Inquiry Regarding Urine Analysis and EGFR Levels
Greetings, I am a 37-year-old male residing in Sydney, a non-smoker, and I take a proton pump inhibitor (PPI) on a daily basis. My height is 178 cm. I’m seeking insights based on personal experiences regarding my situation. Previously, I inquired about the implications of using a PPI and its effects on kidney health. After undergoing a blood analysis, I noticed a decrease in my estimated Glomerular Filtration Rate (eGFR) from a consistent 90 down to 73. Following this, I had a urine analysis which showed no signs of protein loss, although my urine appeared quite dilute. Could this dilution potentially impact the test results? Additionally, a follow-up blood examination indicated an eGFR of 74 with normal creatinine levels. What are your thoughts on this matter?

Thank you for sharing your situation. It's understandable to have concerns about changes in your kidney function, especially with the decrease in your eGFR and ongoing use of a proton pump inhibitor (PPI).
Main Points:
- Dilute Urine and eGFR: Dilute urine can affect the concentration of certain substances but typically doesn’t directly impact eGFR calculations.
- Understanding eGFR Changes: A drop in eGFR from 90 to 74 could indicate changes in kidney function, but several factors can contribute, and the absolute numbers are just part of the picture.
Explanation:
-
eGFR & Kidney Health: The estimated Glomerular Filtration Rate (eGFR) is a key measure of kidney function, helping to estimate how well your kidneys are filtering waste from your blood. A result above 60 is generally considered normal. Your eGFR dropping to 74 suggests a mild decline, which may need monitoring but is not necessarily alarming if stable and without other symptoms.
-
Dilute Urine: The dilution of urine can occur due to various factors, such as fluid intake or conditions affecting kidney concentration ability. While dilution itself doesn’t skew eGFR calculations, it can indicate other issues that might need addressing, particularly if it affects how well your kidneys are concentrating urine.
Next Steps:
-
Monitor Symptoms: Keep an eye on any symptoms such as swelling, fatigue, changes in urine output, or any other new issues. If any concerns arise, take note as this helps in future evaluations.
-
Hydration: Maintain a balanced fluid intake without overhydrating. This can help keep your urine and kidney function in check. Drinking water moderately throughout the day is usually a good approach.
-
Discuss the PPI: Consider discussing with a healthcare provider whether the PPI is necessary for your condition and its potential impacts on kidney health, as ongoing evaluation is important.
-
Follow-Up Tests: Plan for regular follow-up blood tests to monitor your eGFR and kidney function over time. This is important to identify any trends or changes.
-
Lifestyle Impacts: Maintain a healthy diet and lifestyle, as factors like diet can influence kidney health—consider reducing sodium intake and eating plenty of fruits and vegetables.
If you have further questions or if new symptoms arise, don’t hesitate to seek more information. It's important to feel supported and informed about your health.

Concerns Regarding Kidney Health
Profile: Male, Age 18, Weight 86kg, Height 6'2" Having had one kidney surgically removed at the age of nine, I've maintained good health with the remaining one. Additionally, I underwent an appendectomy roughly eleven months ago. Approximately six months ago, I noticed a change in my urine—suddenly it was yellow and frothy, a notable shift from the clear urine I was accustomed to, despite my consistent hydration. Two months later, I experienced an unusually dry mouth that persisted even after drinking fluids; my urine also developed a strong odor. Recently, I woke up with intense discomfort in my lower back that has since transitioned to a dull, lingering ache that isn’t severely bothersome. Since starting a relationship six months ago, my diet has included more fast food and sweetened items, contributing to a 7kg weight increase despite my active lifestyle. Could this be related to diabetes? Out of concern, I conducted a home urine analysis. The results indicated normal levels of protein and creatinine, with the exception of urine specific gravity measured at 1.010, which seems low considering my hydration levels, alongside an elevated vitamin C level—though I do not take supplements or consume excessive amounts of citrus fruits. To confirm, I performed a kidney function test at home, which returned a specific gravity of 1.015. Summarizing my symptoms: - Urine appears yellow, frothy, and malodorous despite adequate fluid intake - Persistent dry mouth and feelings of dehydration - Mild discomfort in the lower back - High vitamin C levels What could be the underlying issue? Am I potentially facing a urinary tract infection, kidney complications, or diabetes? (I have no history of diabetes). I appreciate any insights into my situation.
