Addressing Low Ferritin Levels in Runners: Effective Strategies
Greetings! I’m a 43-year-old female, standing at 5'7" and weighing 150 pounds, of Caucasian descent. As someone who frequently runs, I have been experiencing a persistent sense of fatigue. Recently, I had my iron levels checked, revealing that my ferritin sits at 14 ng/mL, which is considered low. The results showed my total iron at 67 mcg/dL, my iron binding capacity at 318 mcg/dL, and my saturation level at 21%. Additionally, my hemoglobin level is at 14.0 g/dL. Currently, I am not on any medications, nor do I consume alcohol, smoke, or use recreational drugs. I am curious if the reduced ferritin might be contributing to my ongoing fatigue. Also, it's worth mentioning that my MCV and MCH values have consistently appeared on the higher end of the normal range for quite some time. I have sought clarity on whether these high-normal readings impact my iron levels, but so far, I haven't received a conclusive answer. I am scheduled to consult with a functional health specialist in the near future, but I would love to gather insights on the most effective treatment strategies for my condition. Thank you!

Main Points: Low ferritin levels can contribute to fatigue, especially in runners. It’s essential to address the low ferritin with dietary changes and, if necessary, supplementation while monitoring your overall health.
Explanation: Ferritin is a protein that stores iron in your body, and low ferritin levels (like your level of 14 ng/mL) can indicate that your iron stores are depleted. This can indeed lead to symptoms like fatigue because iron is crucial for energy production and overall metabolic function. Your hemoglobin level is within the normal range, which suggests that while your body is still able to transport oxygen effectively, your iron stores are compromised.
The higher normal MCV (mean corpuscular volume) and MCH (mean corpuscular hemoglobin) might imply that your red blood cells are larger or contain more hemoglobin, but they do not necessarily directly influence your iron levels. However, it can reflect your body’s attempt to compensate for lower iron levels.
Next Steps:
-
Dietary Adjustments: Focus on increasing your iron intake through food. Include:
- Heme Iron Sources (more easily absorbed): Lean meats, poultry, and fish.
- Non-Heme Iron Sources: Lentils, beans, tofu, spinach, and fortified cereals.
- Vitamin C: Pair iron-rich foods with vitamin C sources (like citrus fruits, strawberries, or bell peppers) to enhance iron absorption.
-
Consider Iron Supplements: While you wait for your consultation with the specialist, you might want to consider an over-the-counter iron supplement (like ferrous sulfate) to help boost your levels. However, be cautious and follow dosage instructions carefully, as excess iron can cause side effects. It’s best to discuss this with your upcoming specialist.
-
Assess Hydration and Rest: As a runner, ensure you’re properly hydrating and getting adequate rest to help mitigate fatigue. Consider adjusting your training intensity if fatigue persists.
-
Monitor Symptoms: Keep a journal of your energy levels, dietary changes, and any new symptoms as you implement these strategies. This can help identify patterns and guide further discussions with your healthcare provider.
-
Scheduled Follow-Up: Follow up with your functional health specialist regarding your ferritin levels and overall strategy, including any necessary blood tests to monitor progress.
Feel free to ask if you need more specific dietary ideas or additional strategies! Your health and well-being are important, and taking these steps can help you feel more energized and perform better in your running.

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?

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!
Struggling with Bleeding and Pain Since Christmas
I'm a 27-year-old woman from the UK, and I've reached a point of exasperation. I'm reaching out because I hope someone can provide insight or guidance on what I should discuss with my doctors. Please excuse any grammar or spelling errors as I have dyslexia. I've been diagnosed with endometriosis and underwent surgery in 2022 for confirmation of that diagnosis. On December 15th, I had my birth control implant removed after nearly two years. During that period, I experienced severe menstrual cramps and PMS. My GP started me on Drospirenone 3mg and Estetrol 14.2mg COCP in October to alleviate these symptoms and suppress my periods, which provided some relief. Prior to this situation, I occasionally dealt with flare-ups that typically lasted a few days or up to a week. To help manage the discomfort, I have been prescribed Duloxetine at a dosage of 90mg. I had an ultrasound earlier this summer, and the results came back normal. Currently, I am awaiting an MRI. Last year, my smear test results were also clear. After the removal of my implant in December, I began bleeding on Christmas Eve. Initially, I could manage with just a panty liner, but over the next few weeks, the bleeding intensified, requiring the use of pads due to increased blood flow and blood clots. Given my history with endometriosis, pain isn't unfamiliar to me; my average pain level is around a 4, but it has recently escalated to 7 or 8. In the past couple of weeks, the discomfort has worsened. My job demands physical activity, and bending over now causes pain in my back and legs. Additionally, I experience discomfort when my bladder fills, and urination is painful, although it doesn't feel like a urinary tract infection. I've also been waking up at night to use the restroom. My doctor performed a urine dip test that showed no signs of infection, though there was blood in my urine, which he indicated was to be expected. Recently, my GP prescribed Tranexamic acid 500mg and Mefenamic acid 500mg, which helped with the blood clots, but I'm still experiencing bleeding and significant pain. I've been diligent about taking my medication, treating it like a strict regimen. I returned to the GP, who referred me for another ultrasound and advised me to go to A&E if the pain worsens. I've been resting as much as possible while still trying to maintain some level of activity, but it hasn't provided much relief. Any assistance or advice would be immensely appreciated! Thank you!
