I was diagnosed with rhabdomyolysis once. (CK levels were around 10k)
Now I am wondering: am I more likely to get another one? Or does one's history has nothing to do with it? I wasn't able to find any information on this.
Based on what I was able to find, the answer is "it depends". Rhabdomyolosis can carry with it damage to the kidneys or other systemic problems. If that is the case, then it is possible that the threshold of what caused the condition is lowered.
Now the risk factors for Rhabdo are:
Since this site is dedicated to physical fitness, the biggest repeat risk factors would be those related to severe exertion, heatstroke, or genetic muscle diseases. You can't do much about genetic issues, but you may still be able to exercise without rhabdomyolysis if you pay more attention to fatigue.
The biggest defenses you will have against rhabdo (shortened form of the word) will be:
These are going to be your best defenses, but they are not magic formulas. Supplementing with sodium bicarbonate (baking soda) doesn't make you immune to rhabdo, it simply helps your body recover from fatigue better. The most important thing you can do is when your muscles are fatigued to the point where standing or walking is laborious your need to stop exercising and go into recovery mode.
It also might be a good chance to evaluate your training environment. Working with others can be a tremendous motivator, but if no-one is going to call you on over-working and instead coerce you to "push through the pain" then that training environment might actually be toxic for you. It's best to be surrounded with people who work hard, but recognize the importance of recovery.
