Understanding Granular Casts in Urine Analysis
A 26-year-old male, standing at 5 feet 8 inches tall and weighing 365 pounds, does not partake in smoking, drinking, or drug use. I’m sharing the findings and remarks from my recent consultation with my physician below: - Moderate mucus threads present - Occasional bacterial presence noted - Hyaline castings detected: 10-25 lpf - Granular casts: 5-10 per low-power field (lpf) - Occasional calcium oxalate crystals observed - White blood cells (WBC): 2-4 per high-power field (hpf) - Specific gravity of urine: 1.032 - Urobilinogen levels: 3.0 mg/dl - Ketones present at 40 mg/dl (2+) - Protein level: 30 mg/dl (+1) - Bilirubin: small amount The doctor conveyed, "In my opinion, these findings do not suggest an infection; therefore, antibiotics are not necessary at this moment." Further, the doctor noted, "The urinalysis indicates some irregularities, but we cannot determine a specific cause aside from potential dehydration. No signs of metabolic issues or acute kidney injury are present, and there’s no elevated glucose from the serum comprehensive metabolic panel. The dietary choices you’ve made, particularly your lower-carb regimen in recent weeks, could be influencing these results. I recommend increasing your water intake and scheduling a follow-up with your primary care provider in two weeks. Again, I do not believe an infection is involved, so antibiotics are not required." A comprehensive metabolic panel was also conducted, and the doctor remarked that my kidney function appears to be normal. Overall, my blood test results were exceptional. Currently, my diet consists primarily of low-carb foods, including ground turkey, ground beef, eggs, avocados, cherries, oranges, bananas, and various vegetables. The doctor suspects that my dietary habits are the root of these findings. However, I have read that granular casts may indicate kidney issues, which has left me feeling anxious and confused. I tend to worry about my health, and hearing that granular casts can be associated with kidney disease triggered my anxiety. I’m looking for clarity on this situation.

It's understandable to feel anxious about health findings, especially when they involve terms like "granular casts." Let's break down your urinalysis results and provide some clarity.
Main Points
Granular casts in urine can sometimes raise concerns, but in your case, your physician's interpretation suggests that these findings are likely not indicative of a serious kidney issue. Your doctor emphasized hydration and dietary factors as contributing elements.
Explanation
-
Granular Casts: These are byproducts of kidney function and can be seen with various conditions; however, they do not always indicate kidney disease. Since your kidney function tests are normal and your doctor noted the absence of infection or serious metabolic issues, it's less likely that your granular casts are a cause for alarm.
-
Other Findings: The presence of mucus threads, occasional bacteria, and WBCs suggests mild irritation or an inflammatory process, but again, your doctor believes this does not signify an infection. The notes about your diet (low-carb) and potential dehydration may account for other findings like ketones and specific gravity.
-
Diet and Hydration: Your current low-carb diet might contribute to some of the urinalysis results, particularly the presence of ketones and possibly affecting hydration levels.
Next Steps
-
Increase Water Intake: Focus on drinking more fluids throughout the day. Aim for 8-10 cups (2-2.5 liters) of water daily, adjusting based on your activity level and climate. Good hydration can help dilute your urine and may improve your urinalysis findings at your next follow-up.
-
Monitor Diet: Consider gradually increasing your carbohydrate intake through healthy sources like fruits, whole grains, or legumes, as this might help balance your ketone levels. Consult a nutritionist if you're unsure about making changes safely.
-
Track Symptoms: Keep a record of any symptoms you experience, such as changes in urination, abdominal pain, or swelling, over the next few weeks. This information will be helpful for your follow-up with your primary care provider.
-
Follow-Up Appointment: Continue with the scheduled follow-up in two weeks to reassess your urinalysis results and any ongoing concerns. Bringing a list of your findings and any changes you’ve made will provide a comprehensive view for your doctor.
Reassurance
It's important to remember that while health concerns can feel overwhelming, many factors can influence lab results. Focus on making the recommended lifestyle adjustments, and try to maintain a balanced outlook. If anxiety continues or you have further concerns, consider discussing them with your healthcare provider. They can help you create a plan that prioritizes both your physical and mental well-being.

