Potential Sensitivity to Indoor CO2 Levels?

6/26/2025, 1:10:26 AMMale25-34

To provide some context: We have recently settled into a home that uses natural gas, marking our first experience with it. My son, who is 19 years old and stands at 6'1" with a BMI around 36, generally enjoys good health aside from a somewhat inactive lifestyle. After a few months in our new place, he began expressing discomfort, particularly in his arms—mainly at the shoulders and around the elbows and wrists. He also occasionally reports feeling lightheaded or short of breath, coupled with mild chest pressure. A medical examination resulted in normal tests, leaving us without clear answers. Observing a trend, I noticed that his discomfort tends to arise shortly after we've cooked meals. As a dedicated reef aquarium hobbyist, I've also struggled to keep the pH levels stable in my main tank. This prompted me to purchase a CO2 monitor, which revealed that cooking incidents raise indoor CO2 levels to approximately 2500 ppm, with a minimal baseline of 1500 ppm when we're not cooking. Remarkably, he reports improvement within about an hour of ventilating the space to bring CO2 levels below 1500 ppm. I haven’t shared my observations with him to avoid any psychosomatic implications. Interestingly, he appears to be the only individual in our household exhibiting such sensitivity. I am keen to hear from medical professionals if they have encountered similar cases and whether this might indicate a deeper medical issue. It’s also worth noting that during these episodes—with elevated CO2—his oxygen saturation remains normal at 98-99%, and his blood pressure is generally around 117/75. He has no history of substance usage or alcohol consumption. I also have a recent ECG from him which could provide further insights, though I'm not including any links or images for clarity.

It sounds like you are observing a concerning pattern with your son's symptoms potentially linked to elevated indoor CO2 levels, especially given the context of his discomfort after cooking. To summarize the key points:

  1. Symptoms: Your son experiences discomfort in his arms and sensations of lightheadedness or mild chest pressure, particularly after cooking.
  2. CO2 Levels: High indoor CO2 levels, especially post-cooking, could be causing these symptoms.
  3. Immediate Improvements: His symptoms improve quickly with ventilation when CO2 levels decrease.

Explanation

Carbon dioxide (CO2) at elevated levels can cause symptoms like lightheadedness, headaches, and an overall feeling of discomfort. While your son's oxygen levels remain normal, the sudden increase in CO2 from gas cooking might be impacting him in a way that not everyone experiences. His height and BMI indicate he may lead a relatively inactive lifestyle, which can also contribute to his symptoms, especially if he has any underlying fitness concerns.

Next Steps

  1. Increase Ventilation: Immediately focus on improving ventilation in your home when cooking. This can involve using exhaust fans, opening windows, or using air purifiers to help manage CO2 levels better.
  2. Monitor CO2 Levels: Continue using your CO2 monitor to track levels regularly, particularly after cooking. Aim to keep CO2 levels below 1000 ppm when possible and below 1500 ppm as a long-term goal.
  3. Document Symptoms: Keep a symptom diary for your son to log when the discomfort occurs and its severity. Note any correlation with CO2 spikes.
  4. Lifestyle Adjustments: Encourage your son to engage in light physical activity. This could help improve his overall well-being and progressive fitness.
  5. Explore Cooking Practices: Consider alternative cooking methods that produce less CO2, such as electric stoves, or ensure simultaneous use of ventilation systems while cooking.

If symptoms persist despite these changes, or if you notice any worsening conditions, consider seeking further medical evaluation focusing on environmental factors. It's beneficial that you've tracked these changes; they can provide insights during medical discussions. Your observations are important, and addressing environmental triggers is a practical first step in managing his condition.

