Seeking Clarity on My Pulmonary Test Results
I am a 29-year-old female weighing 300 pounds, with a background of smoking and vaping, and I'm feeling quite anxious about my pulmonary test results. I’m often experiencing dry heaving and on occasion, I either vomit or cough up blood. I have a CT scan scheduled for my lungs at the end of the month, but I would appreciate any guidance on interpreting my results. The flow volume loops did not meet the criteria set by the American Thoracic Society (ATS). Although my Forced Vital Capacity (FVC) is deemed normal, mild airflow obstruction was noted. This could be a typical variation for a person who is otherwise healthy, since my Forced Expiratory Volume in one second (FEV1) remains normal. Further clinical evaluation is necessary. While my Vital Capacity (VC) is within range, the Functional Residual Capacity (FRC) shows a decrease. On the other hand, the Ratio of Residual Volume to Total Lung Capacity (RV/TLC) is normal, and my Total Lung Capacity (TLC) is also satisfactory. Notably, the Diffusing Capacity of the Lung for Carbon Monoxide (DLCO) passed the ATS criteria, indicating normal diffusing capacity.

Your concerns about your pulmonary test results are completely valid, especially given your symptoms and background. Here’s a breakdown of the key points from your results and what they might indicate, along with some immediate steps you can take.
Key Points of Your Test Results:
-
Normal FVC but Mild Airflow Obstruction: While your Forced Vital Capacity (FVC) is normal, the mild airflow obstruction suggests that there may be slight difficulty in pushing air out, which can occur for a variety of reasons, including smoking or asthma-like conditions.
-
Decreased FRC and Normal DLCO: A decreased Functional Residual Capacity (FRC) might suggest that you are not able to keep as much air in your lungs after exhaling, which can be common in certain lung conditions or mechanical issues related to weight or posture. However, your normal DLCO indicates that the gas exchange capability of your lungs is functioning well.
-
Importance of Clinical Evaluation: The statement about needing further clinical evaluation is important. It means that your results indicate that while some lung function aspects are normal, a milder obstruction requires a follow-up to pinpoint the cause and relevant treatment.
Next Steps:
-
Monitor Your Symptoms: Keep track of your symptoms (dry heaving, vomiting, coughing up blood) and any triggers that might worsen them. Note how often they occur and their severity. This information is crucial for your upcoming evaluation.
-
Lifestyle Adjustments:
- Quit Smoking and Vaping: If you haven’t already, consider seeking support to stop smoking/vaping, as this will significantly improve your lung health, regardless of your current test results.
- Stay Hydrated: Drink plenty of fluids, as they can help soothe your throat and reduce coughing.
- Avoid Irritants: Try to avoid exposure to secondhand smoke, strong odors, or allergens which can irritate your lungs.
-
Prepare for Your CT Scan: Make a list of any questions or concerns you have regarding the scan and your symptoms to discuss with your healthcare provider. Understanding what the CT scan is looking for can help ease your anxiety.
-
Follow-Up: Ensure you schedule any necessary follow-up appointments to review your CT results and discuss any further testing or treatments needed.
Acknowledgment:
It's understandable to feel anxious about these results and symptoms, especially given your background and the complexity of interpreting pulmonary function tests. Remember that you are taking proactive steps towards understanding and improving your health. Please feel free to reach out with any further questions or if you need additional information.

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?
Mother's Breathing Difficulties After Tree Dust Encounter on Cruise
My mother, a 53-year-old woman living in Australia without known health issues but with a 25-year history of heavy smoking, recently embarked on a cruise through the Pacific islands. During a guided tour on one of the islands, the tour guide struck a tree to convey traditional knowledge, which caused dust to billow into the air, and my mother inadvertently inhaled it. She described the sensation of the dust entering her throat and lungs, and shortly after, she developed severe cold-like symptoms and a cough that became so intense it made breathing difficult. Now, less than a week back from the trip, she's still battling a persistent and harsh cough. This evening, while attempting to vacuum, she mentioned having trouble breathing. Despite my concerns, her stubborn nature means she plans to wait a week before consulting a doctor—but I believe immediate action is necessary. Smoking approximately 15 cigarettes daily, she has struggled with a chronic smoker's cough for several years; however, the intensity of her current cough is unprecedented. During our phone conversation, she could not speak for more than 10 seconds without breaking into coughs. I worry that she might have contracted a respiratory infection or pneumonia. Her partner caught a milder version of her cold and has since recovered, leaving her condition looking increasingly severe. Regrettably, I cannot recall the name of the island or the specific tree involved in this incident. Given the alarming symptoms, does this seem indicative of a respiratory infection or pneumonia? For years, I have fretted over the possibilities of emphysema and lung cancer, but she is resistant to seeking medical help, fearing that it would lead to advice about quitting smoking—something she reacts to like a rebellious teenager. We are also trying to persuade her partner to urge her to visit a doctor as soon as possible.
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
Struggling with Frequent Respiratory Infections
Hello! Since 2020, I have been falling ill with one of four conditions: COVID-19, pneumonia, bronchitis, or tonsillitis, experiencing two bouts of pneumonia in just the last half year. Throughout my life, I have managed asthma while playing sports at a collegiate level, seldom relying on my inhaler. Generally, I consider myself to be in good health. At the age of 28, as a woman, I am quite active and not prone to frequent illness. However, since the wildfires in Los Angeles, I feel like I'm becoming ill more frequently. I consulted with a pulmonologist last December who suggested a CAT scan, which ultimately revealed no significant abnormalities. I also have routine lab work done every six months, and those results do not indicate any issues either. At this point, I find myself feeling increasingly frustrated and uncertain about what steps to take next. If anyone has thoughts, guidance, or recommendations, I would greatly appreciate your input!
