Understanding My Upcoming Chest CT Scan: What Are They Investigating?
At 19 years old, I (female) have been facing bouts of breathlessness and a sensation of tightness in my chest, particularly noticeable after exercise. My new general practitioner has suggested a pulmonologist for further investigation, suspecting I might have exercise-induced asthma since I've recently transitioned from pediatric care. I have no history of vaping or cigarette smoking, although I've experimented with marijuana on a few occasions, but I ceased this activity after my doctor’s appointment to avoid interfering with any tests. Following my visit, an X-ray was performed which revealed that my lungs are hyper-inflated with some air trapping present. Interestingly, though, the X-ray indicated that the pulmonary vessels in the lower lobe of my left lung were not visible. I underwent spirometry along with a few other asthma-related assessments, but the findings were inconclusive, with my results actually being above the average range. I was prescribed Ventolin and Breo; unfortunately, these have not provided relief. My symptoms seem to strike unexpectedly—whether I'm exercising or even while just at rest. It feels as though the condition has intensified since my last consultation, as I'm struggling to yawn or eat without missing a breath. Now, my doctor has scheduled a non-contrast CT scan, but I'm left uncertain about its purpose. What exactly might they be aiming to uncover? Is this measure simply a precautionary step? To summarize: I’m experiencing breathlessness, with my lung X-ray showing hyper-inflation and air trapping, but negative spirometry results and obscured lower lobe pulmonary vessels. I’m curious about the objectives of the upcoming non-contrast CT scan. What could the doctor be investigating?

Your upcoming CT scan is a critical next step in understanding the underlying causes of your breathlessness and chest tightness. Given the complexity of your symptoms, including hyper-inflated lungs, air trapping, and the inconclusive spirometry results, the scan aims to provide clearer insights.
Main Points:
- Purpose of the CT Scan: The non-contrast CT scan will help your doctor examine your lungs in more detail.
- What the Scan May Reveal: The scan can identify structural abnormalities, inflammation, or other conditions that aren't visible on an X-ray.
Explanation:
A CT scan provides cross-sectional images of your lungs, allowing for a more detailed assessment than an X-ray. Since your X-ray showed hyper-inflation and air trapping, the CT scan aims to explore potential causes, such as:
- Asthma or Other Chronic Lung Conditions: The scan can help confirm or rule out exercise-induced asthma or conditions like bronchiectasis or COPD (unlikely at your age but can occur).
- Airway Obstructions: It can reveal if there are any blockages or abnormalities in the airways.
- Lung Tissue Health: The condition of lung tissue can be assessed for signs of inflammation, infections, or other structural issues.
- Pulmonary Vessels: Since your X-ray indicated that the pulmonary vessels in your lower left lung weren't visible, the CT scan may help evaluate vascular structures.
Next Steps:
- Stay Hydrated: Drink plenty of fluids leading up to your CT scan to help ensure your body is well-prepared.
- Monitor Symptoms: Keep a record of when your breathlessness occurs, how severe it feels, and any triggers or patterns you notice. This information can aid your doctor in understanding your condition better.
- Avoid Irritants: Continue to steer clear of smoking, vaping, or exposure to secondhand smoke, as they can exacerbate lung issues.
- Follow Up on Medications: Continue taking your prescribed medications (Ventolin and Breo) as directed. If they are not providing relief, keep your doctor informed about your experiences.
It's understandable to feel anxious about further testing, but remember that the goal is to gain better clarity on your health. This step can lead to more effective management of your symptoms. If you have any further questions or if your symptoms worsen, don't hesitate to communicate openly with your healthcare provider.

