Understanding Vitamin D and Iron Deficiencies: When Will I Feel Better?
At 22 years of age, I stand at 5 feet 10 inches and weigh around the mid-150s. I recently discovered through a blood test conducted on February 16th that I have a deficiency in vitamin D, specifically at a level of 18. Additionally, my ferritin and iron saturation levels are also low, though my overall iron level is reported as 53, which is considered normal per my charting app. This winter has taken a toll on my well-being, prompting me to seek your insights on a few matters. Since before the blood tests and continuing afterwards, I've been grappling with various symptoms; the most prominent among them include anxiety, depression, a lack of interest and enthusiasm, overthinking, muscle pain, light sensitivity, occasional dizziness, and persistent fatigue that fluctuates. Overall, I just don’t feel like myself anymore. Currently, I am following my doctor's recommendation by taking 5000 IU (125 mcg) of vitamin D, which I have been on for about two and a half weeks. My primary concern is how long it typically takes for these supplements to take effect. Are the symptoms I'm experiencing common for someone with my current levels? I also take an iron supplement every other day. I’m curious if there are additional suggestions or methods that might aid my recovery aside from what I am already using. While I have noticed some slight improvements, many of the issues linger on. I would greatly appreciate any insights or advice that other healthcare professionals could offer. Thank you!

It's understandable that you're feeling concerned and frustrated about your health, especially with the symptoms you've described alongside your deficiencies in vitamin D and iron. Here are some key points to consider regarding your situation:
Main Points:
- Improvement Timeline: It can take several weeks to months for both vitamin D and iron supplementation to positively influence your symptoms.
- Connection to Symptoms: Your symptoms such as fatigue, anxiety, and muscle pain can be linked to low vitamin D and iron levels.
- Additional Support Strategies: Incorporating lifestyle changes and self-care practices can enhance your recovery process.
Explanation:
- Vitamin D: At a level of 18 ng/mL, you indeed have a deficiency. The dose you're taking (5000 IU daily) is a common recommendation for deficiencies and may take 4 to 8 weeks for you to start feeling significant improvements in your energy levels and mood, and up to 6 months for full normalization.
- Iron: Even if your overall iron level appears normal, low ferritin indicates lower iron stores, which can cause fatigue and muscle weakness. Iron supplementation can take a few weeks to start improving these symptoms, and consistency is crucial.
- Symptoms: The symptoms you are experiencing—fatigue, changes in mood, muscle pain—are common among people with vitamin D and iron deficiencies.
Next Steps:
- Continue Supplements: Keep taking your vitamin D as directed and your iron supplements every other day. Be consistent, as it may take time for your body to respond.
- Monitor Symptoms: Keep a symptom diary to track any changes over the next 4-8 weeks. Note any improvements or new symptoms, which can help in evaluating your progress.
- Balanced Diet: Focus on a diet rich in iron (like red meat, fish, poultry, lentils, and fortified cereals) and vitamin D (found in fatty fish, fortified dairy, and eggs). If possible, spend some time outdoors for natural sunlight exposure, as this can help boost vitamin D levels.
- Hydration and Sleep: Stay hydrated and maintain a regular sleep schedule. Sleep greatly influences mood and energy, so ensure you're getting enough restorative rest.
- Mindfulness and Support: Engage in mindfulness practices like meditation or yoga to help manage feelings of anxiety and depression. Connecting with supportive friends or mental health resources can also help your overall emotional well-being.
Remember that healing is a process, and it's important to be patient with yourself. If your symptoms do not improve or worsen, you may want to follow up with your healthcare professional for further evaluation. Keep focusing on your health and well-being, and I wish you all the best on your journey to feeling better!

