Lower Resting Heart Rate Observations
I am a 26-year-old male, weighing 133 kg (286 lbs) and standing at 190 cm (6’3”). Recently, I have been taking Nexium, specifically 20 mg each day, but I stopped this medication just yesterday. Since November, I have been following a calorie deficit diet and have successfully lost approximately 18 kg (40 lbs). Over the past week, I’ve noticed a significant decrease in my resting heart rate, which now ranges from 45 to 55 beats per minute while relaxing on the couch, and from 55 to 60 beats per minute when I'm driving. Meanwhile, my blood oxygen saturation has been hovering between 95% to 99%. Previously, my resting heart rate was around 65 bpm when lying down and roughly 75 bpm when driving. Interestingly, I’ve observed that even after consuming a meal, including those high in carbohydrates, my heart rate remains stable at about 60 bpm while seated rather than spiking as I typically experienced in the past. I visited the emergency room on March 17 because I felt extremely fatigued. After undergoing two troponin tests, an EKG, X-rays, and various blood tests, the medical staff assured me that everything appeared normal. I am uncertain if these changes are linked to the discontinuation of the PPI (nexium/esomeprazole) or if they could stem from the calorie deficit I have been maintaining. While I do engage in physical exercise, I do not participate in marathon running, high-intensity interval training, or any form of strenuous cardio workouts.

You’ve experienced a notable drop in your resting heart rate along with significant weight loss, and it’s understandable to feel concerned about these changes. Let's break down what might be happening and what actions you can consider.
Main Points:
- A lower resting heart rate can be a result of factors like weight loss, physical fitness, or the absence of certain medications.
- Changes in heart rate following a meal also suggest improvements in your body’s response to food.
- It’s essential to monitor your symptoms and follow up if you experience any concerning signs.
Explanation: Resting heart rates of 45 to 60 beats per minute can be normal for some individuals, especially if they are physically fit or have lost weight, as you have. Weight loss and dietary changes can lead to improved cardiovascular health, which may explain the decrease in your heart rate. Stopping Nexium (a proton pump inhibitor) likely has little direct impact on your heart rate, but it’s always worth being aware of how your body responds to medication changes.
Your blood oxygen level of 95% to 99% is within a normal range, which is reassuring. The immediate concern arises only if you start to experience symptoms like dizziness, fainting, or extreme fatigue.
Next Steps:
- Monitor Your Heart Rate: Continue to observe your heart rate and note if it falls below 45 bpm or if you begin to experience symptoms like dizziness or fatigue.
- Stay Hydrated and Maintain Nutrition: Ensure you are eating balanced meals with adequate hydration. A diet that supports heart health includes plenty of fruits, vegetables, whole grains, lean protein, and healthy fats.
- Engage in Light to Moderate Exercise: If you are not already doing so, consider incorporating activities like walking or cycling into your routine, as this can further improve your cardiovascular fitness without excessive strain.
- Keep a Journal of Symptoms: Track any changes in how you feel—especially regarding energy levels, heart rate, or new symptoms. This may help you relate your symptoms to lifestyle changes.
- Consult If Symptoms Persist: If you notice a concerning trend or develop new symptoms, consider reaching out to a healthcare professional for a thorough re-evaluation.
Your proactive approach to health has already yielded positive results, and these changes can be a normal part of your body's adaptation. However, staying aware and attuned to your body is key. Let me know if you need more details or specific guidance on any of these points!

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. 😭
Is an 85-pound Weight Healthy for a Woman Who is 5’1"?
A friend of mine stands at 5 feet 1 inch tall and has a delicate frame, tipping the scales at 85 pounds.

She maintains an active lifestyle, exercising regularly and following a nutritious diet, yet she doesn't overindulge. This leaves me pondering whether her health is indeed in check.
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.