Seeking Help for Ongoing Health Issues
I am reaching out in desperation for assistance! I'm wondering if anyone else has encountered similar health concerns or could recommend medications or specialists I should consider consulting. I'm truly at a loss and need guidance. As a 23-year-old male vegetarian weighing around 48 kg and standing at 5’4”, I have struggled with being underweight since my childhood. This condition has left me feeling utterly drained and overwhelmed. I’m eager to make a change but feel lost regarding where to begin or which healthcare professional to consult. In my youth, I was diagnosed with asthma, which has significantly improved; however, I continue to deal with low immunity, as I frequently catch colds and coughs from minor exposure to cold environments. Additionally, I’ve noticed that for the past few years, my body temperature feels abnormally high compared to those around me. I experience heat more acutely than my peers. Previously, I was quite active and could walk 4–5 kilometers daily without difficulty. Nowadays, even a short walk of 1–2 kilometers or climbing a few flights of stairs leaves me out of breath and exhausted. Even on days of little physical exertion, I feel weak and lethargic, as though all my vitality has been drained. My appetite has always been low, despite my efforts to increase it. I struggle to consume what would be considered an average meal for someone my age. Just two chapatis or a small bowl of rice or lentils fills me up completely, and attempting to eat more causes discomfort. I often find it perplexing how others manage to eat such larger portions. Dining out has become a challenge for me since even half a plate feels overwhelmingly full. Being extremely slender has made it difficult to find clothing that fits well and has adversely impacted my confidence over the years. For around 15 years, I have hesitated to take photographs of myself. Social and professional circles often regard me as younger than I am, sometimes even as a child, which has contributed to my feelings of invisibility and insecurity. My sensitivity to heat has intensified over the last few years. In seemingly normal room temperatures, I start sweating profusely while those around me remain comfortable. During cold weather, even in temperatures as low as 8°C, I don’t wear warm clothing, as I sweat excessively and feel anxious about overheating. The discomfort can escalate to a point where I feel faint from the heat. In my workplace, where the air conditioning is set at a standard temperature, I find it challenging. I begin to sweat visibly, leaving my clothes damp and prompting coworkers to inquire about my wellbeing. I often feel breathless and anxious that I might collapse if I remain there too long. This makes it very difficult to stay at the office or use public transportation, as even air-conditioned buses can feel uncomfortably warm to me. Over the past year, my situation has deteriorated further. I can no longer tolerate hot or even mildly spiced home-cooked meals, which I used to enjoy without issues. Now, even mildly spiced foods lead to excessive sweating, reddening of my face, and an intense burning sensation in my mouth, akin to consuming overly spicy dishes. As a result, my food intake has diminished even more. I often face ridicule for my dietary limitations, and I’m growing weary of trying to explain my condition, especially when my own family doesn't fully grasp the depth of my struggles, which adds to my distress. I am sharing my story because I truly need help. I wish to identify the underlying issues with my health and seek proper medical attention. If anyone has experienced similar problems or can recommend a suitable type of medical professional to consult, I would greatly appreciate your guidance and support during this challenging time. Thank you. 😭
Interpretation Request for Recent Spinal NM Bone Scan
Hello, doctors. I'm reaching out for your insights regarding a recent NM bone scan of my spine. I've previously undergone a similar scan in 2022, and I'd like to compare the two. To provide context, I am a 29-year-old female weighing 100 kg, and I've been diagnosed with conditions including endplate sclerosis, spinal stenosis, cervical bone spurs, degenerative disc disease (DDD), and mild scoliosis. My medication regimen consists of several prescriptions. Unfortunately, my next appointment with my general practitioner is still a few weeks away, so I would appreciate your assessments on how the latest scan compares to the previous one. Thank you in advance for your help!
Unexpected Eye Issues: Headache and Double Vision Concerns
A 33-year-old female, measuring 1.67 meters in height and weighing 55 kilograms, residing in the Netherlands, experienced a sudden onset of symptoms. Last evening, shortly after dinner, my partner complained of a slight headache localized at the rear of her head. Along with this discomfort, she encountered double vision and noticed her right eye deviating outward. Interestingly, when she shut either eye, the double vision resolved, enabling her to see without distortion. We rushed her to the emergency room later that night. The medical team conducted a variety of assessments, including physical examinations, neurological evaluations, visual tests, and laboratory analyses. Fortunately, all results were normal. However, the doctors found it peculiar that her right eye exhibited normal movement and accurately tracked a pen in all directions when her left eye was closed. The medical opinion suggested that it may be a migraine-related episode, a condition she has experienced previously. Nonetheless, she insists that this feels unlike any migraine she has had in the past. A teleconsultation with a neurologist is scheduled for Monday to arrange an MRI should the symptoms continue. The doctors advised that if her symptoms worsen, we should return to the hospital immediately. Fortunately, after a night's rest, her vision had returned to normal by morning, the headache had subsided, and her right eye was aligned properly. I am understandably concerned, particularly due to her assertion that this does not resemble a typical migraine. Is it possible that this is indeed a migraine, or could it be indicative of another underlying issue? Thank you for your attention to this matter.
