Low Ferritin and Vitamin D Levels Despite Supplements?

4/21/2025, 9:10:26 PMMale25-34

A 30-year-old female presented without any significant medical issues and takes a prenatal vitamin only when she remembers to do so daily. The patient reported experiencing persistent hair loss that began in 2025, following COVID. Previously, she enjoyed thick hair that would often snap ponytails, but since the onset of COVID, her hair has been progressively thinning, particularly around the areas above her ears. During a visit to a dermatologist, concerns arose regarding a potential psoriasis condition on her knee, prompting the doctor to order laboratory tests, including ANA and EBV, both of which returned negative results. Analysis of her lab work revealed that while most values were within normal ranges, her ferritin level was recorded at 14, indicating a potential deficiency, and her vitamin D level was significantly high at 276. She has been taking a prenatal supplement for the last year containing 15 mcg of vitamin D and 27 mg of iron, both of which meet the daily value requirements. What advice can be provided for addressing these findings?

You’re experiencing low ferritin levels alongside high vitamin D levels, which can be concerning, especially given your hair loss. Let's break down these findings and outline actionable steps to improve your situation.

Main Points:

  1. Low Ferritin Level: Indicates potential iron deficiency, which can contribute to hair loss and other health issues.
  2. High Vitamin D Level: Suggests you may be taking in more vitamin D than your body needs, which might require adjustment.
  3. Hair Loss: Commonly linked to nutritional deficiencies, stress, or possible underlying conditions.

Explanation:

  • Ferritin is a protein that stores iron in your body. Low levels could lead to anemia and symptoms like fatigue and hair loss. Deficiency in iron is known to affect hair growth cycles.
  • Vitamin D is essential for overall health, but excessive levels can have adverse effects, including possibly causing calcium imbalance and other organ issues.
  • Hair Loss following COVID-19 could be due to various reasons including telogen effluvium, where hair falls out after stress or illness, or due to nutritional deficiencies, such as iron deficiency.

Next Steps:

  1. Increase Iron Intake:

    • Dietary Sources: Incorporate iron-rich foods into your meals, such as red meat, poultry, fish, lentils, beans, spinach, and fortified cereals. Pairing these with vitamin C-rich foods (like citrus fruits) can help improve iron absorption.
    • Consistent Supplementation: If you find dietary sources challenging to meet your needs, consider consistently taking an iron supplement (preferably in consultation with a healthcare provider to avoid over-supplementation).
  2. Monitor Vitamin D Intake:

    • Review Supplementation: Since your vitamin D levels are high, consider reducing the frequency or dosage of your prenatal vitamin, specifically looking at its vitamin D content. It may be helpful to stop taking additional vitamin D supplements for a while and reassess your levels in a few months, as high levels can pose risks.
    • Sun Exposure: Your body produces vitamin D when exposed to sunlight. Aim for about 15-30 minutes of sun exposure a few times a week without sunscreen (depending on skin type and local weather conditions) to naturally maintain vitamin D levels without excessive supplementation.
  3. Monitoring Hair Health:

    • Scalp Care: Maintain good hair and scalp hygiene and consider using gentle, nourishing hair products to promote a healthier scalp environment.
    • Stress Management: Since hair loss can be exacerbated by stress, consider engaging in activities that reduce stress such as yoga, meditation, or regular physical activity.
    • Track Progress: Keep a diary of your dietary intake and hair condition over the next few months, noting any changes in hair growth or loss patterns.
  4. Follow-Up:

    • Regularly check in with your healthcare provider about your iron and vitamin D levels, and consider further testing or evaluations if hair loss persists or worsens.

In conclusion, focusing on increasing your iron intake and adjusting your vitamin D supplementation should be your primary goals. If you have more questions or need further clarification, feel free to ask!

Knee Skin Issue: What Could It Be?

Hello! I hope you can help me with a concern I have about my knee. I’m a 20-year-old woman, standing at 160 cm and weighing 70 kg. Recently, I've noticed a troublesome patch on my knee. This area has become scaly and itchy, and it first appeared during my early teenage years. Initially, it manifested on my right knee as a tiny cluster of itchy bumps. Despite being small, scratching the area made it bleed and seemed to exacerbate the size of the irritation. Eventually, I also observed that the same patch developed on my left knee as well. After a while, I decided to consult a physician about this issue. Although I didn’t receive a concrete diagnosis, I was prescribed a topical ointment. Unfortunately, the cream didn’t have any labeling and I don’t know the specific ingredients, as it was a custom mix from the office. Thankfully, after applying it for some time, the patches on both knees cleared up entirely. However, a few years later, the condition returned. Two years back, I had a minor incident where I cut my right knee. The wound was small, roughly 1 cm, and I chose to let it heal naturally. This left me with a scar, which initially seemed fine for about a year. Then out of nowhere, the scar began to itch a bit. It was dry at first, leading me to peel off the dead skin, but soon the itchiness intensified, prompting me to scratch it. Now, I see that the irregularity is spreading again. It resembles the earlier issue, yet this time it’s smoother rather than scaly, although it’s just as itchy. I still have some of the ointment from the doctor’s visit, and applying it seems to relieve the itchiness temporarily. Just before I used the cream again, the area appeared to be inflamed due to persistent scratching. So, I am wondering what this could be. Is it wise to consult a dermatologist regarding this skin condition? I did some research online and the symptoms I've experienced in the past seem to align with psoriasis pictures, but the current manifestation, while spreading similarly, does not exhibit the same scaly characteristic. Thank you for taking the time to read my message. I apologize for the length and any confusion in my explanations, as English isn’t my first language. Wishing you all a great day!

