Could My Recent Exercise Be Causing High Liver Enzyme Levels?
I’m a 28-year-old male, weighing 120 pounds and standing 5 feet 7 inches tall. Currently, I have not been diagnosed with any health conditions; however, I've experienced ongoing symptoms such as dizziness and lightheadedness, alongside occasional headaches. There’s also a minor issue with colon inflammation. As for my medications, I take lorazepam at a dosage of 0.5 mg once or twice weekly for the past two months to manage my dizziness when it becomes overwhelming. Additionally, I have been taking 500 mg of Tylenol every eight hours for five days to help with discomfort. In the last two months, I have undergone blood tests on three occasions. The first two tests indicated mostly normal results. However, just ten days after receiving my last normal test results, I discovered that my liver enzymes are elevated. Fortunately, imaging of my abdomen using a CT scan with contrast showed a liver that appears otherwise healthy. The readings showed AST at 149 and ALT at 69. I typically consume alcohol only a few times a year and I don't believe that my Tylenol intake has been excessive. Notably, I began a new workout routine at the gym three days before my latest blood test, which consisted of light cardio and moderate weight training, as I’ve been relatively inactive lately. By the time of my blood test, it had been about 72 hours since my last workout, and any muscle soreness had subsided. This is the only possible explanation that comes to mind for the elevated levels. Otherwise, I might need to start being concerned about my liver health.

Your recent exercise may be a contributing factor to your elevated liver enzyme levels, but other elements need to be considered as well. Elevated liver enzymes like AST (aspartate aminotransferase) and ALT (alanine aminotransferase) can sometimes occur after significant physical activity, particularly if your body is adjusting to a new workout routine. However, continued monitoring is essential to ensure there are no underlying concerns.
Explanation:
-
Exercise Impact: Intense or new exercise routines can cause temporary increases in liver enzymes due to muscle stress. Since your workout began shortly before the blood test, this could explain the transient rise.
-
Other Factors: Your use of medications (like Tylenol) can affect liver enzyme levels, particularly if used frequently or in higher doses. Although you mentioned not exceeding recommended doses, it's essential to ensure you're using it appropriately.
-
Symptoms: The dizziness, lightheadedness, and headaches you’re experiencing may relate to several factors, including possible dehydration, low blood pressure, or reactions to medications.
Next Steps:
-
Hydrate: Ensure you are drinking plenty of water, especially after workouts, to support overall health and liver function.
-
Monitor Symptoms: Keep a diary of any symptoms you experience, especially dizziness and headaches. Note the frequency and intensity to identify any patterns.
-
Review Medications: Double-check your Tylenol dosage and frequency. It might be useful to discuss the duration of use to ensure it aligns with safe practices for your liver health.
-
Follow-Up Testing: Schedule follow-up blood tests as advised by your healthcare provider to monitor liver enzyme levels. This will help determine if the elevation resolves on its own or needs further investigation.
-
Exercise Adjustment: Consider moderating your exercise routine temporarily until you understand the cause of the elevated liver enzymes. Gradually increase the intensity and pay attention to how your body feels during and after workouts.
Please stay mindful of your body’s reactions, and if symptoms worsen or new concerns arise, be proactive in seeking further evaluation. Your health is important, and monitoring these changes closely will help guide your actions moving forward.
