Concerns About Kidney Health: Interpreting My Lab Results
I’m a 35-year-old female, weighing 165 pounds and standing around 5 feet 6 inches tall. Currently, my BUN/Creatinine ratio has risen to 27, while my CO2 levels are notably low at 17. Additionally, my alkaline phosphatase is slightly reduced, measuring at 42. On a positive note, my estimated Glomerular Filtration Rate (eGFR) is 120, which seems to indicate a healthy kidney function. I’d appreciate some assistance in understanding these results. All other tests from my Comprehensive Metabolic Panel (CMP) came back normal, though I do have elevated lipid levels—albeit still within an acceptable range thanks to my high HDL. Please note that I am not seeking medical advice and would value any insights you might have.

Your lab results show a mix of findings that merit interpretation. Here’s a breakdown of your key results and what they might mean:
-
BUN/Creatinine Ratio of 27:
- A higher BUN (Blood Urea Nitrogen) to creatinine ratio can suggest dehydration, increased protein intake, or kidney function issues, but your eGFR of 120 indicates good kidney function. In isolation, this ratio can indicate some other factors affecting hydration or diet.
-
Low CO2 Levels (17):
- Low CO2 may suggest acidosis or respiratory issues, but it can also result from metabolic causes such as a high-protein diet or fasting. It’s essential to consider any symptoms you may have, including fatigue or difficulty breathing.
-
Alkaline Phosphatase of 42:
- While this value is slightly below the normal range, it is usually not concerning unless correlated with other liver function abnormalities or specific symptoms.
-
eGFR of 120:
- This is indicative of excellent kidney function, as normal values are typically above 90. It suggests that your kidneys are efficiently filtering waste.
-
Elevated Lipid Levels:
- While it's good that your HDL (the “good” cholesterol) is high, keep an eye on your overall lipid profile. Keeping a balanced diet and regular exercise can help manage lipid levels.
Next Steps:
-
Stay Hydrated:
- Ensure you are drinking enough fluids, which can help normalize your BUN/Creatinine ratio. Aim for at least 8-10 cups of water per day, adjusting based on activity level and climate.
-
Monitor Symptoms:
- Keep track of any symptoms you might experience, especially regarding energy levels or breathlessness, which may provide more context for your low CO2 levels.
-
Evaluate Diet:
- Consider your protein intake and overall nutrition. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can support your metabolic health and lipid levels.
-
Follow Up:
- Continue regular check-ups and lab work as recommended by your healthcare provider. Monitoring your kidney function and lipids alongside other metabolic markers will allow for proactive health management.
These steps should help you maintain your overall health and provide a clear picture of how your metabolic functions are operating. If you notice any significant changes in your health or new symptoms arise, be sure to follow up accordingly.

Concerns After Gallbladder Surgery (Three Weeks Post-Op) - Is It an Infection?
Profile: - Age: 35 - Gender: Female - Height: 5 feet 4 inches - Weight: 160 pounds - Ethnicity: Asian Duration of Symptoms: Last Three Weeks Location: United States Recent Medical History: Nearly three weeks have passed since my gallbladder removal surgery. Over the last few days, I've noticed a small amount of unclear fluid coming from the incision. I just observed what seems to be pus oozing from the surgical site. Although there is slight tenderness when I move or touch the area, it isn't painful. Thankfully, I haven’t experienced any fever or chills, and there’s no unpleasant odor emanating from the wound. Should I continue to clean it with soap and water, or is it necessary for me to visit the emergency room for further evaluation?
Exploring Inositol and CoQ10 for Managing PCOS Symptoms
As a 28-year-old female, I have faced the challenges of polycystic ovary syndrome (PCOS) since my teenage years. Starting from the age of 16, I have dealt with highly irregular menstrual cycles, occurring anywhere from three to eight months apart. My diagnosis has been substantiated through two ultrasounds and blood tests revealing elevated androgen levels. Despite maintaining a healthy diet and leading an active lifestyle—balancing my work as an environmental biologist with gym sessions alongside my husband—I continue to wrestle with weight management. Other symptoms impacting my daily life include significant hair loss, unwanted facial hair, and persistent fatigue. In my journey to manage PCOS, I previously sought counsel from a gynaecologist, who primarily suggested hormonal birth control as the main approach to alleviate my symptoms. Although I adhered to this recommendation for several years, the hormonal changes negatively impacted my mood, leading me to discontinue its use. Another alternative proposed by my gynaecologist involved androgen blockers, but these are not suitable for me since my husband and I plan to start a family in the next two to three years. Recently, my research led me to discover that supplements like Inositol and CoQ10 might effectively combat insulin resistance and lower androgen levels. They are purported to improve various symptoms associated with PCOS, including the regulation of ovulation, all while boasting minimal adverse effects. I am curious about the viability of these supplements as alternatives to hormonal birth control or androgen blockers in managing my PCOS symptoms.