Frustration with My Endocrinologist: Lack of Attention and Incomplete Testing
Age: 34 Gender: Male Height: 5 feet 10 inches Weight: 270 pounds Ethnicity: Caucasian Issue Duration: More than one year. Location: Canada Current Medications: Testosterone Replacement Therapy (100 mg/week), Minoxidil, and Finasteride for hair loss. --- I had an appointment with my endocrinologist a few weeks ago, and it left me feeling doubtful and less confident. There were no adjustments made to my medication. The hormone panel I received only included TSH and total testosterone. It's hard to overlook the fact that my feet have been severely swollen for over a year, causing me significant pain while walking. Regular shoes are unwearable for me, and this issue is constantly on my mind. --------- If you need further context, here are the key points: 0: My TRT is prescribed at 100mg per week. I’m a mature man, clearly past my prime, and I have no interest in superficial validations or social media conditioning. I focus on my career, not on achieving an unattainable body. 1: I have clinically confirmed low testosterone levels, having undergone four blood tests over two years prior to starting TRT 1.5 years ago. This situation has been persistent for nearly four years now. 2: Since starting TRT, I have often gone without proper testing. I had bloodwork done about a month ago, but I feel like I'm navigating this without guidance. 3: The blood tests requested by my endocrinologist were lacking crucial hormonal data. All I got were results for TSH and total testosterone. I have no details on estrogen levels (which is crucial), SHBG, free testosterone, or any other pertinent hormones. 4: The swelling in my feet began over a year ago, right after I started TRT. Currently, I can barely wear conventional shoes and have resorted to walking around in oversized crocs. My general practitioner has referred me to cardiologists for a range of tests, including echocardiograms. So far, there are no signs of heart failure or strokes. However, I do experience an elevated heart rate and slightly high blood pressure, which isn’t alarming yet, but my doctor warned me about a possible delay in my heart's conduction. 5: Conversations with friends led me to believe the issue might be linked to estrogen. Given how many men share their TRT experiences, I’ve realized how under-informed I am regarding my estrogen levels and overall hormonal state, especially considering my foot condition. Despite bringing up these concerns, my general practitioner is reluctant to conduct further tests. 6: Currently, I am on the same dosage and treatment plan, with no changes made. The thought of enduring another year with feet that can’t fit into proper shoes is incredibly disheartening. Moreover, if I am experiencing swelling in my feet, I can’t help but wonder what other underlying issues I might be experiencing that remain undetected.
Seeking Guidance on Abnormal EKG Results at 21
At the age of 21, I’m reaching out for advice due to some concerning health issues. I'm a woman who previously experienced preeclampsia at 19. Since that episode, my health has deteriorated significantly. I've been plagued by episodes of dizziness, blurred vision, rapid heartbeats, and persistent headaches. Recently, I've started feeling weakness and tingling on the left side of my face. I’m unsure whether this could be intensified by my anxiety. The catalyst for my recent hospital visit was mild chest discomfort, during which I underwent an EKG. The results revealed an abnormal T wave inversion, noted to be -7. Here are the specifics of my EKG: - Ventricular Rate: 108 bpm - Atrial Rate: 108 bpm - P-R Intervals: 128 ms - QRS Duration: 86 ms - QT Interval: 338 ms - QTc: 452 ms - P Axis: 44 degrees - R Axis: 64 degrees - T Axis: -7 degrees Additionally, I underwent troponin tests—both came back normal, as did a chest x-ray. Despite these negative results, I can’t shake the feeling that there's something more concerning going on. My palpitations and physical sensations have been increasing, and I've noticed visual disturbances too. As a mother to a two-year-old, the thought of not being around for her future is terrifying. I've gone through various tests, including a tilt table test and a stress test, and now I'm considering a CT angiogram of my heart and a carotid ultrasound. Given my family history—my father suffers from coronary artery disease and has had three heart attacks, compounded by his obesity—I feel validated in my concerns. I struggle with obesity myself but have made strides, having lost nearly 50 pounds. I also deal with high cholesterol and diastolic hypertension. I would sincerely appreciate any recommendations or advice that could help me navigate through these troubling symptoms. Thank you for your support!
