Seeking Insights on Blood Condition
Hello everyone, I could use some advice from a hematology specialist regarding my recent blood work and health history. I decided to share my situation after noticing a few similar cases discussed here. At 29 years old and having smoked for nearly a decade, I have consistently seen mild elevations in my hemoglobin and hematocrit levels spanning the last two years: - 2023: Hb 16.8 g/dL, HCT 49% - January 2025: Hb 17.2 g/dL, HCT 51% - June 2025: After undergoing a phlebotomy in February, my latest values were Hb 16.2 g/dL, HCT 48.3% - EPO level stands at 6.55, which falls within normal ranges. - MPN panel results came back negative for JAK2, CALR, and MPL mutations. - Iron studies have shown normal results, and counts for other blood components, like white blood cells and platelets, remain stable. - I do not have an enlarged spleen, nor am I experiencing any related symptoms. - Additionally, I don't take testosterone and haven’t been exposed to high altitudes. Three healthcare professionals I consulted suggested that my condition might be secondary polycythemia related to smoking. However, two others raised concerns about the possibility of early or undiagnosed polycythemia vera (PV), especially given my hemoglobin and hematocrit levels that exceed diagnostic cutoffs (Hb > 16.5 / HCT > 49) and my EPO being “inappropriately normal.” Given these factors, is it feasible that PV could still be a concern for me, or is it more likely that this is just secondary erythrocytosis induced by smoking?

It's understandable to be concerned about your blood work and what it might indicate about your health. Based on the details you've provided, it appears you are navigating a complex situation regarding your hemoglobin and hematocrit levels, guided by multiple healthcare professionals.
Main Points
- Your elevated hemoglobin and hematocrit levels might suggest secondary erythrocytosis due to smoking.
- The possibility of polycythemia vera (PV) could be considered, yet factors like negative mutation tests and normal EPO levels provide reassurance against this diagnosis.
Explanation
Your hemoglobin and hematocrit levels are indeed elevated, and while secondary polycythemia due to smoking is a strong possibility, PV is a consideration that can’t be completely ruled out. The fact that your EPO level is normal while your blood counts are elevated does suggest that your body might not be reacting in the typical way one would expect in cases of oxygen deprivation or other related conditions. Negative mutation tests for JAK2, CALR, and MPL further reduce the likelihood of PV as they indicate the absence of common genetic mutations usually associated with this condition.
Next Steps
- Monitor Blood Levels: Continue to track your hemoglobin and hematocrit levels, and maintain regular check-ups to catch any significant changes early.
- Lifestyle Modifications:
- Quit Smoking: If you haven't already, consider quitting smoking. This is crucial as it may improve your blood values and overall health.
- Stay Hydrated: Maintain adequate hydration, as dehydration can also affect blood concentration and lead to elevated levels.
- Maintain Communication: Discuss with your healthcare provider regular follow-ups and possibly further testing that could rule in or rule out other causes if your levels remain elevated or worsen.
- Lifestyle Factors: Engage in moderate physical activity and follow a balanced diet, as these can also positively influence your blood health.
If any new symptoms arise or if you have further concerns, don’t hesitate to advocate for more investigation into your situation. Your health and peace of mind are important, so continuous dialogue with your healthcare providers is key. Let me know if you have more questions or need additional insights!

Persistent Itchy Rash Surrounding the Lips and Moustache Region
I am a 21-year-old male residing in India. Approximately three months ago, I began experiencing a bothersome, red rash on the area around my upper lip and moustache. Initially, I consulted a dermatologist who recommended the following treatments: - Hydrocortisone ointment - An antifungal cream - Chaptex Lip Care Balm Although there was some initial improvement, the rash has recently resurfaced, bringing with it severe itching, redness, and occasional swelling with fluid discharge from the infected areas. The regions around my lips and moustache seem to be the most affected. While there are no signs of blisters or pus, the inflamed skin often appears red and can weep, particularly after scratching. I have not altered my skincare routine or shaving products in any way.
Seeking Advice on Tailbone Injury from X-Ray

Concerns About a Tick-Borne Illness: Steps to Take Before Medical Consultation
I’m a 30-year-old male weighing 175 pounds, and I generally maintain a good state of health without any medications. Residing in Southeast Missouri exposes me to various tick-related ailments. Over the years, I’ve frequently encountered tick bites, developing a routine of checking for them nightly. On average, I find a couple attached to my skin a few times a year. My usual method involves removing them and applying antibiotic ointment along with a bandage for a short period, and I usually move on without issues. However, four days ago, I noticed a bothersome itch on the top of my foot by my pinky toe. At first, it was just a slight annoyance, so I didn’t pay much attention. The next day, the irritation escalated; the area became red and intensely itchy, resembling a rash from poison ivy or oak. I responded by applying hydrocortisone cream. Unfortunately, this morning, the discomfort increased, and now the rash has spread around the bottom of my foot, nestled between my pinky toe and the one adjacent. I was initially perplexed about how I might acquire a rash from a plant, given that I hadn’t ventured into wooded areas recently—my activities were limited to my yard and surroundings. Notably, I’ve never experienced a reaction to poison ivy before; the last time I handled it, about five years prior, I wasn’t even aware of its presence when I removed it from a tree. My suspicions now lean towards a possible insect bite, as I recalled discovering a small seed tick between my toes around a month ago, quite close to where the current irritation is. I plan to visit either urgent care or the emergency room as soon as I finish work today to seek professional advice. In the meantime, I would appreciate any recommendations on how to prepare for my visit. What specific questions should I consider asking the healthcare provider regarding my symptoms? Any insights would be helpful before my consultation begins.
Concerns Regarding Rabies Vaccination After Bat Encounter
Hello everyone! I'm currently residing in the UK and I recently returned from a holiday in France where I had a rather unexpected encounter with a bat. The creature flew directly past me, brushing against my ear. Thankfully, I did not sustain any visible injuries such as scratches, bites, or inflammation. After the incident, I consulted with a doctor while in France, who determined that there was no need for a rabies vaccination. I followed up with a doctor back in the UK who echoed that assessment, as I did not have any breaches in my skin. However, I’ve come across information suggesting that even minor, microscopic abrasions could potentially allow for the transmission of rabies. It's worth mentioning that the bat appeared to be acting normally, flying during twilight, and I simply happened to be in its flight path. I wonder if it's reasonable to seek further medical advice on this matter?
Elevated Growth Hormone Levels Yet Normal IGF-1
Height: 182 cm, Weight: 92 kg, Age: 25 Greetings everyone, I wanted to share my recent health experience. A few months back, I had to spend a night in the hospital due to significant dehydration. Following my discharge, I decided to request some blood tests for my personal peace of mind. In addition to the hydration-related tests, I specifically asked for growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels to be checked. The results revealed that my GH level was at 31 mIU/L, which is considerably above the normal range of less than 3.1 mIU/L. Conversely, my IGF-1 was measured at 41 nmol/L, falling within the standard range of 17 to 48 nmol/L. Since then, I’ve had my blood checked two additional times. A month ago, my serum growth hormone was recorded at 14 mIU/L, and just this week, it dropped slightly to 13 mIU/L. Does anyone have insights into why I might experience elevated growth hormone levels while still maintaining normal IGF-1 levels?
