Rhabdo is short for rhabdomyolysis, a serious condition where injured muscle breaks down and spills its contents into your blood.
Think of it like this:
What happens
- Your muscles get damaged from overuse, heat, injury, or other stress
- They release proteins and salts that normally stay inside the muscle
- Those substances flood the bloodstream. Your kidneys try to filter them out, but there is too much too fast. That can injure the kidneys and cause other problems like nausea, vomiting, very low blood pressure, irregular heartbeat, or seizures.
Who can get it
Anyone, even people in great shape like athletes and marathon runners. Risk is higher if you:
- Work or exercise hard in heat, or have a physically demanding job like firefighter, first responder, military service, or outdoor work
- Have had trauma, a long surgery, or a severe infection
- Take certain medicines like amphetamines or statins, have a genetic muscle condition, or have low phosphate or low potassium
Symptoms
It can look like heat exhaustion. Watch for:
- Muscle aches, severe cramps, or joint pain
- Dark brown or tea-colored pee
- Feeling very weak, tired, or unable to finish a workout you normally could
Treatment
This is an emergency. Get care right away.
- Mild cases: rest, get out of the heat, and fluids, sometimes with baking soda added, to help flush the kidneys
- Severe cases: IV fluids in the hospital, medicines to correct blood salts, and sometimes dialysis to do the kidneys' job while they recover