Recovering from a Near-Death Experience: Seeking Psychological Support
At the age of 22, I faced a life-threatening situation related to medication-induced cardiogenic shock. My blood pressure plummeted to an alarming 55/29 with a heart rate of just 54. Memories of that harrowing time are vivid; I fought to stay conscious while in the Emergency Department, the RESUS area, and the ICU. I can clearly recall the moment they punctured my femoral artery to insert the ECMO device. Unfortunately, they did not manage my pain effectively, and I endured significant discomfort during the procedure. Before this, I could see a crowd of medical professionals in a frantic effort to stabilize me. They administered epinephrine multiple times, along with 80 mcg of norepinephrine and other medications, but when my blood pressure failed to respond, they informed my family that "the receptors are all occupied by the medications." That moment was terrifying; I genuinely thought I might not survive. Additionally, I experienced a choking sensation and felt as though I couldn’t get enough air, which I later discovered is referred to as "air hunger." Two weeks later, these traumatic memories continue to replay endlessly in my mind, with these being just a few of the distressing instances that I find hard to shake off. In my discussions with my therapist, we concluded that increasing my therapy sessions from once a week to twice would be beneficial. Despite this, I still feel deeply unsettled by everything that transpired. The reality is that I almost lost my life; my parents were informed that I might not survive my first night in the ICU. I carry a sense of shame, too, due to the worry and distress I caused to those around me, which stems from a mistake that was unintentional, yet still brings me embarrassment. Ironically, I was volunteering at the hospital when my colleagues noticed my symptoms and quickly took my initial blood pressure before sending me to the emergency room. I would greatly appreciate any advice or support during this challenging time. It’s clear to me that I still feel a heavy weight of trauma from this experience.
Understanding Fluctuating Cortisol Levels: A Personal Experience
Hello everyone! I’m a 27-year-old female (27F) and I’d like to share my recent experience with cortisol testing. About two months ago, during a routine blood test, I received unexpected results showing significantly low cortisol levels for the first time. The blood draw occurred around 8:50 AM after I had fasted for approximately 10 hours, and my cortisol level was measured at 19 nmol/L, whereas the lab's normal morning range is between 166 and 828 nmol/L. Last week, I consulted my endocrinologist—whom I visit for issues related to PCOS—regarding this low reading. She recommended that I head to the emergency room immediately, despite it being two months since the initial test. Once at the hospital, they conducted another cortisol evaluation later that afternoon around 4 PM, which returned a level of 155 nmol/L. Subsequently, they performed a stim test around 9 PM that showed a value over 400 nmol/L. It’s worth mentioning these tests were conducted without fasting. The medical team reassured me that everything appeared normal since my body was able to produce cortisol effectively. After thorough testing, they discharged me, advising that I should schedule a follow-up with my endocrinologist within a few weeks. I’ve been reflecting on what might influence my cortisol levels, specifically the Symbicort inhaler I occasionally use for asthma and a 1% hydrocortisone cream for eczema that I apply sparingly. When I mentioned these to my doctor, she indicated that they should not significantly impact cortisol production. However, I’ve been extremely fatigued lately, requiring 10 to 12 hours of sleep plus additional naps, yet I still struggle to feel rested enough to manage daily tasks or study effectively. Strikingly, I don’t display the common symptoms typically associated with low cortisol levels. This brings me to my confusion: is it typical for cortisol levels to vary so greatly? Could my initial low result have been erroneous, or could the afternoon and non-fasting nature of the ER tests skew the results? Should I remain concerned? The medical staff suggested the level of 19 was quite low and potentially hazardous, but I left without clarity and no definitive solutions. I appreciate any insights or shared experiences you might have! Thanks in advance for your help! :)
Running Low on Antidepressants
Age: 33, Height: 5'3", Weight: 170 lbs Currently, I’m prescribed bupropion hydrochloride extended-release, taking 200 mg twice daily. This has been part of my routine for several years. Recently, I started a new job and, unfortunately, my health insurance won't be active until April 1st. As of now, I have only 17 days' worth of medication remaining. Financial constraints prevent me from consulting a doctor, and my work training schedule complicates any attempts to do so. To manage my supply, I’m contemplating reducing my dosage to just one pill daily, which would extend my medication for about 34 days. However, I have concerns about whether this would be effective or beneficial. I may face a two-week gap without my medication once my supply ends, leaving me uncertain about my next steps.
