Elevated Creatinine Levels: Could Protein Oats Be the Culprit?
Hello everyone, this is my inaugural post, and I find myself feeling quite anxious about sharing my situation. I am in desperate need of clarity, as both my doctors and family members seem to dismiss my concerns, yet my mind is racing with worry. In June 2024, I underwent a blood test, and my creatinine levels were completely normal. Shortly thereafter, I began a workout regimen and incorporated protein shakes into my routine for a couple of months. However, I ceased these practices in September when my semester commenced. Since then, I have not engaged in any exercise or taken additional protein supplements. Fast forward to February 2025, when I began consuming 7g protein oats overnight, about twice per week, mostly at night. To my dismay, just last week, I had another blood test, and the results showed a slight increase in my creatinine levels. At a petite 46 kg (160 cm) with limited muscle mass, I am now anxious that I may be experiencing the early stages of kidney disease. What exacerbates my anxiety is the fact that prior to obtaining the test results, I was asymptomatic. However, I have since noticed some discomfort in my sides and lower back pain. It’s important to note that I have had bouts of lower back pain in the past, particularly after lifting heavier loads, leading me to question whether my symptoms are truly physical or simply a manifestation of my anxiety. All other kidney-related markers appeared to be within the normal range. Therefore, I would like to pose this question: Could my creatinine elevation be linked to the protein shakes I previously consumed or the regular intake of oats? Should I be genuinely concerned about this, or is it sufficient to conduct a re-test and keep an eye on the situation?

It's understandable to feel anxious when receiving unexpected lab results, especially concerning your kidney health. Elevated creatinine levels can indicate changes in kidney function, but there could be several reasons for this. Let’s clarify your situation, considering both your dietary habits and your health concerns.
Key Points:
-
Potential Influences on Creatinine Levels: Your previous protein shakes and current protein oats consumption may have had some impact on your creatinine levels, but they are not the sole cause. Factors such as muscle mass, hydration status, and physical activity also contribute.
-
Understanding Creatinine: Creatinine is a waste product from muscle metabolism, filtered by the kidneys. Elevated levels can indicate a decrease in kidney function, but slight increases can also occur due to temporary factors like diet, exercise, or even dehydration.
Explanation:
Even after stopping protein supplements and not exercising for a few months, your body can still respond to dietary changes. The protein content in your overnight oats is relatively modest (7g), so it's likely not a major contributor. Moreover, feeling discomfort or back pain doesn’t necessarily signify kidney issues—especially since you have had similar discomfort in the past.
Next Steps:
-
Stay Hydrated: Ensure you are drinking enough water each day. Dehydration can elevate creatinine levels, so this simple step can be beneficial.
-
Monitor Symptoms: Keep track of any new or changing symptoms, including any discomfort you feel. If your pain persists or worsens, consider evaluating this with a healthcare professional.
-
Re-Test Creatinine Levels: It's prudent to follow up with another blood test to monitor creatinine levels. This will help ascertain if the rise was a one-time fluctuation or an ongoing issue.
-
Maintain a Balanced Diet: Focus on a well-rounded diet that includes a variety of nutrients without excessive protein. High protein intake can stress the kidneys slightly, especially if kidney function is compromised.
-
Manage Stress and Anxiety: Since you mentioned anxiety about your health, consider incorporating stress-reducing activities such as meditation, yoga, or gentle exercise, as long as it doesn't exacerbate the pain.
Conclusion:
While it's important to take any elevation in creatinine levels seriously, many factors can contribute to this result, and immediate concern may not be warranted. Focus on hydration, monitor your symptoms, and consider retesting to get a clearer picture. If your anxiety persists, discussing these feelings with a healthcare professional might also be helpful. Remember, you are not alone in this; many people share similar concerns, and it's okay to seek clarity and support.

Intense Pain in Left Thumb
Greetings, I’ve been experiencing a piercing pain at the tip of my left thumb intermittently. This discomfort is situated within the thumb rather than on the outer skin. It primarily affects the underside of the thumb and surrounds the base of the nail. The pain seems to extend only to the first skin fold, specifically around the distal phalanx. When applying pressure, I’ve noticed some red streaks appearing beneath the surface, alongside the white area. I trust this explanation is clear. This issue has persisted for over a year, occurring sporadically but intensifying as time has passed. Could this be a cause for concern? A bit about myself: I am a 25-year-old female with no significant medical issues in my background. I previously smoked cigarettes for three years, transitioned to vaping, and have been vaping for six years now. I maintain an active lifestyle, frequently going to the gym and participating in various sports such as indoor football and pickleball. I don’t have any known allergies.
Persistent Need to Stretch Legs While Seated
I experience a significant discomfort when seated, particularly when my knees are bent at about a 90-degree angle. This sensation compels me to stretch my legs straight, and if too much time passes without doing so—typically around every five to six minutes—the urge intensifies to an uncomfortable level that’s hard to manage. It’s more than just a desire to fidget; fully extending my legs tends to offer the greatest relief. Adjusting my position provides some comfort, but it doesn’t alleviate the feeling nearly as effectively as a full stretch does. This issue predominantly arises when I remain stationary in a chair. Occasionally, I notice a similar feeling when I’m lying down, but these instances are relatively rare compared to the frequent occurrences while sitting. I consulted a relative who is a medical professional about this discomfort, and they suggested that it doesn’t appear to align with Restless Leg Syndrome. However, since this isn't their specialization, I acknowledge that there may be a chance of error. * What could potentially be causing these sensations? * Does anyone else relate to this experience? * Are there methods available to help manage or diminish this feeling? I would greatly appreciate any advice or insights.
Resources for Safe Mouse Cleanup
While it may not be a typical inquiry for a healthcare professional, I find myself in need of guidance. Recently, we had an uninvited mouse visitor in our home, and unfortunately, it left droppings in my children's toy storage and on the changing table. I am seeking advice on how to effectively disinfect all affected items or determine if disposal is necessary to prevent any health risks. My children are quite young, at 2.5 years and just 4 months old. If they’ve potentially been exposed to mouse droppings, should I reach out to their pediatrician? For reference, I’m a 32-year-old female, standing at 5'6" and weighing 140 pounds, not currently on any medications.
Excessive Electrical Shocks Encountered
Hello everyone! This is my inaugural post here since I don't frequently use Reddit. I'm a 15-year-old male, and I've recently been experiencing an unusual frequency of electrical shocks. Whenever I come into contact with anything that is either highly charged or conductive, I receive a sharp, irritating jolt. This situation has become increasingly bothersome. For instance, I can only grasp my Mac charger by the cord and not the plug itself. I'm curious if anyone has insights into why this is happening. Please let me know; I hope it's nothing serious! 💕
