Concern Over Low Iron Levels at Age 35
At the age of 35, I find myself reflecting on my health, particularly regarding my iron levels. I have struggled with being overweight and occasionally face gastrointestinal problems, including some rectal bleeding that presents as spots on toilet paper. Since 2014, I've donated blood 30 times, a practice I never considered problematic until recently. During my latest annual check-up and Complete Blood Count (CBC), several of my levels came back lower than expected: my hemoglobin (HGB) was 13.4, mean corpuscular volume (MCV) was 79.5, mean corpuscular hemoglobin (MCH) measured at 24.7, the mean corpuscular hemoglobin concentration (MCHC) was 31.1, and the red cell distribution width (RDW) was at 14.9. I later realized that I had similar low values for MCV (77.7) and MCH (25.5) during my previous year’s tests. Additionally, I had donated blood twice in the four months before my latest CBC and three times in the six months leading up to last year's test. Interestingly, my 2022 results were normal, aside from a low MCH of 26.5 back in 2019. A review of my past data shows that in 2013, when I was 24, my hemoglobin was at 14.7, MCV was at 84.1, MCH was 27.6, MCHC was 32.8, and RDW was 14.6. My doctor initially dismissed my low results, but a physician assistant encouraged further evaluation. The iron panel indicated an iron level of 55, total iron-binding capacity (TIBC) of 427, iron saturation of 13, and transferrin of 305. Despite my concerns (which I now realize may have been unfounded), I chose to focus on improving my diet, considering my weight. After two months, I returned on February 25, and although my results showed slight improvements — HGB at 13.7, MCV at 80.3, MCH at 25.4 (still low), MCHC at 31.6, and an RDW of 15.9 (which is now elevated) — I am left pondering my situation. The PA seemed pleased with the progress, yet I can't help but obsess over these findings. My numbers often sit at the lower end of the normal spectrum, and I wonder if this is typical. Do my frequent blood donations have an impact on these results? How alarmed should I be about my current state? I appreciate any thoughts on this matter.

Your concerns about your iron levels and the potential impact of blood donation on your health are valid and deserve attention. It seems you've been experiencing some fluctuations in your blood work, which can be stressful. Let's break down your situation and look at some actionable steps.
Summary of Findings
- Your iron panel shows low iron levels and low iron saturation, which can indicate iron deficiency.
- Frequent blood donations could contribute to your low iron levels since every donation removes iron from your body.
- Gastrointestinal issues, including occasional rectal bleeding, raise concern and could further complicate iron absorption.
Understanding Your Results
- Low Hemoglobin (HGB), Mean Corpuscular Volume (MCV), and Mean Corpuscular Hemoglobin (MCH): These values suggest that the red blood cells may not be carrying enough oxygen, often seen in iron deficiency anemia.
- Iron Metrics: Your iron and iron saturation are indeed low. A TIBC reading that is high indicates that your body is trying to make more iron-binding proteins because it lacks enough iron.
Next Steps
-
Dietary Changes: Focus on increasing your iron intake through food. Include:
- Heme Iron Sources: Lean meats, seafood, and poultry (these are better absorbed).
- Non-Heme Iron Sources: Beans, lentils, tofu, fortified cereals, and dark leafy greens (consider pairing with vitamin C-rich foods like oranges or bell peppers to enhance absorption).
-
Monitor Gastrointestinal Symptoms: Since you have rectal bleeding, it's crucial to monitor this closely. Document any frequency, color, and quantity of blood to discuss with a health professional. Addressing this may be critical for ensuring better iron absorption.
-
Limit Blood Donations: While donating blood is commendable, consider taking a break or reducing the frequency, especially if you are experiencing low iron levels. Discuss your donation frequency with a healthcare provider to align it with your health needs.
-
Supplements: Speak with a healthcare provider about potentially starting iron supplements, especially if dietary changes do not improve your iron levels or if the gastrointestinal bleeding is confirmed as a concern.
-
Regular Follow-Up: Schedule regular check-ups to monitor your blood work. Tracking your iron levels and overall blood health can help you notice trends and initiate changes early.
Be Reassured
While it’s natural to worry about these findings, many individuals manage low iron effectively with lifestyle adjustments and monitoring. Your proactive approach shows you are taking your health seriously, which is a positive step. Continue to advocate for yourself in discussions with your healthcare team, especially regarding any new or worsening symptoms you experience. If you feel your concerns are not being addressed, don't hesitate to seek a second opinion.