Battling Chronic Nausea and Vomiting for Over Two Years

For the past two years, I (age 26, female) have been enduring an incredibly challenging health situation. I experience intense nausea daily and find myself vomiting numerous times, with almost nothing providing relief. To provide some background, I’m from West Texas and I currently weigh around 190 pounds, standing at 5’7”. Initially, my weight was about 211 pounds when these symptoms began, and it fluctuates frequently between 190 and 225 pounds. I engage in vaping and consume THC. Previously diagnosed with hypothyroidism, my condition seemingly resolved, according to my healthcare providers. Additionally, I have polycystic ovarian syndrome (PCOS). I have consistently faced irregular bowel movements, with stools that are loose and sometimes appear to have mucus. Compounding my struggles, I've also suffered from migraines. I have had an IUD for over five years, experiencing two insertions of the Kyleena device. In December 2022, my battle with health took a severe turn when I was diagnosed with stage 4 Hodgkin’s Lymphoma, requiring chemotherapy treatment, specifically AVBD (Apologies for not recalling the exact medication names). By July 2023, I had fortunately achieved remission. However, after reaching remission, my vomiting worsened, transforming from primarily white foam to a mixture of 80% bile, any food I attempt to consume, and still white foam. This intense vomiting, accompanied by significant pain in my upper back, escalated to more than eight episodes daily by November 2023. At that time, THC seemed to be the only avenue for me to retain any food. During this tumultuous period, I consulted various doctors who, after confirming I wasn’t pregnant, attributed my symptoms to Cannabinoid Hyperemesis Syndrome (CHS). Immediately, I ceased THC consumption for over six months, yet the vomiting continued unabated. Each time, doctors would prescribe ondansetron, regardless of my claims that it provided no relief. I experimented with various diets recommended by medical professionals, but there were no improvements in my condition. Eventually, I obtained a referral to a gastroenterologist who intended to perform an endoscopy. However, the procedure was prohibitively expensive even with insurance, and thus was never conducted. This doctor also ordered blood tests to rule out several gastrointestinal disorders, such as Crohn's disease, Irritable Bowel Syndrome (IBS), and gluten sensitivity, but all results came back normal. Afterward, I had another appointment with a different gastroenterologist, but the doctor failed to meet with me. Instead, a nurse informed me that the doctor had merely recommended promethazine without conducting any tests or scheduling further visits. When I mentioned the possibility of gallbladder issues, the doctor laughed dismissively at my suggestion. Discussing my situation with my oncologist, he suggested that my heightened sensitivity to food odors stemmed from my chemotherapy experiences while I was working in fast food. While food smells indeed affect me, I'm primarily triggered by medical scents such as rubbing alcohol and cleaning agents. This ongoing ordeal has been overwhelmingly distressing. I now experience episodes of vomiting accompanied by bright red blood, presumably due to a throat tear. When I first encountered this troubling symptom, I consulted a doctor who appeared unfazed and prescribed a promethazine suppository, which does help but makes me extremely drowsy. My nausea persists nearly around the clock, often feeling as if there’s a heaviness in the upper part of my abdomen. I frequent urgent care facilities when my symptoms intensify, only to be met with minimal assistance since this is a chronic issue. Currently, I lack a primary care physician. Whenever I sought one, I encountered skepticism regarding my condition, with some healthcare professionals implying that I was exaggerating my symptoms. Though many physicians who do take my situation seriously seem baffled, I've lost count of the diverse medical experts I've consulted about these ongoing issues. If anyone has insight or suggestions, I would genuinely appreciate it. I can share my latest bloodwork results if that would be helpful—just let me know!

Strange Stomach Sensation Leading to Waking Up

Greetings. I'm a 36-year-old male, standing at 172 centimeters and weighing 90 kilograms. I don't take any medications, nor do I smoke. I've been living with diastasis recti for several years now, and I may also have irritable bowel syndrome (IBS). Additionally, I deal with fatty liver and kidney stones, though I assume these last two conditions are not related to my current concern. Occasionally, I experience a peculiar sensation that jolts me awake; it feels like a quick pulsing in my stomach. I’ve noticed it tends to affect the left side when I’m lying on my left side and the right side when on my right. Remarkably, it can occur even when I’m on my back. This strange feeling often escalates into a surge that fully rouses me. Alongside this, I sometimes feel prickling sensations throughout my body and fleeting lightheadedness. When this sensation disturbs my sleep while I’m turned to my side, shifting onto my back or the opposite side might alleviate it, but not always. In instances where I awaken while lying on my back, I discovered that gently pressing my hands on either side of my stomach can help, as can rising to a sitting or standing position. However, during my last two episodes—one a couple of weeks ago and another tonight—those techniques weren’t effective right away, which made me feel a bit anxious, prompting me to seek advice. Does anyone have insight into what might be going on? By the way, I’ve undergone routine ultrasound examinations of my abdomen by two different physicians during check-ups, both of whom assured me that everything appears normal, including my abdominal aorta and internal organs. They didn’t identify any issues at that time.

