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.

Seeking Answers for Nipple Discharge
Hello everyone, I’m a 22-year-old woman, standing at 5'6" and weighing 157 pounds. I find myself in a somewhat awkward situation as I’ve been experiencing a green discharge from one of my milk ducts for about two years now. More recently, within the last year, I’ve noticed that two additional ducts have started to leak, although the fluid from those is clear. To clarify, I’m not actively trying to express this fluid; I discovered it during sporadic self-examinations. Initially, I consulted a physician when the issue was limited to just the one duct. They performed tests on the fluid and conducted an ultrasound, but everything came back normal, with no cause for concern, and I was reassured that it shouldn’t pose any health risks. Despite that, my anxiety has grown due to the recent developments. The discharge is only occurring in one breast, and with a family history of breast cancer—three of my relatives have unfortunately passed away from it—plus my grandmother's recent diagnosis, I feel increasingly alarmed. I also want to point out that I have never been pregnant, and I do not experience pain or notice any lumps. I’m reaching out to see if any of you have insights on what this condition might be. Should I seek a second opinion from another doctor or a specialist, or is this a common occurrence? For context, I don’t smoke, I occasionally enjoy alcohol, and I'm currently prescribed Strattera, but that’s a more recent addition to my routine.
Experiencing Constant Heat at 40: Seeking Insights
I have always had a tendency to feel excessively warm for as long as I can remember. I stand at 6 feet 1 inch tall and weigh around 250 pounds. I lead a highly active lifestyle, participating in yoga weekly, taking brisk walks every day, and ensuring I consume a minimum of three liters of water daily. Currently, I’m not on any medication, and my hormone tests indicate normal levels. I’ve also had my thyroid evaluated, and it showed no irregularities. Living in Edmonton, Alberta, my heat tolerance is quite remarkable. For instance: 1) I’m comfortable wearing shorts all year round at home, and I venture outside in shorts even in temperatures as low as -10 C (14 F). 2) During -40 C (-40 F) weather, I can walk for 30 minutes dressed in sneakers, sweatpants, shorts beneath, a t-shirt, and a winter jacket, along with gloves and a hat, feeling perfectly fine. 3) At nighttime, I need three fans directed at me while I sleep, and I often leave the window open, even in winter. 4) I rely on air conditioning in my vehicle as soon as temperatures reach 15 C (59 F). 5) In spring, summer, and fall, I use those three fans as well as a large frozen gel pack (approximately 2 feet by 1 foot) placed under a lightweight blanket to help cool down enough to sleep comfortably. 6) When I go to work, I opt for dress shorts and a dress shirt, and I require a fan at my workstation. I frequently retreat to the chilly server room, which is part of a data center, to cool down. 7) There are instances when I’m putting my child to bed; they have commented on the warmth radiating from me and have requested that I stop because it’s too hot. My optimal sleeping temperature is around 15 C (59 F). Is there anyone else, especially men, who can relate to this experience or provide insight into what could be causing these symptoms? I often feel lightheaded and sweaty when I can’t cool down adequately!
Enlarged Lymph Nodes in Neck and Armpits
I am a 24-year-old male with no notable family medical history, and I abstain from smoking and drinking. Beginning around May 10th, I began experiencing discomfort in my right armpit, which subsequently spread to both armpits. The discomfort was accompanied by nerve pain radiating down to my elbows and fingertips. I sought treatment from a Family Nurse Practitioner on May 29th, receiving a steroid injection, but there was no noticeable improvement. About a week later, on approximately June 8th, we identified swollen lymph nodes in my neck and armpits, all roughly the size of peas, tender (especially in the armpits), and mobile. My provider prescribed azithromycin, suspecting cat scratch fever, yet this medication did not yield any changes. Now, having completed the course, I’ve noticed additional lymph nodes in my neck and one located above my collarbone; these are soft, a bit larger than a pea, mobile, and sore to the touch. I underwent a CT scan with contrast, but I'm still awaiting the results. Over the past month, my symptoms have mostly included mild fatigue (similar to a cold), muscle discomfort, a sore throat (which appears slightly irritated), bilateral deep ear pain, and minor jaw pain on the right side. There have been no occurrences of night sweats, weight loss, or notable fatigue. Update: My lab results are satisfactory, with my white blood cell count showing an upward trend within a week, now sitting at 7.8, though still within normal limits from an initial 5.1. What could this indicate? Should I take any particular steps moving forward?