Struggling with Long-Term Nasal Congestion

**Patient Overview:** 21-year-old male For the past three to four years, I've been dealing with persistent nasal congestion, which has been quite troublesome. Despite seeking help from two different ENT specialists and trying various medications, including multiple nasal sprays and drops, I haven't found any lasting relief. Unfortunately, the treatments have been largely ineffective. Both an endoscopy and a CT scan yielded no definitive results. The only temporary relief I've experienced comes from certain nasal sprays that I used excessively, leading to a rebound effect that made my condition worse. One of the ENT doctors indicated that there weren’t any viable solutions for my issue, while the other recommended consulting an allergist for further assistance. **Allergy Testing Results:** - **Immunoglobulin Level:** 283.4 IU/ml - Identified allergies include: - House Dust Mites: 4.90 IU/ml (Dermatophagoides farinae) - House Dust: 2.00 IU/ml (Hollister Stier) - Storage Mites: 1.30 IU/ml (Glycyphagus domesticus) - Casein: 1.10 IU/ml - Chickpea: 0.98 IU/ml - Sesame Seed: 1.22 IU/ml - Milk: 1.50 IU/ml - Egg: 1.30 IU/ml - Yogurt: 0.46 IU/ml - Common Ragweed: 1.20 IU/ml **CT Scan Findings:** - **MSCT Scan of the Paranasal Sinuses (Plain):** - **Nasal Cavity:** The septum is nearly central, but there are hypertrophied middle and inferior turbinates on the right side leading to fullness in the right nasal cavity. Concha bullosa is observed bilaterally. - **Bilateral Sinuses & Drainage Pathways:** Sinuses appear normal and the bilateral ostiomeatal complex is also normal. - There are enlarged soft tissue shadows of the adenoids measuring 32 x 14.5 mm, which may be causing mild to moderate narrowing of the air passage. - Bilateral tonsilloliths are present with no collection, and there is a need to rule out the possibility of chronic or recurrent tonsillitis. - **Anatomical Variations:** The Vidian nerve canals are normal, with no Haller or Onodi cells observed; Keros type II olfactory fossae are present on both sides. **Impression:** The findings suggest mild adenoid hypertrophy and nasal cavity fullness due to enlarged turbinates. Thankfully, the sinuses and ostiomeatal complex appear to be normal. Although I cannot recall the specific names of the medications and sprays prescribed—due to difficulty in reading my doctor’s handwriting—I conducted some research and learned that many of these medications are typically used for allergic rhinitis. Now, my physician has suggested that I consider starting immunotherapy and advised me to see an allergist. I find myself uncertain about the next steps, and I am seeking guidance on how to proceed.

Inquiry About Blood Test Results (Hormonal, Immune, and Metabolic Analysis)

Since my teenage years, I've encountered various hormone-related challenges. A minor amount of stress can throw my body into disarray, leading to insomnia, hair thinning, heightened anxiety, unexpected weight gain, muscle discomfort, and reduced sexual desire, among other issues. Additionally, I tend to be quite sensitive to heat, often experiencing migraines and nausea when the temperature rises. Recently, I noticed these stress-like signs resurfacing despite feeling relatively calm. In response, my physician conducted a series of tests checking for autoimmune problems and hormone levels. To provide some background, I am 38 years old, have never used hormonal contraception, and the blood samples were collected on the second day of my menstrual cycle. While I suspect my results fall within a typical range, I’m curious if they might still be linked to my symptoms: - FSH: 8.2 u/L - LH: 4.3 u/L - Testosterone: 1.1 nmol/L - SHBG: 104 nmol/L - Free Androgen Index: 1.1 All other results returned mid-range, except for a few that approached the low or high limits of normal, raising questions about whether it’s preferable to be at the extremes rather than in the middle: - Percentage of Lymphocytes: 1.9 x 10^9/L - Eosinophils Count: 0.1 x 10^9/L - Serum Potassium: 4.7 mmol/L - Serum Urea: 3.0 mmol/L - Serum Creatinine: 59 umol/L Moreover, I am inquiring about the relationship between my hair thinning and iron levels. Although I was previously informed that my iron and ferritin levels appeared normal, my ferritin measured below 60. From my research, it seems optimal ferritin for promoting hair health is typically between 70-100 or more. Any insights on this matter would be greatly appreciated.

Experiencing Changes After Stopping Hair Loss Treatments

At 5’9" and weighing 240 pounds, I want to share my recent experience with hair loss treatments. After 2.5 years of using finasteride and dutasteride, which I started when I was 19, I've decided to stop taking them due to unsatisfactory results and unwanted side effects. I'm curious about what to expect now that I’ve discontinued the use of these medications. Specifically, will I notice an increase in facial and body hair growth as my hormone levels return to their natural state? Before starting the treatments, I struggled with thin and patchy facial hair, which sometimes appeared to be thinning further. Additionally, despite using oral minoxidil, I haven’t observed any significant growth in my beard or body hair. In summary, my main question is: will ceasing dutasteride lead to improved hair growth across my body and face, since my DHT levels will normalize?

Bald Patches on My Leg

I’m an 18-year-old male, and I’ve noticed a bald patch shaped like a rectangle or oval on my leg, measuring approximately 3cm by 5cm, located just above my ankle. There's a similar patch on my left leg, but it’s smaller in size. I don’t believe these patches have always been there; I've had leg hair for the past few years, and I only just became aware of these areas. Does anyone have insights into what might be causing this? Currently, I’m taking a mild dosage of Roaccutane, just 10mg daily, and my recent blood tests show normal results.