Managing Early Appendicitis: Antibiotics vs. Surgery
I’m a 21-year-old who recently had a CT scan revealing mild inflammation in my appendix and lymph nodes. My doctor informed me that surgery might not be necessary if the antibiotics effectively alleviate my discomfort by tomorrow. However, I can’t shake my fears about a potential recurrence of the inflammation. The thought of going through a post-surgery recovery terrifies me, so I really want to steer clear of that option. Has anyone opted for antibiotics rather than surgical intervention? What was your experience like?
Severe Abdominal Discomfort
An 18-year-old male, with no history of smoking or current medications, finds himself at home, surrounded by his sleeping family. He stands approximately 5 feet 11 inches tall and weighs around 220 pounds. Lately, he has been experiencing persistent discomfort in the lower left side of his abdomen.

Concerns Over My Partner's Persistent Pain and Resistance to Seek Medical Help
I’m facing a worrying situation with my partner, a 40-year-old man who stands 6 feet 1 inch tall and weighs approximately 19 stone. Here's a brief overview of his medical background: Twenty years ago, he experienced two instances of deep vein thrombosis (DVT) in his left shoulder. Following the second incident, doctors discovered an abnormal growth of a rib that was pressing against a vein, which was the cause of those DVTs. More recently, he dealt with a blood clot in his calf last year. Fortunately, that was successfully treated, and he returned to his normal health. Although he was advised to continue taking apixaban for the long term, he has, unfortunately, chosen not to follow through with this guidance. He also has a history of elevated blood pressure. For the past couple of days, he has been experiencing two concerning symptoms that emerged simultaneously: a persistent cough with no accompanying cold or flu signs, and a severe pain located on the right side of his torso. He describes this discomfort as being mostly in his stomach yet extending slightly to his back. I would pinpoint the troubled area as the lower part of his ribs along the side of his body. It's unusual for him to express discomfort or complain about his health, so his recent grievances signal to me that the pain is likely quite significant. Despite my repeated suggestions for him to visit a doctor, he insists that he may have simply pulled a muscle. To manage the pain, he's been applying an ibuprofen cream (voltarol) and taking naproxen, but neither seems to provide relief. What might be the underlying issue here? I hope that some medical professionals who see this post can offer their insights, which might persuade him to consider making a doctor’s appointment. I’m open to providing any additional information you might require for a more informed perspective. Thank you for your help!
Experiencing Unusual Sensitivity to Paracetamol
Hello, Reddit community! I'm a newcomer here, so please bear with me as I navigate this platform as well as the rules. I appreciate your understanding regarding my writing skills. I find myself in a situation that lacks sufficient information online, and I'm reaching out for insights from others. Currently, I have reasons to believe that I might be experiencing a unique sensitivity to paracetamol, and I’d like to share my timeline regarding this matter. Throughout my life, I generally had no issues with paracetamol. I used various brands multiple times and felt fine. However, starting in the fourth grade, I began to experience difficulties with it. My initial problems were respiratory-related, but soon they also affected my gastrointestinal system. I haven't had any formal testing yet, but I can safely use other pain relievers like NSAIDs without any adverse effects. Initially, I tolerated paracetamol relatively well; my early symptoms seemed like common side effects. Unfortunately, it escalated to severe reactions, including vomiting, tightening of the throat, blood in my mucus, and shortness of breath. In my confusion, I thought limiting my dosage could help, which it did temporarily, but eventually even the reduced amounts failed to be effective. I experimented with syrup formulations that contain less paracetamol or where it isn't the primary ingredient, and found those to be more manageable. Recently, however, even those have become problematic, making it necessary for me to seek alternatives to paracetamol, as it has become increasingly intolerable. Through my research, I discovered that such reactions often stem from cross-sensitivity to other medications or from preexisting respiratory conditions. I lack a history of asthma or other respiratory issues, so I’m inclined to dismiss that possibility, although I remain uncertain. Moreover, I have no known allergies, which adds to my confusion since my reactions only occur with this one particular medication while all others seem fine. It is difficult for me to process this change, especially since I used to have no issues with paracetamol. It is widely available and generally considered safe, so I struggle to understand the source of my suffering. Many people insist that these reactions are normal side effects, leading me to question whether I am overreacting. The immediacy of my reactions intensifies my concern; I don’t even need to swallow the medication completely before I notice my throat constricting, increased mucus production, and shortly thereafter, some blood in my mucus along with persistent coughing. This pattern has become consistent, whereas it used to depend on the dosage. Now, regardless of how much I take, the same symptoms occur. I’ve tried to dismiss it, not wanting to worry my parents or seek medical attention for a dosage safety test, fearing I’ve already pushed my body too much. However, I am considering discussing my concerns with my mother since she is increasingly worried about my use of this medication. I’m not seeking a diagnosis or medical advice—I understand I should probably consult a professional. I’m just interested in knowing if anyone else has faced similar experiences, as the confusion grows. What I once assumed were normal side effects now seem to signify something more concerning.
