Post-Hiking Biochemical Analysis: CK, CK MB, LDH, and Aldolase Levels
A 35-year-old male weighing 64 kg and standing at 167 cm completed a moderately intense hike covering 20 km, with the first blood draw occurring 45 hours post-activity and the subsequent test taken 66 hours after the excursion. Here’s a recap of the relevant lab results: 📊 CK Levels: - 42 hours post-hike: 3039 U/L (reference value: <174 U/L) - 66 hours post-hike: 3080 U/L (reference value: <174 U/L) 📊 CK-MB Level: - 66 hours post-hike: 56 U/L (reference value: <24 U/L) 📊 LDH Levels: - 42 hours post-hike: 337 U/L (reference value: <247 U/L) - 66 hours post-hike: 380 U/L (reference value: <247 U/L) 📊 Aldolase Level: - 20 U/L (normal value: <7.6 U/L) Further analyses: - CRP and ESR were reported within normal limits. - Physical symptoms noted were only mild muscle soreness, with no signs of weakness, and overall good health was reported. This raises a question: are these results common for someone just starting out? I consulted with my doctor today, who indicated that this situation does not warrant concern. Nonetheless, my tendency to have health-related anxieties left me feeling unsettled, especially in light of my elevated CK levels. Additionally, I recalled an incident from four years ago when a random Anti-Jo-1 result was indicated through an Immunoblot test, although I exhibited no symptoms at that time. Follow-up testing via FEIA later confirmed negative results, and the original test was conducted for an entirely different purpose. Since then, I’ve remained vigilant regarding my CK levels and their implications.

It's understandable to feel anxious about elevated CK levels, especially after engaging in a physically demanding activity like hiking. Your lab results show significantly elevated levels of creatine kinase (CK), CK-MB, LDH, and aldolase, which can all stem from intense physical exertion. Here’s a closer look at your results and actionable next steps.
Summary of Your Lab Results:
- CK Levels: Your CK levels (3039 U/L and 3080 U/L) are very high, indicating muscle damage or stress, which is common after strenuous exercise, particularly for those who may be new to such activities.
- CK-MB Levels: The elevated CK-MB (56 U/L) may suggest muscle injury, as this enzyme is often associated with heart muscle damage but can also rise in skeletal muscle injury.
- LDH and Aldolase Levels: Both LDH and aldolase levels are also elevated, further pointing towards muscle strain or damage.
Explanation:
These elevated levels are not unusual following an intense exercise session, especially if you are not accustomed to such activities. Muscles can release these enzymes into the bloodstream during strenuous workouts as they undergo repair and recovery processes. The absence of severe symptoms (like significant weakness or pain) and normal inflammatory markers (CRP, ESR) support that this is likely a temporary response to your hike rather than a sign of a serious condition.
Next Steps:
-
Rest and Recovery:
- Allow your body time to recover. Avoid strenuous physical activity for several days to help your muscles heal.
- Focus on gentle movements or low-intensity exercises to keep blood flowing without straining your muscles.
-
Hydration and Nutrition:
- Stay well-hydrated; water helps flush out toxins and supports muscle recovery.
- Ensure your diet includes adequate protein and nutrients that support muscle repair (e.g., lean meats, fish, legumes, nuts, fruits, and vegetables).
-
Monitor Symptoms:
- Keep track of any gradual changes in your muscles and overall health. If you notice new, concerning symptoms like severe pain, swelling, or persistent fatigue, consider following up.
-
Follow-Up Testing:
- Discuss with your healthcare provider the possibility of re-testing CK levels in a few days or a week to monitor any downward trends, which can help reassure your mind regarding your recovery.
-
Manage Anxiety:
- If health-related concerns are causing significant anxiety, consider speaking with a mental health professional or engaging in relaxation techniques such as mindfulness or meditation.
Overall, while your lab results are notable, they reflect a response to physical exertion rather than a chronic health issue, especially given the slight muscle soreness and normal inflammatory markers. Keep communicating with your doctor about your worries—they can provide tailored advice and reassurance. Let me know if you need more information on any of these points!

