Regrettably, the delay in proper diagnosis and the misleading advice from alternative healthcare providers have exacerbated my situation, something that is quite difficult to accept given that I may have been treatable at that time. In contrast, I’ve observed online communities where people suffering from gastritis report more severe experiences than I initially had, leading me to unknowingly consume foods that exacerbated my condition. Many healthcare professionals attribute my issues to anxiety or stress. Although I acknowledge that worrying about my health has not contributed positively to my situation, I have not seen a direct correlation between stress and physical symptoms. Moreover, I have no history of mental health disorders. I would have been open to a diagnosis of gastritis along with a stress-related component, but the biological factors have never been thoroughly explored. I felt as though I was on a path to recovery but, lacking essential knowledge, I inadvertently consumed inappropriate foods and drinks. My primary challenge lies in articulating the severity and progressive nature of my condition without coming off as self-diagnosing or exaggerating my symptoms. I wish to convey the abnormal and uncontrollable accumulation of liquid and its damaging effects, yet I am continually dismissed because I still consume food and my digestion appears normal. I seek an assessment of whether the fluids I'm retaining are from my stomach or the pancreas. A year ago, an endoscopy indicated a healthy stomach (only a month following an injury), yet my health has deteriorated since, a point that was previously dismissed. I now recognize this decline to be linked to more severe bile reflux, triggered by my injury, which has led to a gradual loss of stomach function. I am exploring the possibility of the DeMeester duodenal switch surgery, but it’s not feasible in my country. I hope to attain the necessary diagnosis to discuss this possibility. How can I express to a doctor that my issues are no longer merely psychological? I am unable to eat or drink the necessary amount for survival, and relying solely on a once-daily meal is not sustainable. How should I approach asking for further investigation or an open dialogue regarding future treatments, including the potential for surgery, when prior referrals have been declined without a full understanding of my situation? I appreciate any advice you might have regarding my language or strategy when addressing this. A candid discussion concerning the risks and benefits of surgery in my circumstance is crucial. Additionally, has my stomach lost neural function? Are the fluids I’m experiencing pancreatic, or are they unusual protective secretions from the stomach? It is vital for me to gain a realistic perspective on my future. I realize that whenever I suspect bile, the subsequent day becomes noticeably more challenging. Can surgery potentially reverse this damage, or is that a futile hope? Those are the types of questions I want to explore with a medical professional.
Breathing Difficulties
Hello everyone. I’m a 25-year-old male, standing at 1.80 meters and weighing 110 kilograms. I take 75 mg of Sertraline daily and have never been a smoker. Recently, I’ve experienced some unusual symptoms and seek your advice. Approximately a week and a half ago, I noticed what felt like a weakness or fatigue on the right side of my face. I didn’t think much of it at first. However, the following day, I began to sense a change in my breathing. Although I could still manage to take deeper breaths, I felt a peculiar pressure in my chest, particularly after eating. This made me more mindful of my breathing patterns. While this pressure subsided somewhat on its own, this morning I experienced something concerning. After using the restroom, I instinctively tried to take a deep breath, but my body seemed to cancel it, only allowing a small intake of air. When I forced myself to take a deeper breath, I was able to, but the volume of air I could inhale felt reduced compared to before. The difference is slight but noticeable. Additionally, after attempting several deep breaths in quick succession, I've developed a persistent urge to breathe deeply every few seconds, and this sensation has not abated for the last 20 to 30 minutes.