Swelling and Pain in the Testicles
M19, I have a concern regarding a situation down below, but I’m feeling shy about consulting a healthcare professional. It all started a couple of months back when I noticed a few small, painless white spots appearing on my shaft and scrotum. Although they're minor and don’t leave any marks when removed, they can be quite bothersome. Thankfully, the number of these spots hasn’t increased significantly. I’ve been contemplating visiting a doctor; however, I’m currently tied up with a demanding 60-hour per week summer internship, and the embarrassment I feel also makes it difficult. I am sexually active, typically engaging with one or two new partners each month, and I must confess that I haven't always prioritized safe practices, which I am now regretting. While I suspect I don’t have genital herpes because these spots don’t resemble typical symptoms associated with that condition, the uncertainty lingers. Initially, when these spots appeared, I experienced some discomfort during urination, but that symptom has thankfully subsided. Recently, however, I became alarmed when one of my testicles unexpectedly swelled up and began to hurt. It seemed to emerge without any warning; I woke up one morning to find that one testicle was notably larger than the other. There appears to be a dent in a specific area, which coincides with where the pain emanates from. The discomfort isn’t continuous; it only occurs when the area is agitated, such as while sitting awkwardly or upon touching it. I suspect this might be related to the white spots, yet this issue began to surface only a few days ago, while the white spots have been around for a while. This may sound somewhat misguided, but I genuinely hope this is a treatable condition like gonorrhea or chlamydia; I’m really anxious that it isn't something severe like testicular cancer, herpes, or a similar diagnosis. Additionally, I should mention that I am on Trazodone for insomnia. I don’t use cannabis and limit my alcohol consumption to weekends only.
Understanding Blood Pressure Readings
Hello, I'm a 27-year-old woman who isn't taking any medications. Recently, while using my personal blood pressure monitor at home, the device displayed an "error" message before registering a reading of 68/47. I decided to recheck my blood pressure, and the subsequent readings were 117/75, 115/73, and finally 119/78. Given this situation, can I reasonably conclude that the initial reading was inaccurate and choose not to monitor my blood pressure for the remainder of the day?
Frequent Nosebleeds
For the past year and a few months, I have experienced frequent nosebleeds, occurring up to three times a day. Each episode usually lasts between 10 to 20 minutes, specifically affecting the left nostril. During these episodes, I often feel a wave of dizziness, warmth, and confusion. There are instances when the bleeding seems to flow backward, which adds to my concerns. This ongoing issue has significantly disrupted my sleep and impacted my performance at work. As a 22-year-old woman, standing at 4'11" and weighing 115 pounds, I have been diagnosed with alpha-gal syndrome and Lyme disease. The cause of these frequent nosebleeds remains unclear to me, and I seek to understand what might be contributing to this situation.
Prepping for Blood Tests: Exercise Considerations
Profile: 34-year-old male from the USA, weighing 200 pounds and standing at 6 feet tall. As part of managing my chronic illness, I’m undergoing blood tests to keep an eye on my health status. Recently, I've been feeling revitalized and have completely reintegrated physical activity into my daily routine, almost as if I am experiencing a remission from my autoimmune issues. Given the importance of accurate results for my Complete Blood Count (CBC) and Comprehensive Metabolic Panel (CMP), I’m curious whether I should refrain from intense workouts in the days leading up to the tests. What is the suggested duration for avoiding exercise to ensure the integrity of the results?
Seeking Advice on Recent Health Concerns
Hello Doctors, I’m a 31-year-old male who maintains a healthy lifestyle, avoiding smoking, recreational drugs, and alcohol. Regular workouts are a significant part of my routine, as I strive to stay fit. In February 2025, I underwent septoplasty and also dealt with a fracture during that time, which contributed to some emotional distress. This situation forced me to halt my exercise regimen until I resumed in June. Additionally, I started taking Pexep 25 under the guidance of a healthcare professional. Over the past few weeks, I’ve been experiencing significant stomach bloating at night, coupled with episodes of dizziness and a frustrating rage that feels beyond my control. My blood pressure has also seen a decline; it was typically around 119 to 120, but now I find it fluctuating between 103 and 105. I would appreciate any insights or suggestions you may have regarding my current health issues. Thank you.