Understanding Tuberculosis Exposure Risk

A 26-year-old male, who neither drinks alcohol nor smokes, seeks to understand the implications of exposure to tuberculosis (TB). As an anesthesia technician, I became concerned after I encountered a TB-positive patient about a month ago. I had to enter the patient’s room several times to perform blood gas tests. On my first entry, I mistakenly wore my N95 mask incorrectly due to the hectic nature of attending to multiple rooms. From my research, it appears that TB is quite transmissible; direct exposure can pose a serious risk of infection. Transmission usually requires prolonged contact with an infected individual, particularly in a close or face-to-face setting. In this case, the patient was lying face down and appeared to be sleeping when I entered. I have already undergone testing for TB, but I am eager to deepen my understanding of the risks involved in these situations.

24M | Unexplained Fainting Incident

**Note:** I previously shared this story, but it was inexplicably removed. I’m a 24-year-old male without any medical diagnosis or prescription medications. While I do consume alcohol occasionally, I hadn’t been drinking before this happened. Around 3 a.m., I got up from bed to use the restroom. As soon as I began to urinate, I suddenly felt a wave of dizziness. The next moment I was aware of was regaining consciousness in the bathtub, startled awake by the sensation of something dripping on me—only to discover it was my own blood. This was my first experience with fainting. When I came to, confusion set in. I was disoriented and couldn’t comprehend why I was being dripped on while in what I thought was my “bed.” Strangely, I also imagined that I was lying on a collection of marbles (which I actually don’t own)—this turned out to be the shattered glass of my shower door lying around me. I’m uncertain whether I lost consciousness first and then fell, or if the fall caused my brief blackout. It took me a few moments to understand why I was in the bathroom at all. I’m not sure how long I was out; I only remember it was around 3 in the morning when I initially got up, and about the same time when I regained consciousness. I dialed 911, and the ambulance arrived promptly. They checked my vitals, performed an EKG and measured my blood sugar, finding nothing unusual. At the emergency room, they repeated the vital checks, conducted a CT scan, drew blood, and took x-rays—yet still no abnormalities were detected. I had several cuts on my face and left arm (curiously, this is the arm that would have been turned away from the door), along with bruising around my ribs. Since the incident, I’ve been suffering from headaches and pain in my ribs. I received stitches on both my face and arm. The nurse suggested I could have stronger pain relief, but I opted for just Toradol. They eventually discharged me, stating, "We’re unsure what caused this, but return if it happens again." What might have triggered such an incident? How can I safeguard against it reoccurring if they remain uncertain about the cause?

Healing Progress Post-GBS: Toe Concerns

I am a 28-year-old male, measuring 5 feet 10 inches and weighing 131 pounds. My current medications include Fomadatine and Zyrtec, prescribed due to my ongoing battle with Chronic Gastritis and SIBO. I maintain a healthy lifestyle, abstaining from both smoking and alcohol. My health concern revolves around the toe adjacent to my pinky toe on my left foot, as well as my pinky toe on the right foot. Since August of last year, I have been on the mend from Guillain Barre Syndrome. Recently, I've noticed that at night, the skin on my feet tends to turn a reddish pink, although this usually improves after I walk around. However, two of my toes have remained red, with one appearing slightly swollen. Generally, my pinky toes are quite thick, but the condition of my left foot's toe is worrisome for me. It seems that I'm unable to upload an image to illustrate my issue.
