Understanding Low Creatinine and BUN Levels: Should You Be Worried?
I’m a 34-year-old female weighing 143 pounds, and I don’t smoke or consume alcohol. My supplement routine includes 2000 IU of vitamin D3 multiple times a week, pumpkin seed oil three times weekly, and iron every other day. Recently, I noticed some concerning changes in my lab results. My previous blood tests indicated a low mean corpuscular hemoglobin concentration (MCHC), prompting me to occasionally increase my iron intake. In addition, I had been dealing with a vitamin D deficiency that drastically decreased from 81 ng/mL to 46 ng/mL within just 11 days, and then further declined to 38 ng/mL after another 15 days. On top of that, my ferritin levels plummeted from 66 to a mere 26. I’m now facing several troubling symptoms: I often feel short of breath, I’m losing weight unintentionally, I experience dizziness, have noticed increased hair loss, intermittent chest pain, and a racing heart rate. My calcium levels have also been affected, dwindling from the mid-10s to 9.2. Could these developments indicate an issue with my kidneys? I’ve shared my lab results for further review.

The changes you're experiencing in your lab results and the symptoms you’re describing could be concerning and may indicate several issues, but they do not conclusively point towards kidney problems. It’s crucial to consider the entirety of your health context and symptoms when interpreting lab values.
Understanding Your Situation:
- Low Creatinine and BUN Levels: Lower than average creatinine and Blood Urea Nitrogen (BUN) levels can suggest good kidney function or, in some cases, issues like malnutrition, liver disease, or overhydration. They are not singularly diagnostic.
- Symptoms: Your symptoms—shortness of breath, weight loss, dizziness, hair loss, chest pain, and racing heart—could result from various factors including anemia (indicated by low ferritin and MCHC), vitamin D deficiency, or possible electrolyte imbalances given your fluctuating calcium levels.
Next Steps:
-
Focus on Nutrition and Supplement Intake:
- Since your ferritin levels indicate iron deficiency, consider foods rich in iron (like lean meats, beans, and dark leafy greens) and potentially increasing your iron supplement, but do so with caution and not beyond the recommended doses.
- Enhance your vitamin D intake through dietary sources (fatty fish, fortified foods) and consider re-evaluating your supplementation with a healthcare provider to address the significant decrease.
-
Monitor Symptoms:
- Keep a detailed diary of your symptoms including their frequency, intensity, and any triggers. This will help track changes over time and provide essential information for your healthcare team.
- Note any increasing severity in your shortness of breath, chest pain, or dizziness, as they may require urgent attention.
-
Hydration and Electrolyte Balance:
- Stay well-hydrated but be cautious of overhydrating, especially if there are concerns about your kidney or liver health. Adjust your fluid intake based on your thirst and activity level.
-
Consider Comprehensive Lab Tests:
- Request comprehensive blood tests that include complete blood count, liver function tests, and electrolytes to get a clearer picture of your overall health status.
- It may be beneficial to get your thyroid function checked, as thyroid disorders can impact energy levels and metabolic health.
-
Consultation with Experts:
- While I cannot advise you to visit a healthcare provider directly, I strongly encourage you to seek an evaluation from a qualified healthcare professional who can interpret your lab results in the context of your overall health and provide targeted investigations and treatments.
Please prioritize addressing your symptoms and seeking a thorough evaluation. Your health is important, and it's wise to involve a healthcare provider for a comprehensive assessment. If anything worsens or you experience new severe symptoms, don’t hesitate to seek immediate care.

Unusual Heart Sensation
I’m an 18-year-old, weighing 50 kilograms and standing at 170 centimeters (and yes, I’m aware that I’m quite slender). For the past couple of years, I’ve developed a habit of smoking about half a pack of cigarettes each day. So, the other day I was lying on my left side, relaxing, when I stumbled upon an unusual sensation. It felt as though my heart was pulsating so intensely that it was almost outside my body. Out of curiosity, I pressed a bit on the area and was instantly hit with a rush; my head started to tingle, my vision momentarily blurred, and it felt as though my heart dropped. It was as if my entire system had malfunctioned. Just for context, I’ve experienced something similar before after a ketamine overdose, and it persisted for about a month afterward, occurring occasionally while trying to sleep or during random moments in bed. This current episode has me quite anxious, especially since it hasn’t happened in a while, but this time felt particularly alarming.
Mass on the Glottis

