Muscle Inflammation: Insights on Elevated Liver Enzymes and Exercise - Neurology

Share to:

excuse me?


In May, I went to the hospital for blood tests due to fatigue and yellowing of the eyes, and it was found that my GOT (AST) and GPT (ALT) levels were significantly elevated.
There was a suspicion of hepatitis, and muscle enzymes in the blood were also elevated.
Later, a liver biopsy showed no issues with the liver, so the doctor concluded that the elevated levels were likely due to muscle inflammation.
Doctor, could this be rhabdomyolysis? Since I started working out at the gym in early May, aside from drinking more water, what else should I pay attention to? Should I reduce my exercise intensity in the future? If exercise is causing fluctuations in GOT and GPT levels, what impact does this have on my body? What should I do about the yellowing of the whites of my eyes?

First, check the CPK levels and whether there is blood in the urine, as these may indicate the presence of rhabdomyolysis.

Understanding muscle inflammation and its relationship with elevated liver enzymes is crucial, especially for individuals who have recently increased their physical activity levels. In your case, the elevated levels of liver enzymes (GOT and GPT) alongside symptoms such as fatigue and jaundice (yellowing of the eyes) raise important questions about the underlying causes and necessary precautions.

Firstly, it's essential to understand that elevated liver enzymes can indicate liver inflammation or damage, but they can also be influenced by other factors, including muscle injury or inflammation. In your situation, the fact that liver biopsy results showed no liver issues suggests that the elevated enzymes may indeed be related to muscle inflammation rather than liver disease. This condition is often referred to as "exercise-induced muscle damage," which can occur after intense physical activity, especially if you are not accustomed to such levels of exertion.

When you engage in strenuous exercise, particularly resistance training or high-intensity workouts, muscle fibers can sustain micro-tears. This process leads to the release of muscle enzymes, such as creatine phosphokinase (CPK), into the bloodstream, which can subsequently elevate liver enzyme levels. It's important to note that while some elevation in liver enzymes can be a normal response to exercise, significantly high levels warrant further investigation.

To address your concerns about whether you might be experiencing rhabdomyolysis (a serious condition resulting from muscle breakdown), it is crucial to monitor specific markers such as CPK levels and check for symptoms like dark urine, severe muscle pain, or swelling. If you notice any of these symptoms, it is advisable to seek medical attention promptly.

In terms of managing your exercise routine, here are some recommendations:
1. Gradual Increase in Activity: If you have recently started a new exercise regimen, consider gradually increasing the intensity and duration of your workouts. This approach allows your body to adapt and reduces the risk of muscle injury.

2. Hydration: Staying well-hydrated is vital, especially during and after exercise. Dehydration can exacerbate muscle damage and increase the risk of kidney complications associated with rhabdomyolysis.

3. Rest and Recovery: Ensure you allow adequate recovery time between workouts. Rest days are essential for muscle repair and overall recovery.

4. Nutrition: Focus on a balanced diet that supports muscle recovery. Incorporate protein-rich foods to aid muscle repair and consider anti-inflammatory foods like fruits, vegetables, and omega-3 fatty acids.

5. Monitoring Symptoms: Keep an eye on any unusual symptoms, such as persistent fatigue, muscle pain, or changes in urine color. If these occur, consult your healthcare provider for further evaluation.

Regarding the yellowing of your eyes, this symptom, known as jaundice, can indicate an underlying issue with liver function or bilirubin metabolism. Since your liver biopsy showed no issues, it may be related to muscle inflammation or other factors. However, it is essential to follow up with your healthcare provider to rule out any serious conditions.

In conclusion, while exercise is beneficial for overall health, it is crucial to listen to your body and make adjustments as needed. If you have concerns about your liver enzyme levels or experience any alarming symptoms, do not hesitate to seek medical advice. Regular monitoring and open communication with your healthcare provider will help ensure your safety and well-being as you pursue your fitness goals.

Intense exercise (such as running a marathon) can indeed lead to an increase in GOT levels, while the impact on GPT is relatively minor. The elevation in GOT levels is due to the release of this enzyme from muscle tissue and is not related to liver function. Resting and rehydrati...