Understanding Post-Surgery Fever After Lung Wedge Resection
My father, aged 59, recently underwent a surgical procedure to excise a 1.8 cm PET-positive nodule located in the right lower lung lobe. They carried out a thoracoscopic wedge resection. The results from both the intraoperative frozen section and the pathology report indicated granulomatous inflammation accompanied by necrosis, with no signs of cancer present. Post-operatively, he developed a minor pleural effusion, which was subsequently drained. The fluid analysis revealed a serosanguineous appearance, but the cultures conducted have yet to return any positive results. Here are some relevant findings: - Negative results for Crypto and Coccidioides - Negative AFB tests for tuberculosis - Beta-glucan test returned negative - White blood cell count is within normal limits - Pathology indicates necrotizing granuloma and chronic inflammation, with no evidence of malignancy Occasionally, he experiences mild fevers during the night (approximately 101 degrees Fahrenheit) that subside with Tylenol, but overall he seems to be in decent health. I have a few inquiries: 1. Considering the pathology results confirmed the absence of cancer, how trustworthy are these results after undergoing a wedge resection? 2. Is it typical for necrotizing granulomas to lack a clearly identified infectious organism? 3. Are nighttime fevers a common occurrence following lung surgery, or should we be worried about potential infection? I’m seeking clarification on whether these developments are standard following such a surgical intervention.
Using Heating Pads for Kidney Stones
A 40-year-old man shares his experience dealing with kidney stones. Recently, he discovered a 4mm stone situated in the ureterovesical junction, which caused him what he describes as excruciating pain—his worst to date. After being examined, he was sent home with the hope that he could pass the stone naturally. Eight years prior, he experienced a kidney stone, but he claims that this current pain is far more severe. At home, he was prescribed opioids to manage his intense discomfort, but he has only needed to take one; he has been advised to use over-the-counter pain relief as necessary. Interestingly, he found no mention of heating pads in the treatment recommendations. Each morning, he continues to experience some level of pain, which he has been able to manage, yet he has not passed the stone just yet. He wonders if using a heating pad presents any issues, such as potentially increasing inflammation or complicating the passage of the stone. Despite having tried it a few times and noticing significant pain relief, he seeks confirmation that using the heating pad is indeed advisable. As a follow-up, he has already reached out to his doctor via the online portal but is still waiting for a response.
A Shocking Incident: My Friend's Struggle with Severe Burns
Hello from a developing nation! I’m posting for the first time, and it’s a bit of a pressing matter. Recently, my friend experienced a severe electric shock while attempting to fix a malfunctioning large generator. This led to deep second-degree burns. Thankfully, his nerves were not impacted. He has already undergone an autograft procedure along with a scar fibrosis operation for a portion of his burns. Before this surgery, he received injections aimed at mitigating swelling. Currently, he’s concerned about whether the surgical stitching was done properly or if it might result in complications later on. Moreover, are there any recommended treatments—be it surgery, ointments, supplements, or medications—that could alleviate the swelling? It has been nearly six months since the incident, and he finds himself needing painkillers to cope with the discomfort from the swelling on the lower half of his body that remains unoperated. I will share updates about his recovery soon, including the section that hasn’t been treated yet. We urgently need advice, as he’s contemplating changing doctors and possibly seeking care in another country. Additionally, I overlooked an unusual detail: post-surgery, both his middle and ring fingers have developed swelling. This is peculiar since they were unaffected by the burns and showed no issues prior to the operation, and there’s no pain in those fingers. He is a 26-year-old male who is currently taking only painkillers and applying povidone iodine, with no additional ointments used.
Localized Redness at the Urethral Opening in Males
I noticed something earlier while performing a self-examination. There appears to be redness present at the opening of the urethral meatus, specifically affecting only one side. I felt no unusual sensations accompanying this observation. My last sexual encounter took place back in January, during which protection was used, and it involved receptive anal intercourse. Could this redness indicate a urinary tract infection, or is it simply a case of irritation? I'm uncertain and would greatly appreciate any insights or guidance on this matter. Additionally, I had a urinalysis conducted last month, and the results came back normal.
