Although not a common occurrence, this disease often comes from trauma of some kind,although as ehealer already pointed out,people who lead a reckless lefestyle, are at greater risk.
As for treatment,after diagnosis, it is done symptom based. So, if the ph is off, and the person has either too much or not enough potassium,then potassium is either given or the blood potassiumm is diluted
At all events IV fluids are given and if there is enough urine production,diuretics (like lasix) can be taken to stimulate the flushing out of toxins from the kidneys.
It is the kidneys that suffer the most,because as the muscles break down, the contents of the muscles themselves go into the blood (thats the myoglobin) and when all of that is filtered through the kidneys,the kidneys will fail
Most of the time, dialysis,especially if kidney failure is in the acute stage,is needed.
The one thing I took away from researching this is the warning to always always drink plenty of water after strenuous exercise...and thats important advice for everyone;from daily work outs to weekend warriors. So many people trying to burn excess calories these days...how many really drink enough water after all of their exercise?
Thank you for this question, needed this advice!