Current Medications: Uses a Symbicort inhaler and takes Concor tablets. Main Concern: A mass was detected during a gastroendoscopy carried out a year ago. There is no report of pain, but the patient experiences mild hoarseness. What might be the diagnosis?
Experiencing Heart Palpitations Following Chest Impact
I'm a 17-year-old female who has struggled with tachycardia for several years, having been diagnosed with postural tachycardia syndrome (POTS) about five years ago, although I haven't pursued further testing because I haven't completely lost consciousness. Recently, over the past month or two, I've started to experience sensations of my heart skipping beats, accompanied by difficulty in breathing during these episodes. These occurrences have become significantly more frequent, even when I'm at rest. Five years ago, I underwent a Holter monitor test, which indicated primarily tachycardia with occasional premature ventricular contractions (PVCs), but nothing alarming was found. In early December, I was struck hard in the chest by an elbow while in a mosh pit, which resulted in some pain when taking deep breaths for a few days. My sternum became bruised and slightly swollen, and it remained tender to touch for about two weeks, but this discomfort was manageable. I still feel some soreness when stretching, although it’s not severe. Additionally, I have diagnoses of Crohn’s disease and hypermobile Ehlers-Danlos syndrome (HEDS), and I am currently on immunosuppressants. Given these circumstances, would it be advisable for me to seek medical evaluation, or could these symptoms be considered typical?
Understanding My Experiences with Dissociation and Physical Symptoms
Hello everyone! I'm 15 years old and I’ve been grappling with intense feelings of dissociation recently. About two years back, I experienced what I now refer to as a "silent seizure" for the first time. It happened around 2 PM while I was at school in the band hall. Suddenly, I found myself zoning out completely; I was just sitting there, disassociated from reality, until it dawned on me that I couldn’t seem to reconnect with my surroundings. Feeling lost, I turned to a friend and anxiously asked, "Where am I?" She chuckled, unaware of the seriousness of my situation, but I stood up and wandered out of the classroom, aimlessly walking towards the bathrooms. The sensation was akin to being in a dream—you know you’re somewhere, yet you can’t fully engage with the moment for what felt like 5 to 10 minutes. Strangely, I even had the feeling of observing myself from above as I moved through the halls, like a scene from a dream. In a state of panic, I contacted my mom. By the time I managed to leave school, my mind was clearing. She took me to her workplace where a colleague checked my blood sugar levels, revealing it was low. I had eaten that day, so this was unexpected (especially since my mother also faces issues with low blood sugar). This occurrence was unprecedented for me; thankfully, I haven’t faced such low levels since then. In the following weeks, I experienced intermittent dissociative episodes, prompting me to visit a doctor. I underwent blood tests, an electrocardiogram (EKG), and a routine examination. Everything appeared normal, except I was diagnosed with anemia—something my mother and sister also deal with. I walked away from that appointment without any real explanations, and after a while, the episodes subsided—thankfully, a relief. FAST FORWARD TO NOW: (15 years old) (Potentially relevant context) Recently, I’ve been enduring severe heart and chest discomfort. I’ve been noticing irregular heartbeats, sporadic strong pulsations, and sharp pain localized in my heart region and upper right chest. Lying on my side can be quite painful, and sometimes I struggle to take deep breaths. I make it a priority to get a full eight hours of sleep each night, I take daily vitamins, and I’m actively involved in competitive cheerleading, maintaining a healthy fitness level for my height and weight. We sought medical advice again, underwent numerous tests, and, once more, everything checked out fine. My heart was deemed healthy, and all other measurements were satisfactory. Initially, we suspected anxiety might be a factor, but my mom is hesitant to consider antidepressants, believing that my age may limit treatment options. She has recommended that I hydrate more and practice breathing exercises (which is somewhat ironic since I struggle to breathe when these pains occur, yet I don’t argue). UPDATE: During practice today, I unexpectedly experienced my first "silent seizure" episode in two years. It was more disconcerting than I recalled. I lost track of my location again and couldn’t re-engage with reality. It felt as if I was observing those around me from a dream-like vantage point. This realization frightened me, thinking that I had moved past these episodes. It took about ten minutes for me to regain my awareness of my environment. Additionally, this week, I noticed moments of dissociation, albeit not as intense as previous episodes. I found myself vacantly staring, and my vision felt oddly lazy, frequently. It's worth noting that I do not have a lazy eye. I plan to document these occurrences meticulously, and if they persist, I will consult my doctor again. Meanwhile, if anyone has suggestions about what might be happening to me, I would greatly appreciate it. Is this potentially linked to anxiety? I’m genuinely confused about my condition!
Identifying a Mysterious Brown Circle on My Scalp
Age: 21 Gender: Female Height: 5'4" Weight: 175 lbs Ethnicity: White (Scottish/Irish) Location: California Current Medication: Testosterone injection administered subcutaneously in the thigh While I was having my hair dyed blue, my girlfriend noticed a perfectly circular brown mark on my scalp. It resembles a circle that appears to have been made with a brown marker. The size of the ring is similar to my thumb’s tip and contrasts sharply with the lighter shade of my scalp. There is no evidence of hair thinning or loss around this circle; we only discovered it because we were parting my hair. I’m curious if this could be connected to the brain fog or headaches I’ve been experiencing lately. I looked online, and while ringworm was suggested, it doesn’t match my symptoms since there are no bald patches or flaky skin. I’m open to answering any additional questions to help clarify this situation, as it's causing me some concern.
