Experiencing Heart Palpitations and Blurred Vision
Hello, I’ve been encountering sporadic episodes where I can distinctly sense palpitations in my chest. Just last week, one of these occurrences was coupled with a fleeting episode of darkened, blurred vision. Each instance lasts merely a few seconds, and I've noticed these unusual sensations only recently. I'm planning to seek medical advice soon since it's making me quite anxious, but I thought I'd share my situation here in hopes of gaining some perspective from professionals before my appointment. A bit about myself: I’m a 22-year-old biological male, Caucasian, and an ex-smoker—I've been smoke-free for a month now. I consume alcohol on a casual basis, roughly once or twice weekly. There's no significant family history of cardiac problems, aside from my father having hypertension; however, my blood pressure has consistently been within the normal range upon medical evaluation. I engage in recreational workouts and maintain an active lifestyle, not to mention I follow a relatively healthy diet. I'm about 5'10" and weigh 160 pounds. Currently, I take 10mg of Olanzapine every day, which is an antipsychotic. The most recent episode occurred shortly after I finished a can of Monster energy drink. However, I can't recall if I had consumed any caffeine during the blurred vision incident from last week. There have been some recent stressors in my life, though it’s been manageable compared to previous challenges, and it was around that time that these heart palpitations began to surface.

Main Points: Heart palpitations and blurred vision can be concerning symptoms, especially when they occur together. Your recent experiences, the potential link to caffeine, and manageable stress might play a role. While it’s important that you plan to seek medical advice, there are some immediate steps you can take to help assess the situation.
Explanation
Heart palpitations, which feel like your heart is racing, fluttering, or pounding, can be caused by several factors—including anxiety, caffeine intake, certain medications (like Olanzapine), dehydration, or even stress. Blurred vision can sometimes accompany palpitations due to changes in blood pressure or reduced blood flow, especially if the episodes happen after consuming stimulants like energy drinks.
Given that you’ve recently given up smoking and maintain a balanced lifestyle, it’s encouraging that you are aware of the potential triggers. However, stress and consumption of substances such as caffeine can contribute to these sensations.
Next Steps
-
Monitor Your Symptoms: Keep a log of your palpitations and blurred vision episodes. Note the time they occur, any accompanying symptoms, what you were doing beforehand, and any substances (like caffeine) consumed prior.
-
Reduce Caffeine Intake: Since your most recent episode followed the consumption of an energy drink, consider cutting back on caffeine to see if your symptoms improve. Pay attention to other sources of caffeine in your diet as well.
-
Stay Hydrated: Ensure you are drinking enough water daily, especially if you are consuming caffeinated beverages.
-
Manage Stress: Engage in relaxation techniques such as deep breathing, meditation, or light exercise like yoga to help mitigate stress, which may help reduce episodes of palpitations.
-
Avoid Stimulants: Besides caffeine, be cautious with other stimulants and any other new medications or supplements you might be considering.
-
Prepare for Your Appointment: When you see your doctor, share your symptom diary and discuss any patterns or triggers you notice. This information will be valuable for evaluation.
If you experience severe symptoms like fainting, chest discomfort, prolonged blurred vision, or increased anxiety, seek medical attention immediately.
While it's understandably concerning to have these symptoms, taking proactive steps can help you manage your anxiety and gather useful information for your healthcare provider. Let me know if you need further clarification or support!

Sudden Weakness and Numbness in Hand
I’m a 22-year-old woman diagnosed with lupus, essential tremor, and chronic migraines. My daily medication includes 120 mg of propranolol, and I use triptans as necessary. Recently, while attempting to open a coke bottle, I felt a clicking sensation in my wrist, followed by an abrupt loss of sensation in my hand. Since that moment, I have experienced persistent tingling, and my grip strength has significantly diminished. It seems like it might be related to carpal tunnel syndrome, a condition I wasn't previously aware I had. However, I do have a history of bilateral cubital tunnel syndrome and sciatica, so unexpected issues aren't unfamiliar to me. Since my ability to use my hand is crucial for my job, I’m seeking advice on steps I can take to restore sensation before returning to work in a few days. Any suggestions would be greatly appreciated!
Feeling Overlooked by Medical Professionals—Should I Advocate More for Myself?
I’m unsure if I’m posting in the right subreddit; please let me know if this isn’t the place for this discussion. I am a 15-year-old assigned female at birth, 165 cm tall and approximately 65 kg. For the past three years, I have experienced episodes where I collapse when standing. Initially, I faced dizziness that varied in severity before these episodes began. The intensity of my collapses ranges from simply falling to momentarily losing my vision—though my sight typically returns within about a minute. At times, I find myself unable to stand for 15 minutes, with my longest episode lasting around 30 minutes. When this issue first arose, I had mild dizzy spells, which both my physician and I attributed to my very heavy menstrual cycles. I was prescribed medication intended to reduce my menstrual flow (though I cannot recall the specific name, this was about four years ago), but it had little effect. Over time, my condition has worsened. The most definitive diagnosis I’ve received is a mild iron deficiency—something I learned in mid-2023 that has been reiterated at subsequent visits. The frequency of my collapses varies; there are months with only one incident, while in other weeks, it occurs every day. At my latest medical appointment, two weeks ago, my doctor suggested the issue stemmed from my menstrual cycle. I’ve been using Lucrin, a hormone blocker, for more than two years now. When I mentioned this, my doctor told me I simply needed more time for my body to rebuild its blood supply post-menstruation. I find this hard to accept, given the duration I’ve been on Lucrin. She also dismissed my concerns by stating that this is a frequent issue among young women and that I would eventually outgrow it. However, I have yet to meet anyone who experiences such frequent collapses as I do. Here are some additional details that might be relevant: - During more severe episodes, I sometimes experience difficulties speaking, including slurred speech or stuttering. - I can always sense my heartbeat in my head. - My heart rate increases significantly. - Depending on the severity of the collapse, I often feel disoriented afterward. Occasionally, I struggle to think clearly, which sometimes coincides with a temporary inability to move; though I don’t think this is directly related. - I reside in New Zealand. I apologize if my message comes off as a bit rant-like! It’s currently 2 AM, and I’m quite fatigued.
Concerns About Unexplained Body Odor
Demographic Information: Female, height 5'8", weight 185 lbs, with a past medical background including prediabetes, which has now been reversed; my A1C level stands at 5.2, and this has been consistent for the past six months. My husband and I have been in a committed relationship for a year now. I want to start by emphasizing my dedication to personal hygiene—I shower twice daily and consistently apply deodorant and perfume. However, earlier this year, my husband unexpectedly mentioned that I sometimes emanate a peculiar scent. This smell isn't constant. Initially, we speculated that certain foods, like cassava chips or chickpeas, might be the cause. However, I've also eaten meals consisting of olive oil and bread without any noticeable change; the smell still persisted. Even after thoroughly washing and brushing my teeth, he insists that the odor originates not from my breath but rather from my body. I'm at a loss trying to find answers, as no one has ever remarked on my odor before. When I ask my husband for a description, he struggles to articulate it. I’m reaching out for any professional opinions on this matter. I have an appointment with my nurse practitioner on July 15th to get further insight. I’ve come across alarming accounts of people detecting illnesses like cancer through odor, and it genuinely frightens me. Additionally, I can confirm that my clothing isn’t the source of the issue.