Pushing Boundaries or Overdoing It?
For several years, I was an active competitive cheerleader, which meant my body was constantly in motion and often sore due to rigorous practice sessions, especially during competition periods. When I transitioned to college and stepped away from cheerleading, I paused my workout routine. This hiatus led to feelings of guilt over my inactivity and sparked a desire to shed some pounds. Consequently, I began monitoring my food intake, utilizing a scale to track my macronutrients. I focused on increasing my protein consumption, something I previously struggled with due to my picky eating habits regarding meat. Around the same time, one of my roommates was dealing with disordered eating, which influenced my own mindset and behaviors, pulling me into a similar downward spiral. During a difficult couple of months, my eating habits fluctuated between consuming limited meals and intermittent fasting. Ultimately, I managed to break free from that harmful cycle and began to enjoy healthier, more balanced meals once again. Simultaneously, my sleep schedule was severely lacking, averaging only 3 to 5 hours each night. Post-Thanksgiving holiday, I established a more consistent routine in December, committing to daily workouts to alleviate the guilt and anxiety surrounding food and boost my sense of productivity. My regimen included a 30 to 45-minute workout, a brief stretch, a 20-minute incline walk, along with several local trail walks spanning about 4 to 6 miles. However, this rapid increase in physical activity took a toll on my body. I developed a pump bump on my right heel and suffered from severe Achilles tendinitis in my left ankle, which became so swollen that the tendon was not visible. A visit to the podiatrist revealed the issue stemmed from a bone growth at the front of my ankle joint, potentially a remnant of a previous cheer injury. I was advised to switch to shoes with a higher heel, take anti-inflammatory medication, and engage in physical therapy. Though the swelling subsided and the pain lessened in the interim, I was eager to get back to college and get into my fitness routine. Upon returning, feeling as though I had fallen behind, I ramped up my workouts significantly. I started a regimen that included an hour of weightlifting followed by over two hours of inclined walking on the treadmill, aiming to burn more than 1,000 calories from Monday through Friday, with weekends reserved primarily for rest, featuring an abdominal workout and leisurely walks. Regrettably, my roommate's calorie tracking habits led me to regress into similar behaviors. I avoided using the food scale this time, hesitant to return to previous unhealthy patterns, yet I still substantially reduced my caloric intake, attempting to keep it below 1,000 calories while burning over that amount through exercise. My approach included moderate meals Monday through Thursday, reserving weekends for larger meals and occasional treats. On weekdays, I typically consumed a third of a banana before workouts, engaged in three hours of intense exercise, then took an energy drink before classes. Post-class, I’d have some cucumber or a piece of fruit before dinner, which generally consisted of protein, a whole-grain English muffin, and salad. If I had room left, I’d enjoy a Greek yogurt for dessert. So far, this strategy has yielded favorable results; I've lost almost 14 pounds since my last checkup in mid-December, and my stomach discomfort has lessened. However, after a 10-mile walk this past Sunday, I began to experience significant pain in my right shin, assuming it might be shin splints but continuing to work out as usual. The week has been challenging, caught between the urge to maintain a 1,000-calorie burn while grappling with persistent pain, even while at rest. The discomfort is concentrated on the front part of my shin, spanning about the size of a quarter, and is painful to touch. Movement aggravates the sensation, making it hurt to walk or even lift my leg while sitting. There's noticeable swelling and warmth, and the pain seems to intensify in the evening, causing discomfort even when resting in bed. I sought care today, and while an X-ray showed no significant issues—a relief—the physician suspects it might be tendonitis. I was initially fearful of a stress fracture, having heard stories of athletes pushing through such injuries, resulting in more severe complications. Given that the X-ray was clear, I am reassured, but I'm still anxious to continue my workouts, as I feel uneasy just remaining inactive and eating without sufficient exercise. I would appreciate any insights into my situation and whether it appears to align with the diagnosis in terms of allowing me to continue training—perhaps avoiding excessive incline walking during this time.

Prolonged Exposure to Magnets: A Query about Safety
Hello everyone, I’m a 26-year-old male and I have a question regarding my work habits. I habitually carried a magnet attached to my hard hat to pick up metal shavings and manage wiring diagrams. Given that these magnets are positioned close to my head, I’m wondering about the safety implications. Are there any research findings related to long-term exposure and potential harm? I can't help but notice that when I carried the magnets, I experienced more intense headaches, though it coincided with the hot summer months, leading me to think dehydration might have played a role. I also do not have any medical implants or serious injuries, apart from a previously torn ACL. I'm intrigued about the matter, particularly since my current magnets are quite weak, and I'm considering upgrading to more powerful ones.