Should We Seek a Second Opinion on Alzheimer’s/Dementia Diagnosis?
I need some advice! To summarize a lengthy situation briefly, my father (71 years old) has exhibited troubling signs for roughly two years. His cognitive difficulties include a substantial decline in vocabulary, frequent forgetfulness of names, places, and tasks, repetitive questioning with no memory of prior inquiries, decreased logical reasoning, an inability to summarize movies or events immediately after experiencing them, increased aggression, a decline in his previously good math skills, poor spatial awareness (evidenced by numerous dings and scratches on the car), and difficulty maintaining conversations. We consulted with a neurologist who ordered an MRI, CT scan, and lumbar puncture, and I’ll outline the findings below. We had our concluding appointment today, and the neurologist stated, "Given that amyloid levels are over 600, he does not have Alzheimer’s and shows no signs of dementia.” Although I am not a healthcare professional, the results seem concerning, and I am puzzled as to why a 71-year-old man is struggling to function in everyday life. Considering the findings detailed below, should we pursue a second opinion? Or is the neurologist correct in their assessment that everything is normal? **MRI Findings:** The examination revealed lesions in the periventricular and subcortical white matter, suggesting chronic ischemia. Additionally, small areas of tissue damage were noted in the external capsules bilaterally and in the right basal ganglia, potentially due to small infarcts. A minor area of tissue loss was also present in the left thalamus. There were no acute changes, hemorrhages, or microbleeds, nor any space-occupying lesions observed. A subsequent arterial angiography of the intracerebral vessels indicated no significant stenosis. The ventricular system’s size and shape remain unchanged, as does the sulcal pattern. **CT Scan Summary:** The CT images exhibited low-density areas in the periventricular and subcortical regions, indicative of chronic ischemia. Tissue loss was also seen in the external capsules and the right basal ganglia, possibly from previous infarcts. There were no obvious acute changes or any space-occupying lesions. However, the ventricular system appeared enlarged, suggesting mild central atrophy, but no signs of mesial temporal atrophy were noted. Some cortical atrophy was documented, primarily in the parietotemporal areas on both sides (GCA 2). The bone window showed no abnormalities. **Lumbar Puncture Results:** - Amyloid beta 1-42: 624 ng/L in CSF - Amyloid beta 1-42 / 1-40 ratio: 0.072 - CSF Phosphorylated tau (p-tau): 232 ng/L - CSF Total tau protein: 1110 ng/L
Concerns About Floating Stools and Pancreatic Health
Hello everyone, I am a 46-year-old woman with a generally good health record, although I deal with asthma and otosclerosis. In late February 2024, my family and I contracted stomach viruses that lasted for a brief span of two days. Ever since that incident, I have been experiencing floating stools on a nearly consistent basis. In May 2024, my gastroenterologist recommended a stool analysis, which indicated normal levels of fat and normal pancreatic function. Tests also ruled out Giardia and H. Pylori infections. Fast forward to October 2024, I underwent an MRCP both with contrast and without, which returned normal results. In February of this year, my primary care physician repeated the pancreatic function test, yielding normal results once again, along with normal bile levels. Additionally, a blood test for Celiac disease came back negative. However, since March, I have developed three new symptoms: 1. **Chronic Urticaria**: I consulted an allergist about this condition who suspects it was triggered by my Covid booster shot (the fifth or sixth, I think) that I received on February 14th. I was prescribed a week’s course of Claritin. While I still experience occasional itchy patches that lead to hives during the night, this issue has mostly improved. 2. **Sharp Rib Cage Pain**: I have been feeling a sharp pain beneath my rib cage on several occasions since early April 2025. This discomfort is fleeting but certainly troubling. 3. **Upper Back Tightness**: Lately, I have noticed tightness and achiness in the center of my upper back, specifically between my shoulder blades and at the base of my neck. On occasion, the discomfort radiates down to the middle of my back and sometimes affects the left side beneath my shoulder blade. Moreover, the floating stools remain a persistent issue. I have read numerous articles expressing concerns about radiologists potentially missing small pancreatic lesions—reports indicate this can happen in up to one-third of scans. I find myself feeling anxious about this possibility. Should I consider seeking a second opinion? I would appreciate any advice or insights you might have regarding the accuracy of MRCPs or whether there are additional tests or scans I should consider requesting. Thank you for your help!