Seeking Clarity on My Spinal Tap Results: A Bit Anxious
I am a 31-year-old woman experiencing a continuous headache for the past four months, accompanied by feelings of nausea and exhaustion. I take Lexapro each day to manage my mental health. I have a history of migraines and headaches, but this recent episode doesn't align with my previous experiences. Here are the findings from my spinal tap: - **Opening Pressure of Cerebrospinal Fluid (CSF)**: 9 cm H₂O - **Presence of Red Blood Cells (RBCs) in CSF**: 2,570 - **Total Protein Level in CSF**: 107 mg/dL - **ACE Level in CSF**: 4.4 - **Other Tests on CSF**: Results were normal. - **Brain MRI and MR Venography**: Both tests yielded normal results. - **Blood Test Results**: Normal results were obtained. Given these results, I'm feeling a bit uneasy and I’m hoping to better understand what they might indicate about my health.
Concern Regarding Persistent Tongue Bump with White Coating
I am a 24-year-old male, standing at 190 cm tall and weighing 109 kg. For the past five weeks, I've experienced a peculiar issue on my tongue. Specifically, there's a noticeable bump on the right side near the tip, which I believe may have been developing over time, although I'm not entirely sure about that timeline. Recently, I've been troubled by an unusual sensation, including dryness, an odd taste, and a slight decrease in my sense of taste. Additionally, I've observed a white coating that is more pronounced on the aforementioned side of my tongue. The bump in question: - Does not cause any pain. - May have increased slightly in size over the weeks, though I'm uncertain. - Appears smooth with a pink surface, free of bleeding or ulceration. Given that this issue has persisted for over a month, I am feeling quite anxious and am concerned that it may indicate a serious problem. I have no significant medical history, but I confess that my dental hygiene has not been up to par, as I haven’t been brushing regularly. At this moment, I’m also under medication for H. pylori, known as Pylera, but this tongue concern predates my treatment. I am a non-smoker and am reaching out for any insights on this condition. Has anyone experienced something similar? Could this be a sign of irritation, infection, or something benign? I really appreciate any guidance you could provide. Thank you!
Experiencing Clear Fluid from Ear with No Discomfort: Should I Wait for My Appointment?
I am a healthy 57-year-old female, weighing 120 pounds and standing 5 feet 5 inches tall. My daily medications include 100 mg of Losartan for effectively managed high blood pressure, 200 mg of Lyrica taken twice daily for post-herpetic neuralgia, 100 mg of Synthroid following treatment for thyroid cancer, and a combination hormone replacement therapy patch. Additionally, I take Zyrtec and Flonase every day to combat allergies. Since October, I have been dealing with persistent tinnitus in my right ear, accompanied by some pressure and a muffled sensation. Recently, I've noticed that when I speak, it feels akin to the sensation I experience when my ears clear during a flight after chewing gum—my voice sounds amplified in my head. I've scheduled an appointment with a physician's assistant in an ear, nose, and throat (ENT) office for the end of March due to my worries about the tinnitus and any potential hearing impairment. Yesterday, I noticed that my ear emitted a clear fluid. Thankfully, there was no associated pain. The fluid was somewhat thicker than water, completely odorless—unlike the unpleasant discharge I recall from my daughter's ear infections—and there was no sign of blood. Could this indicate a perforated eardrum? I suspect this might be the case, but can this occur without an underlying infection? Should I seek attention sooner than my appointment in March? I would prefer to avoid urgent care during flu season; however, if this situation is serious, I am prepared to take precautions and visit.
