Understanding Selenium Toxicity
I had no idea about the potential dangers of consuming excessive brazil nuts. This past week, I indulged in them frequently, believing they were a healthy source of protein and healthy fats, especially since I've been struggling with a low appetite and skipping meals. On Monday evening, I consumed around 25 brazil nuts. The next day, I experienced a peculiar metallic taste in my mouth, along with symptoms like faintness, nausea, weakness, and stomach discomfort. Fortunately, these issues resolved by the end of Tuesday, and I've felt normal since then; today is Friday. It was only today that I realized my symptoms were linked to selenium toxicity, or selenosis. While I feel fine now, I am anxious about the possibility of having caused some serious harm to my health and what the long-term effects might be. I have made the decision to avoid brazil nuts moving forward, but I cannot shake the worry that I have inadvertently poisoned myself. According to what I read, an overdose of selenium could lead to severe complications like heart problems, kidney issues, or liver damage. Should I consider consulting a healthcare professional, or is it likely that the selenium has already been eliminated from my system? I struggle with health anxiety, so any guidance would be greatly appreciated.

It's understandable to feel anxious after experiencing symptoms that may indicate selenium toxicity from consuming a large amount of Brazil nuts. However, given that your symptoms have resolved and it has been several days since your last consumption, the likelihood of long-term harm is low.
Explanation: Selenium is an essential mineral, and Brazil nuts are one of the richest sources. However, consuming excessive amounts can lead to toxicity, known as selenosis. Common symptoms include a metallic taste in the mouth, gastrointestinal upset, and neurological issues. If your symptoms have resolved, this suggests that your body has successfully processed the excess selenium.
While serious complications from selenium toxicity are possible with chronic excessive intake, your acute symptoms seem to indicate a temporary reaction rather than ongoing damage. The body usually eliminates excess selenium, and as you mentioned, you have not experienced any significant ongoing problems since then.
Next Steps:
-
Monitor Symptoms: Continue to pay attention to how you feel. If any new or concerning symptoms arise, like chest pain, unexplained fatigue, or similar symptoms to those you previously experienced, make a note of them.
-
Hydration and Nutrition: Stay well-hydrated and focus on a balanced diet that includes a variety of foods to support your overall health.
-
Avoid Brazil Nuts: You've already indicated you've decided to avoid Brazil nuts, which is a wise choice to prevent further risk.
-
Educate Yourself: Understanding what constitutes a safe amount of selenium can help reduce anxiety. The tolerable upper intake level for selenium for adults is 400 micrograms per day. A standard Brazil nut can contain anywhere from 68 to 91 micrograms of selenium, so moderation is key.
-
Consult a Professional if Needed: If your anxiety persists or if you're still worried about potential health complications, consider discussing your concerns with a healthcare professional for personalized advice and reassurance.
Remember, it's important to address health anxiety, and seeking support can provide you with peace of mind. You're taking proactive steps for your health, which is commendable!

My Relationship with Milk Consumption
For nearly two decades, I have predominantly relied on milk as my primary source of hydration, consuming around five liters daily. Although I recognize that this reliance might not be the healthiest choice, my low appetite has perpetually left me underweight. In the past, I attempted to transition to drinking water; however, I noticed a concerning drop in weight along with persistent fatigue. My inquiry is whether there exists a more nutritious method to obtain calories without resorting to solid foods, and ideally, without incurring high costs?
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.
