Can I Really Detect Illness by Smell?

3/18/2025, 9:50:16 PMMale25-34

At 23 years old and weighing 112 pounds, I've experienced something unique for as long as I can recall. As I've grown, I've noticed an unusual ability: I can detect when someone is unwell or on the verge of falling sick, simply through smell. Although I find it challenging to pinpoint specific scents linked to particular illnesses, I have observed that respiratory infections emit a distinctly sour aroma that reminds me a bit of the smell of dirty socks. My brother is skeptical about this perception, questioning if it's plausible. Could I be sensing something similar to how dogs do? Or is it possible that I am merely connecting their visible symptoms to an unrecognized scent?

It's fascinating that you've noticed how your sense of smell can alert you to when others may be feeling unwell. While this ability isn't commonly discussed, there are some insights from science that may help clarify your experiences.

Main Points

  • The human sense of smell is indeed powerful, and some research suggests that specific odors can be linked to illnesses.
  • While you might not be able to pinpoint exact scents for each condition, your observations may align with scientific findings that show certain illnesses can produce unique volatile compounds that humans can detect.

Explanation

  1. Human Olfactory Sensitivity: Humans have a more developed sense of smell than is often recognized. Certain diseases can cause metabolic changes that produce distinctive odors. For example, infections may alter skin and breath odors due to the breakdown of proteins or changes in bacterial flora.

  2. Animal Comparison: Animals like dogs have a far superior sense of smell and can detect subtle changes that humans often cannot. However, some research indicates that humans may still be capable of picking up on specific illness-related odors to an extent.

  3. Psychological Connections: It's also possible that your previous observations shape your awareness. When you notice someone acting ill, you might become more attuned to undetectable changes, making the association stronger in your mind.

Next Steps

  • Keep Observing: Pay attention to the specific scenarios where you detect these smells. Keeping notes can help you identify patterns related to illnesses or symptoms.
  • Research: Look into studies regarding olfactory detection of illness. This might provide you with more context about the science behind your ability.
  • Discuss with Friends/Family: Share your observations with those close to you and ask if they’ve noticed any particular changes when they are sick. Their input might give you further insights.
  • Stay Curious: Consider exploring this interest further, perhaps through courses or articles on sensory perception or even the psychology of smell.

This kind of exploration can be both intriguing and enrich your understanding of health and human senses. I'm here if you have more questions or need further information!

Tragic Situation Surrounding a Benadryl Overdose

Hello everyone. I’m reaching out because my younger sister, who was just 14 years old, tragically ended her life last night using Benadryl. I’m here seeking insight into her situation, and while I don’t need condolences, I appreciate any expressions of sympathy that may come my way. What I truly seek is raw, unfiltered information about what she may have experienced. Details: (I lack medical knowledge, so this information may not be crucial) - Female, age 14 - Height approximately 5'5" (give or take) and weight around 105-115 pounds (this is an educated estimate) - Took between 160-180 tablets, totaling around 4-4.5 grams (this estimate is based on my recent purchase of the bottle and her typical usage for sleep) My questions are as follows: (Feel free to share any other thoughts as well) How much time did she have after ingesting the medication? What might her last moments have been like? Was her passing calm, or was it filled with hallucinations or confusion? Did she experience seizures, or did she simply fall asleep? These are the difficult questions that I find hard to research myself. I hope that this discussion can provide clarity for anyone who might find themselves in a similar situation someday. I’m immensely grateful for any help in advance. As I post this, I’ ll be going to bed soon and may not respond to comments unless they hold significant questions related to my inquiries, though I might reconsider that later on.

Concerns About Measles Exposure After Outbreak at Work

We have not experienced any symptoms, and both of us received our vaccinations during childhood. Recently, one of our coworkers was identified as the initial case of measles within the state and has since been hospitalized. The workplace is a smaller manufacturing facility, employing around 30 people, many of whom are unvaccinated. Given this situation, do we need to take any specific actions? Is it still possible for us to transmit the virus despite being vaccinated? We are uncertain about the necessary safety measures to adopt. Our employer hasn't communicated anything regarding the outbreak; we only learned about it when we saw our workplace mentioned in the news.

Is a Red Spotted Uvula and Fever Enough to Visit the Clinic?

I am a 30-year-old woman, standing at 5'2" and weighing 280 lbs. I smoke marijuana but do not use any nicotine or vaping products. On Wednesday morning, I woke up experiencing a painful throat. The discomfort is more pronounced when I first wake up but tends to ease up later in the day. I’ve been experiencing minimal coughing, some post-nasal drip, and a fever fluctuating between 100.8°F and 101.4°F, alongside significant fatigue. Today, I also developed headaches. I suspect that my lymph nodes might be swollen, but I'm not a health expert, so I can't be certain. I have been checking my temperature rectally, as my mother mentioned that I typically don't exhibit typical fever symptoms outwardly. Is it advisable for me to see a doctor? I worry about taking up a physician's time if this is just a viral infection. No one else at home or any of my coworkers are showing symptoms of illness.

Persistent Low-Grade Fever: Seeking Insights

Greetings everyone, I am reaching out in hopes that someone may provide insight into my situation. I am a 41-year-old female, weighing 185 pounds and standing 5 feet 2 inches tall. My current medications include Trintellix, prescribed for my depression, a low-dose statin for cholesterol management, and a multivitamin. Eight months ago, I experienced a challenging second pregnancy, which involved gestational diabetes and postpartum preeclampsia; however, those concerns are now resolved, and aside from this issue, my overall health remains stable. For the past two months, I've been experiencing a daily temperature fluctuating from 99°F to 100.2°F, which is unusual for me as my normal body temperature is typically around 98.2°F. Recently, I've had multiple atypical infections and tend to catch various illnesses from my son, who is in daycare. It’s noteworthy that I tend to contract infections even when my husband remains unaffected. In the last six months, I've required antibiotics on four occasions for ear infections, including one for a dental infection and several associated with the onset of these persistent fevers, aimed at addressing a possible general infection. Blood tests examining autoimmune markers, thyroid function, iron levels, and other general indicators have all returned normal results, with the exception of Epstein Barr, which confirmed I have been exposed and developed considerable antibodies. Dental infections have been ruled out as well. Apart from frequent illnesses and recurring ear infections, I have no additional symptoms to report. With my postpartum period at eight months now, my next steps involve consulting with specialists in infectious diseases and ear, nose, and throat (ENT) worries. I am open to any suggestions or thoughts on potential avenues for further investigation regarding my ongoing fever. Thank you for your help!

Managing Fever with NAFLD

At 31 years old, I've been dealing with some health challenges. In September, I discovered I had non-alcoholic fatty liver disease (NAFLD) due to abnormal enzyme levels revealed in an ultrasound. Although my latest results show a decrease, my enzyme levels remain somewhat elevated, with a moderate accumulation of fat noted. My doctor advised against using acetaminophen for pain relief. Interestingly, my father, who has a more severe case with significantly higher enzyme levels, was allowed to use acetaminophen but not ibuprofen. Since my diagnosis, I've avoided both medications. However, I am currently suffering from a cold accompanied by a fever of 100.2 degrees, which is quite uncomfortable. I reached out to my healthcare provider for advice, but since it's late at night, I probably won't receive a response until tomorrow. For context, I am on a treatment regimen that includes 20mg of Abilify and 50mg of Pristiq, and I do not consume alcohol. Today, I also took Sudafed PE twice to help with my symptoms.
